Answer:

a) aaBb

b) Dimples and short eyelashes

c) 50%

d) 25%

Explanation:

Let the gene for dimples be A

Let the gene for eyelashes be B

a) Woman has no dimples (aa) and is heterozygous for long eyelashes (Bb) so her genotype : aaBb

b) Man is heterozygous for dimples (Aa) so he will have dimples and it is already given that he has short eyelashes (bb)

When aaBb X Aabb :

        aB         ab

Ab  AaBb    Aabb

ab   aaBb    aabb

c) Out of the four possible combinations, aaBb and aabb will be born without dimples so this couple has 50% chance to produce a child without dimples.

d) Only aabb will be born without dimples and without long eyelashes so the couple has 25% chance to produce a child without dimples and without long eyelashes.

ASHA 777 [7]

Answer:

Stored as fat

Explanation:

The body requires a variety of macro nutrients for building blocks to fortify the body and keep it functioning. One of the important building blocks are amino acids that are derived from proteins. These are broken down in the stomach by protein digestion enzymes by amylase, proteases and hydrochloric acid.

In the even that the body has taken in too many units of protein this will be stored in the liver as glycogen. This is a form of "animal carbohydrate" or "animal sugar."

The glycogen stores will remain there for a reservoir for energy whenever the body requires it. In the event of overeating the body will store the glycogen in a more concentrated form, fat via the fatty acid synthesis pathway.
