Kay [80]

Answer:

1. Part A: No

2. Part B: Yes

3: Part C : Yes

4: Part D : No

Explanation:

1) Part A: Facilitated diffusion of glucose into a muscle cell:

No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose

2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:

Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.

3) Part C: Uptake of potassium ions by red blood cells:

Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.

4) Part D: Active uptake of lactose by the bacteria in your intestine

No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.

What caused Earth to develop layers as it cooled?
Dominik [7]
The answer is difference in density. We know that the high central density suggests the earth must be rich in nickel and iron and that much of the core must be liquid. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.

Tomtit [17]
In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents. 
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t

The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt

The black horse that is a pacer that can produce this offspring will be:
Bbtt

Therefore, the brown horse's genotype must be:
bbTt

The offspring will receive b from both parents and t from both parents.
