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.

Rapid burial _____.
increases exposure to oxygen
decreases exposure to oxygen
slows down the rate of decay
prevents scavengers from eating organism remains
Answer:Organisms decompose more quickly when they are in contact with oxygen. Most environments exposed to the open air are in contact with plenty of oxygen, so the soft tissues of dead organisms, whether plants or animals, decay quickly. ... For an organism to become a fossil, it must not decompose or be eaten.

b. It should make them want to host more people for social dinners.
c. It should make them want to prepare meals more.
d. It should reduce their sanitary practices (e.g. washing hands) while preparing food.
Explanation:
The options shown above are the only ones that show possible changes in personal behaviors related exclusively to the behavior of a person, who may be suffering from the damage caused by a parasite in the brain. The "e" option does not represent a change in behavior and does not depend exclusively on a sick individual due to the action of a parasite.
As you may already know, the brain governs our body in all factors, for this reason, cysts in this organ can trigger behavioral changes.

Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis, a generally mild but potentially fatal disease, especially in cats and human fetuses. Cats and other felines are considered their ultimate hosts because the sexed phase of their life cycle takes place there, making these animals the primary hosts of the parasite. The asexual phase of the life cycle can occur in any warm-blooded animal, such as other mammals and birds. Therefore, toxoplasmosis is a parasitic zoonosis.
Parasites invade the cells, forming a compartment called the parasitophore vacuole which form cysts in tissues, especially in the muscles and brain. Because the parasite is inside the cells, the host immune system does not detect these cysts. Antibiotic resistance varies, but cysts are difficult to eradicate entirely. Therefore, T. gondii spreads within these vacuoles through a series of binary divisions until the infested cell eventually breaks free.
Some people have flu-like signs and symptoms, which may be:
Swollen lymph nodesHeadacheFeverFatigueWidespread painIn people with impaired immune systems, symptoms may also include:
ConfusionLack of coordinationConvulsionsBlurred vision caused by intense swelling of the retinaIn recent years, several investigations indicate that the parasite can cause changes in the behavior associated with impulsivity, and personality disorders. So, we could predict it zombifies the host by changes in the behavior, because of the damage caused by a parasite in the brain. It is important to consider that the brain governs the body, and cysts found there can trigger these changes.

How do the leaves help trees survive in their respective biomes? A. The temperate leaves are broad and flat to maximize sunlight absorption, while the taiga leaves are long and thin to minimize sunlight absorption. B. The temperate leaves are thin to minimize absorption of sunlight, while the taiga leaves are specialized to store water during the dry season. C. The temperate leaves shed water during the wet season, while the taiga leaves can enter long periods of dormancy during colder weather. D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing.
Answer:
The correct answer is option D.
Explanation:
The temperate leaves grow in temperate forests found in America, Europe, and Asia. This biome comprise of trees have evergreen conifers with needle like leaves. Such leaves can endure wide change of temperature and light. Some vegetation of temperate biome are conifers such as Pine, Hemlock and other. The trees shed their leaves with the beginning of fall and new leaves are delivered in late-winter to protect from the cold.
On other hand, Taiga forest is the biggest biome on the planet. This biome contain conifers with long, slender waxy needles like leaves. These waxy leaves provide security against freezing temperature and from dying drying out. In contrast to temperate they don't sheds their leaves in winter and keep their needles throughout the entire year.
Thus, the correct answer is option D.
Answer:
D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing

Object is not moving Answer 1 Choose... Object is moving towards observer Answer 2 Choose... Object is moving away from observer Answer 3 Choose...
Answer:
Object is moving away from observer.
Explanation:
If a force is applied to an object it starts moving. The object will move towards the observer, this is known as Doppler effect. It is when an observer or the thing under observation moves. There is change in its position due to a force exerted on it. The motion of the object also depends on the direction of force.
CH2OH О, a CH3 H OH OH Н он Identify the macromolecule pictured above. O a Ob Protein Carbohydrate Lipid , ос Od Nucleic Acid
Answer:
Although the pictorial representation is not clear but the question can be answered based on the known structure of each biomolecule. The answer is:
Carbohydrate
Explanation:
Carbohydrate is one of the four biological molecules in living systems. Carbohydrates are composed of long chains of carbon, hydrogen and oxygen in a 1:2:1 ratio i.e (CH2O)n empirical formula.
The structure of carbohydrate is composed of a ketone (C=O) or aldehyde (CHO) functional group and hydroxyll groups (OH). The simplest unit of any carbohydrate is called a monosaccharide. Hence, from the above structure in the question, which consists of long chain of carbon, hydrogen and oxygen atoms, it can be identified as a CARBOHYDRATE.
A surfactant is a chemical that disrupts hydrophilic/hydrophobic interactions, letting normally hydrophobic things dissolve in water (this is how soap cleans grease!). If I have a bunch of enzymes dissolved in water and I add a surfactant, what will happen to the enzyme structure
Explanation:
A good surfactant is going to have a hydrophilic head and a long hydrophobic tail. As a result, a surfactant molecule contains both an insoluble water (or an oil-soluble component) and a water-soluble component. Surfactant molecules will migrate to the surface of the water, where the insoluble hydrophobic group may extend out of the bulk phase of the water, either into the air or, if the water is mixed with oil, into the oil Phase, while the water-soluble head group remains in the water phase. This alignment and aggregation of surfactant molecules at the surface is intended to alter the surface properties of water at the water / air or water / oil interface.

Algae in the genus Caulerpa typically grow to a length of over half a meter and have structures similar to stems,leaves,and roots.Reproduction occurs when adults produce sperm and eggs that fuse to form offspring.Each adult Caulerpa consists of just a single cell,however.Which of the following statements is true?
A) Caulerpa violate the pattern component of the cell theory that all organisms consist of cells.
B) Caulerpa violate the process component of the cell theory that all cells come from preexisting cells.
C) Caulerpa violate both the pattern and process components of the cell theory.
D) The existence of Caulerpa is consistent with the cell theory.
Answer:
D) The existence of Caulerpa is consistent with the cell theory.
Explanation:
This question describes species of algae in the genus, Caulerpa, which is a unicellular organism that possesses structures similar to leaves, stems and roots in plants. It also grows to a length of about 0.5metres. it reproduces sexually by fertilization of gametes (sperm and egg).
According to all these described characteristics of Caulerpa, it's existence is in conformity or accordance with the unified cell theory, which was proposed by three scientists namely: Matthias Scleiden, Theodor Schwann, and Rudolf Virchow in the 1830's. The three components of the cell theory states that:
1. Cell is the fundamental and basic unit of life existence.
2. All living organisms are composed of one (unicellular) or more cells (multicellular).
3. All cells come from already preexisting cells.
Hence, based on the components of the cell theory and the life pattern of Caulerpa i.e. Caulerpa is made up of one cell, it is made from the fusion of preexisting parental cells etc. It is consistent with the cell theory.

As human travel increases, the number of introduced species likely
decreases.
increases
stays the same
is eliminated
Answer: The correct answer to the question is option B
INCREASES.
As human travel increases(As humans move from one place to another),the number of introduced species likely increases because as humans move from one place to another,they introduce new species of organisms to their new environment.
These non-native species grow in this new environment,becomes economically important and doesn't pose any harm to their new ecosystem unlike invasive species that poses a substantial harm.
The number of introduced species are likely to : ( B ) Increases
As Humans migrate from one place to another they introduce new species into their new environment naturally or artificially.
MigrationThe movement of humans or any type of organism comes with the introduction of new species because as they move they take along with them certain species that naturally do not belong to their new environment.
Hence we can conclude that As human travels The number of introduced species are likely to Increase.

The lac operon in Escherichia coli Group of answer choices promotes the expression of lactose-utilizing enzymes when lactose is absent from the environment. prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment. prevents lactose intolerance. prevents lactose-utilizing enzymes from being expressed when lactose is present in the environment.
Answer:
The correct answer is - prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment.
Explanation:
The lac operon or the lactose operon is a operon that is essential for the many bacteria like Escherichia coli for metabolism and transport of the lactose.
In the presence of the lactose in the environment of the cell the lac genes are expressed due to the isomer of of lactose called allolactose binds to the Lac repressor protein and do not allow to bind it to lac operator. But in the absence of the lactose, the lactose utilizing enzymes are not expressed due to repressor bind to the lac operator and prevents the binding of RNA polymerase to the promoter.
