C is the answer
:) for your question (im writing extra cause answer is too small)
Answer:
B) A difference in pressure across a distance.
In order to answer this, you will need to set up a Punett Square (I have attached a picture).
Since Rr is the genotype of round seeds, we know that round must be dominant to wrinkled, and therefore represented by the allele, R.
Since rr is the genotype of wrinkled seeds, we know that wrinkled must be the recessive trait, and there represented by the allele, r.
Since the Punnett Square shows that the genotype ratio is 2Rr : 2rr, or simplified, 1Rr : 1rr, we now know that there is a
50% chance the offspring will have wrinkled seeds.
Answer:
Correct option is B.
Explanation:
Sympathetic nervous system is known as primary process to regulate the body fight or fight response, which is also called as sympatho adrenal response. This response end in the adrenal medulla which produce acetylcholine, and active the large secretion of adrenaline also known as epinephrine, and to a less extent noradrenaline or norepinephrine from it.
Sympathetic stimulation is constantly active, and maintain a basic homeostasis level in living organisms.
