Answer:
The answer is Norepinephrine.
Explanation:
Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.
Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.
I hope this answer helps.

Answer:
what are the choices for the adaptation
If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.
Allele for short hair (S) is dominant on the allele for the long hair (s).
The texture of hair texture is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).
Now coming towards the question:
- A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.
Phenotype of the female will be Rough and long hair.
- A male guinea pig is homozygous dominant for hair texture and hair length.
Phenotype of the male will be Rough and short hair.
Hope it help!
