Answer:

Explanation:

Albedo is the radiation reflected by the earth´s surface to the universe.

Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.

Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.

The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

Complete Question:

1. Organisms don’t all reproduce the same way. However, by comparing the ____ of these organisms, many similarities between them are ____

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.

Group of answer choices.

A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology

Answer:

1.5mm

Explanation:

According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.

This means that the diameter of the field of view of Mary's microscope can be calculated as follows:

Diameter of each pollen × no. of pollen that fit in

= 0.3mm × 5

= 1.5mm

Hence, the diameter of the field of view of Mary's microscope is 1.5mm.

Cystic fibrosis is an autosomal recessive condition caused by a mutation in the CFTR gene that alters Cl- and Na+ transport, leading to excesive mucus accumulation in aerial and digestive tracts.

Cystic fibrosis is an autosomal recessive condition in which the mutation of a diallelic CFTR gene that codes for the channel CFTR  protein (cystic fibrosis transmembrane conductance regulator) is responsible for the affection.

The CFTR protein expresses in the luminal portion of the secretory and absorptive epithelial membranes, and it is involved in Cl- and Na+ transport.

Given that defects in the CFTR protein take to a defective regulation in the Na+ channel, cystic fibrosis characterizes by alterations in electrolytes secretions and absorption. There are two significant physiopathological mechanisms:

1) altered Cl- secretion in submucous glands,

2) increased Na+ absorption and consequent electrolytes hyperabsorption in the superficial epithelium.

Patients with cystic fibrosis are incapable of increasing their secretory transport. On the contrary, the increased epithelial Na+ conductance and the altered permeability to Cl- and water lead to hyperabsorption in the patient epitheliums.

The superficial liquid layer in the aerial vias decreases, mucus is not released from mucous glands, and the mucociliary clearance is strongly altered in aerial vias. Mucus accumulates in the lungs, digestive tract, and other areas.

Most people have two copies of the normal allele (h0m0zyg0us dominant genotype)and produce the functional CFTR protein form.

Patients with cystic fibrosis have two copies of the mutated allele (h0m0zyg0us recessive genotype), producing the protein's mutated and dysfunctional form.

Heter0zyg0us people possess only one normal CFTR allele and a mutated form of the same gene. These alleles are codominant, meaning that noth of them are expressed. They can produce a normal protein and a mutated protein.

Given that the normal allele produces enough functional CFTR protein, these individuals do not have any adverse effects, and the mutated allele is recessive at a physiological level.

To sum up, Cystic fibrosis is an autosomal recessive condition -not sex-linked- that causes the unfunctional form of the CFTR protein,  and alters Cl- and Na+ transport. Consequently, there is an accumulation of mucus in the respiratory and digestive tract, among other organs, that might be lethal.

Answer:ribosome uses the sequence of codons in mRNA to assemble amino acids into a polypeptide chain

Explanation:

Answer:

C

Explanation:

Natural Selection can cause micro evolution, or a change in allele frequency over time

An allele becomes more common in a population. So, the correct option is (C).

Allele frequency is also known as gene frequency. It is defined as the relative frequency of an allele at a particular locus in a population, expressed as a fraction or percentage. It is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.

It forms the basis of many population and medical genetic studies. Many evolutionary forces change allele frequencies where allele frequencies can be used to trace past evolutionary events.

Allele Frequency is expressed as:

[tex]1 = p^2 + 2pq + q^2[/tex]

p and q each represent the allele frequency of different alleles.

Thus, an allele becomes more common in a population. So, the correct option is (C).

Answer:

basophils

Explanation:

Basophils are a class of white blood cells known as granulocyte, which also include neutrophils, eosinophils, and mast cells. These cells (basophils) are generated in the bone marrow as other white blood cells. When stimulated, basophils degranulate to release histamine, proteoglycans, and proteolytic enzymes and thus mediate immune responses. This process of degranulation occurs when a specific antigen binds to the IgE receptor on the basophil. Moreover, basophils may also be activated by inflammatory mediators (e.g., complement factors such as C5a and C3a, chemokines, etc).

Explanation:

I just took the test

When a sperm fertilizes an egg, the fertilized egg, also known as a zygote, will travel from the fallopian tube to the uterus, where it will implant and grow into a fetus. Therefore, the correct option is B.

A fertilized egg is also known as a zygote. It is a single cell that results from the union of a sperm and an egg during fertilization. Fertilization typically occurs in the fallopian tube of a female reproductive system when a sperm successfully penetrates and merges with the egg.

The egg is released from the ovary and travels through the fallopian tubes towards the uterus. It is in the fallopian tubes where the egg can be fertilized by a sperm, forming a zygote.

The zygote will then continue to travel through the fallopian tube towards the uterus. As it approaches the uterus, the zygote will undergo several cell divisions, forming a ball of cells known as a blastocyst.

The blastocyst will then implant into the lining of the uterus, where it will continue to grow and develop into a fetus. The cervix, which is the lower part of the uterus, plays a role in pregnancy by keeping the fetus inside the uterus during gestation and then opening to allow for delivery during childbirth.

Therefore, option B) the fallopian tubes and uterus is correct.

Answer:

is expressed roughly equally in both sporulating and nonsporulating yeast

Explanation:

A DNA microarray (also called DNA chip) is a microchip-based testing platform which can be used to analyze and compare gene expression profiles between samples. A DNA microarray contains microscopic DNA spots attached to a solid surface, where each spot corresponds to thousands of copies of a specific DNA sequence (i.e., probes). Subsequently, cDNA 'target' molecules obtained by reverse transcription from RNA are then hybridized to a microarray. This process of hybridization can be quantified by using fluorophore-labeled targets that determine the level of the expressed gene (transcript) in the target sample. In a DNA microarray, the intensity and types of color in each spot indicate the presence and level of each specific transcribed gene in the samples. In consequence, the presence of yellow spots in the DNA microarray indicates approximately equal expression levels of the corresponding gene in both yeast samples.

Answer:

The correct answer is: in neurons, the most used ion channels in the production of action potentials are the channels that allow fo passage of sodium and potassium.

Explanation:

Neurons must be able to transmit and receive signals in order for the nervous system to operate. Because each neuron has a charged cellular membrane (a voltage differential between the interior and the exterior), the charge of this membrane can vary in response to neurotransmitter molecules generated by other neurons as well as external stimuli. The membrane potential is the difference in total charge between the interior and outside of the cell. This membrane potential exists thanks to the state of ion channels that may or may not allow the passage of certain ions.

A substance called a neurotransmitter allows a neuron to accept input from other neurons. The neuron will transmit the signal to downstream neurons if the input is powerful enough. The opening and shutting of voltage-gated ion channels, which produce a transient reversal of the resting membrane potential to form an action potential, are used to transmit a signal within a neuron (in one direction only, from dendrite to axon terminal). The polarity of an action potential changes across the membrane as it travels down the axon. The signal then activates other neurons once it reaches the axon terminal.

The target neuron is depolarized to its threshold potential (-55 mV) by a stimulation from a sensory cell or another neuron, and Na+ channels in the axon hillock open, initiating an action potential. The neuron totally depolarizes to a membrane potential of around +40 mV after the sodium channels open. As Na+ channels open, the action potential moves along the neuron.

The cell's membrane voltage is "reset" to the resting potential after depolarization is complete. The Na+ channels shut, signaling the start of the refractory phase in the neuron. Voltage-gated K+ channels open at the same moment, allowing K+ to escape the cell. The membrane potential returns to a negative state as K+ ions exit the cell. The cell becomes hyperpolarized when K+ diffuses out of it, resulting in a membrane potential that is lower than the cell's usual resting potential. The sodium channels revert to their resting state at this moment, ready to open again if the membrane potential rises over the threshold potential again.
