In garden peas, the axial (A) flower position is completely dominant to the terminal (a) flower position. You cross a true-breed

ing axial flowering plant to a true-breeding terminal flowering plant. What is the genotype of the true-breeding axial flowering plant?

Answer:

AA

Explanation:

A true breeding organism for a particular trait is an organism that would produce progeny  with the same trait whe self fertilized.

Hence, since axial flower is represented by the allele A, a true breeding flowering plant will have the genotype AA.

Axial flower (A) is dominant over terminal flower (a).

True-breeding axial flowering plant will have the genotype AA.

True breeding terminal flowering plant will have the genotype aa.

AA is crossed with aa.

AA   x   aa

offspring: Aa, Aa, Aa and Aa.

All the offspring will exhibit axial flowering.

How has waste leaving a cell affected its surface area to volume ratio?
lapo4ka [179]

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.  

One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
