We can confirm that the adrenal medulla's hormonal secretion consists of primarily epinephrine. 
<h3>What is Epinephrine?</h3>
As stated in the question, eighty percent of the adrenal medulla's hormonal secretion is epinephrine, which affects receptors in the cardiovascular and respiratory systems, gastrointestinal tract, liver, and other endocrine glands. Its main functions are to affect heart rate and blood sugar levels. It is also known as adrenaline. 
Therefore, we can confirm that the adrenal medulla's hormonal secretion consists of primarily epinephrine, better known as adrenaline.

Answer:
5) The parents phenotypeis tall because they are both Tt. The T is the dominant trait.
6)25% will be TT
-because only 1 of the four squares is TT
7) 50% will be Tt
- because 2 of the four squares is Tt
8) 25% will be tt
- beacuse 1 one 4 squares is tt
9) 75% of offspring will be Tall
- because T is domanint and 3 of the 4 sqaures has T
10) 25% of off pring will be short
-Because t is recesive and only 1 of the 4 sqaures has both tt. You need two recesive genes to have that trait
