About thirteen different species of finches inhabit the Galápagos Islands today, all descendants of a common ancestor from the South American mainland that arrived a few million years ago. Genetically, there are four distinct lineages, but the thirteen species are currently classified among three genera. The first lineage to diverge from the ancestral lineage was the warbler finch (genus Certhidea). Next to diverge was the vegetarian finch (genus Camarhynchus), followed by five tree finch species (also in genus Camarhynchus) and six ground finch species (genus Geospiza). If the six ground finch species have evolved most recently, then which of these is the most logical prediction?

Answers

Answer 1

Answer: Firstly it should be noted that, the chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. On this wise, their genomes would be more similar to each other than are the genomes of the five tree finch species. Secondly, they should be limited to the six islands that most recently emerged from the sea.

Thirdly, they should share fewer anatomical homologies with each other than they have shared with the tree finches.

Fourtly, their genomes should be more similar to each other than are the genomes of the five tree finch species.

Which of the following is not an example of energy transformations in an ecosystem?
a. sunlight driving photosynthesis in plants
b. herbivores feeding on plants
C. predators feeding on herbivores
d. none of the above

Answers

Answer:

d. none of the above

Explanation:

Energy, which refers to the ability to do work, can exist in different forms. The process of changing energy from one form to another is called TRANSFORMATION OF ENERGY. In an ecosystem, all organisms require energy in order to perform their life processes. They acquire these energy in different forms and convert it to a usable form by their cells (chemical energy) in ATP.

For example, solar energy in Sunlight is used by plants to drive their photosynthetic process and change it to chemical energy in glucose. Also, predators and herbivores feeding on herbivores and plants respectively converts one form of energy to another. Hence, all options are examples of energy transformation. None of the above is the correct answer.

Answer:

I think the correct answer is d ,

because all of them are an example of energy transforming in an ecosystem.

Answer:

Animal populations can change from one season to another, so it’s important to restrict hunting to seasons when the population is high. Such a restriction helps prevent a severe drop in population, which could threaten the species. It’s also important to limit hunting during breeding seasons to increase the possibility of offspring reaching adulthood.

A. understand the viewpoint of other people.

B. realize that the term heavy describes an object one way and the term big describes it another way

C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

The answer is C

Explanation:

Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.

However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.

He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.

Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

TLRs are Group of answer choices the coatings of pathogens by complement. present in intact skin, sebum, tears, etc. phagocyte receptors that detect PAMPs. nonspecific leukocytes that secrete toxins onto the surface of virally infected cells. molecules that damage cells, resulting in cell lysis.

Answers

Answer: Phagocyte receptors that detect PAMPs

Explanation:

TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)

In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses.

At temperatures higher than the maximum growth temperature for an organism:

a. proteins are permanently denatured. membranes become too fluid for proper function.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.

Answers

Answer:

The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.

Explanation:

The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.  

When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.

Answers

Answer:

Temporal isolation

Explanation:

Temporal isolation, a type of reproductive barrier caused by variations in the timing of mating receptivity, activity, or fertility, prohibits interbreeding between different but closely related species.

What is the temporal barrier in reproductive isolation?

In biology, temporal isolation is a form of reproductive isolation mechanism that prevents members of closely related species from mating and creating hybrid offspring.

Temporal isolation refers to the situation where two or more species reproduce at various periods. For instance, three different types of orchids live in the same rain forest.

This mechanism arises from differences in the timing of crucial reproductive events.

Therefore, Temporal isolation reproductive barrier will most likely be working against that possibility.

In a cladogram (a type of phylogenetic tree), clades are groups of related organisms. In the past, phylogenetic lists built clades using the idea of parsimony, that the pattern that uses the fewest evolutionary changes is the most likely to be correct. Today, with the use of computers and DNA sequences, the explanation that is thought to be the best is ___________ .

Answers

Answer:

one with the fewest number of genetic differences in the nucleotide sequence.

Explanation:

A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the laboratory.

Answers

Answer:

The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

Explanation:

Mutation is a process that occurs from time to time to the genetic material of living cells. Mutation is a change in the nucleotide sequence of a DNA or gene. It is usually caused by errors during replication or induced by an external substance called MUTAGEN.

A mutagen is any substance that causes mutation in an organism. Hence, according to the question, the chemical substance which is thought to be a mutagen will change the cells after being exposed to the chemical, and this change is passed to the next generation of cells.

N.B: Since mutation affects the gene, it is passed on to the offsprings during reproduction.

Independent variable: _______ Dependent variable: _______ If the amount of milk a person drinks increases, the strength of his or her bones will stay the same. Independent variable: _______ Dependent variable: _______

Answers

Complete Question:

Part A: Identifying Variables

Read the following hypotheses and identify the variables.

If the number of cigarettes smoked increases, then the risk for lung cancer increases.

Independent variable: _______

Dependent variable: _______

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.

Independent variable: _______

Dependent variable: _______

If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.

Independent variable: _______

Dependent variable: _______

Answer/Explanation:

Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.

Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.

In the above given hypotheses, the dependent and independent variables are shown below:

1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".

"Risk for lung cancer" => dependent variable

Number of cigarettes => independent variable

2. "number of shark attacks on humans" is dependent on "number of sharks swimming".

Dependent variable => number of shark attacks on humans

Independent variable => number of sharks swimming

3. Dependent variable => strength of bone

Independent variable => amount of milk a person drinks

Answer:

Lab: Heart Rate  

Part A: Identifying Variables

The dependent variable happens as a result of values/changes associated with the independent variable.

Independent variable: number of cigarettes smoked

Dependent variable: risk for lung cancer

Independent variable: number of sharks swimming in a coastal region

Dependent variable: number of shark attacks on humans

Independent variable: amount of milk a person drinks

Dependent variable: the strength of his or her bones

Part B: Heart Rate

Hypothesis: If I hold my breath for 30 seconds, then my heart rate will

(choose 1) increase/decrease.

Independent variable: holding my breath

Dependent variable: heart rate

Part C:

The heart rate decreases because oxygen exchange in the lungs decreases.

This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.

Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.

Example: Increase in activity—jumping jacks

Hypothesis: If I do five jumping jacks, then my heart rate will increase.

Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.

Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.

Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

Which of the following describes a positron emission tomography (PET) scanner? 1: A device that uses magnetic fields to produce images of brain structures 2: A device that uses magnetic fields to measure blood flow 3: A device that uses radioactive fluid to determine the active areas of the brain 4: An X-ray device that can create a 3D model of the brain

Answers

Answer:

3: A device that uses radioactive fluid to determine the active areas of the brain

Explanation:

A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

Depending on the type of exam, the radiotracer is injected, swallowed or inhaled as a gas. It eventually accumulates in the area of the body under examination. A special camera or imaging device detects radioactive emissions from the radiotracer. The camera or device produces pictures and provides molecular information.

An organism is _______ for a gene if it has two copies of the same allele for the gene.

Respond to the following based on your reading.

In the previous section, you learned that the allele for brown eyes (B) is dominant, and blue (b) and green eyes (g) are recessive, while green eyes are dominant over blue eyes. What eye color would someone with the following genotypes exhibit? (a) BB, (b) Bb, (c) gb, (d) Bg, (e) bb.
Discuss the law of segregation and explain why each organism has two copies of the gene for each trait expressed.
What type of experiments did Mendel conduct, and what did he want to find out about the heritability of the seven traits he chose to study?

Answers

Answer:

1. Purebred (N.B: the exact word is considered a foul word)

2. Phenotype

3. Linked

4. Segregation

5) (a) BB- Brown eyes

(b) Bb- brown eyes

(c) gb- green eyes

(d) Bg- brown eyes

(e) bb- blue eyes

The other questions are explained below

Explanation:

1. A purebred organism is that which possess two copies of the same alleles in its genotype. An allele is a contrasting form of a gene. If the two alleles are the same, the organism is said to be purebred.

2. Phenotype of an organism is the observable characteristics of the organism. It is determined by the organism's genotype in interaction with its environment.

3. Mendel's law of independent assortment states that the alleles of a gene will separate into gametes independently of another gene unless the genes are linked. Linked genes are genes that are too close to each other on a chromosome and hence, do not sort independently. They're rather inherited together.

4. Mendel’s law of Segregation governs which allele is expressed in an individual. According to this law, an organism will express the allele it randomly receives from each parent. If an organism receives two different alleles, it will express the allele that is dominant. In other words, an organism will only express the recessive trait if it receives two recessive alleles from both parents.

5. a) BB- Brown eyes because the organism is purebred for the dominant (brown) allele

(b) Bb- brown eyes because the brown allele (B) will mask the expression of blue allele (b) and express itself.

(c) gb- green eyes because the allele for green eyes (g) is dominant over the allele for blue eyes.

(d) Bg- brown eyes because the brown allele (B) is dominant over the allele for green eyes (g), hence, it will mask its expression

(e) bb- blue eyes because the organism is purebred for the blue allele i.e. same recessive (blue) alleles in the gene.

6. The law of segregation as proposed by Mendel states that the alleles of a gene will separate into gametes during gamete formation (meiosis). This is done in such a way that each gamete contains only one allele of each gene. Hence, an organisms will contain two copies of a gene because they receive each copy (allele) from each parent during fusion of their gametes.

7. Mendel conducted an hybridization experiment i.e. a cross involving two individuals that possess different traits. He did this in order to find out how different traits/characteristics in organisms were transferred from one generation to another. Mendel chose the pea plant for his experiment because they could easily be manipulated for self and cross pollination. Mendel studied seven (7) different traits or characteristics in pea plants including height, seed shape, seed color, flower color etc.
