Answer:

C

Explanation:

The proton pump must continuously work against the concentration graident to maintain the electrochemical gradient. If this stops, the ions will flow down their concentration gradients, depolarizing the electrochemical gradient.

How are channel and carrier proteins different?
torisob [31]

Answer:

Carrier proteins undergo a shape change as they move substances across the membrane, while channel proteins do not. Channel proteins move substances across the membrane at a much faster rate than carrier proteins. Carrier proteins can allow much larger substances to cross the membrane than channel proteins do.

The autonomic nervous system is involved in controlling what effectors?
Kisachek [45]

The autonomic nervous system is involved in controlling  a, c, d, e.

what is the Autonomic nervous system?

The peripheral nervous system's autonomic nervous system (ANS) is in charge of regulating critical processes like digestion, breathing, and heartbeat. In the acute stress response, it collaborates with the endocrine system to get the body ready for fight or flight.

Between the central nervous system and the internal organs, the autonomic nervous system acts as a relay. It regulates the exocrine and endocrine glands, smooth muscle, the heart, the lungs, and the heart. These organs are mostly under the autonomic nervous system's control, which is unconscious.

Hence from the above information, we get to understand that ANS helps to control systems, not in our control hence it will regulate all the given options except skeletal muscles as they are under control.

Species in which dark brown fur (D) is dominant relative to light brown fur (d). Using the Punnett square below, predict the fre
Debora [2.8K]

Answer:

<h3>Genotype frequencies</h3>

25% DD

50% Dd

25% dd

or

1 DD: 2 Dd: 1 dd

<h3>Phenotype frequencies</h3>

75% Dark brown, 25% light brown

or 3 dark brown: 1 light brown

Explanation:

Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.

           D                   d

D        DD                 Dd

d        <em>Dd                  dd</em>

<em />

25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown,  since it has two copies of the dark brown fur allele (DD)

50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown  fur (d).

25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
