Answer:
D.) If the homozygous tall plant (TT) crosses with a homozygous short plant (tt), then all the F1 plants become heterozygous tall plants (Tt).
Explanation:
Homozygous indicates that the alleles in the genotype are the same. Therefore, the genotype for homozygous tall plants is (TT) and the genotype for homozygous short plants is (tt).
After performing a cross, we know that all of the children will have the heterozygous genotype (Tt).
There is only two possible offspring.
Bb and bb
Homo is the same
Hetero is different
b b
B <u> Bb </u> <u> Bb</u>
b <u> bb </u> <u> bb </u>
The answer is diffusion.
The most important mechanism that enables oxygen and carbon dioxide (but as well other small molecules such as glucose, amino acids, wastes) across capillary walls is diffusion. Diffusion is a net movement of molecules through some barrier from an area of high concentration to the area of low concentration. When blood rich in oxygen reaches capillaries close to the cell, now there <span>is </span>more oxygen in the capillaries than in the cells and by diffusion, oxygen will pass capillary walls and enter the cell. Since blood in capillaries lacks in carbon dioxide, it will easily leave the cells and enter the blood. It should be taken into consideration that capillary walls may be fenestrated, continuous, and discontinuous which can affect movement through them.

List two possible advantages of asexual reproduction to the organisms who reproduce sexually.
<h3> Well heelo there! i shall help chu! ^v^</h3>
Asexual: Requires 1 organism.
Sexual: Requires 2 organisms.
<h3>The advantages of asexual reproduction are:</h3>
- It's faster
- There is more production
- Organisms that are born are exactly the same

two new strands of DNA. The result is two DNA molecules consisting of one new and one old chain of nucleotides.
