A, incomplete dominance

Answer:

The correct answer is option A "incomplete dominance".

Explanation:

In this example, after making a cross-breeding between two different snakes, all the baby pythons were brown with a faint diamond pattern. This phenotype is different of the phenotype of the two parents (a solid brown male python, and a tan black diamond female), and corresponds to an intermediate phenotype between them. This a characteristic inheritance pattern as of incomplete dominance, at which no allele is completely expressed over the other resulting in the offspring having a third intermediate phenotype.

Which of the following is NOT a function of Sertoli cells?
zalisa [80]

Answer:

The correct answer is option - d. Production of primary spermatocytes.

Explanation:

The accessory cells or supporting cells present within the seminiferous tubules of reproductive system termed as the Sertoli cells. They play various roles in the body and reproductive system.

Sertoli cells make blood-testis barrier in adjacent Sertoli cells in the seminiferous tubules. These cells secrete different types of enzymes and hormones such as inhibin which are also secreted by ovary and placenta in females. Sertoli cells produce seminiferous tubular fluid to provide nutrition to the sperm. Apoptotic germ cells are timely eliminated by these cells.

Thus, the correct answer is option D. Production of primary spermatocytes.

I have mutant cells that make no pfk2enzyme. i measure rates of oxygen consumption in these mutant cells and compare them to wil
Kazeer [188]

The correct answer is that mutant cells will exhibit diminished oxygen consumption; decreased glycolysis results in decreased Kreb's cycle and electron transport chain.

The PFK2 enzyme catalyzes the generation of F26BP, this binds with the allosteric site of PFK-1 and increases the affinity of PFK-1 with F6P and also decreases the affinity of allosteric inhibitors citrate and ATP to PFK-1. Thus, PFK-1 will combine with F6P at a greater rate.

This ultimately results in more glycolysis, thus, more ETC and more consumption of O2. If there is no PFK2, then there will be a reduction in glycolysis, TCA, ETC, and consumption of oxygen.

The PFK2 is an enzyme accountable for monitoring the rates of gluconeogenesis and glycolysis in the human body. In the absence of glycolysis, there will be a reduction in TCA, ETC, and consumption of O2.

Didn't even mean to do this
Fynjy0 [20]

Answer:

If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.

Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.
