Answer:
3/16
Explanation:
Given,
Black coat color is dominant over brown coat color.
Long mane is dominant over short mane.
BBLL X bbll =
F1: BbLl = Entire progeny has black color and long mane
BbLl progeny will produce BL, Bl, bL and bl gametes. When they interbreed, the resultant F2 progeny will be in 9:3:3:1 dihybrid ratio. Hence in F2,
BBLL : BbLL : bbLl : bbll = 9 : 3 : 3 : 1
3/16 progeny will have bbLl genotype hence 3/16 progeny will have brown, long mane.
Answer: D. Epinephrine
Explanation:
During perceived danger the fight-or-flight response includes faster heart beat, quickened breath, tense muscles and thought speed up. This co-ordinated set if physiological changes is triggered by two hormones of the adrenal gland, epinephrine and norepinephrine.

Answer is epinephrine
Answer:
Humans release carbon dioxide (CO2) into the atmosphere through cellular respiration. This CO2 is used by plants during photosynthesis. During photosynthesis, plants release oxygen (O2) into the atmosphere. The oxygen is used by animals in order to carry out cellular respiration.
