What is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems

Expected outcome: HH, Hh, Hh, and hh

The phenotypic ratio of the offsprings will be 3 hairy stems : 1 hairless stem

Explanation:

This question involves a single gene coding for possession of hair on stems or not in tomato plants. The allele for hairy stem (H) is dominant over the allele for a hairless stem (h).

According to this question, if two tomato plants that are heterozygous for hairy stems (Hh) are crossed, the following gametes will be produced by each parent: H and h. Using these gametes in a punnet square, the following proportion of offsprings will be produced:

HH, Hh, Hh, and hh

3 hairy stems (HH, Hh, Hh) : 1 hairless stem (hh).

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
