Answer:

The target organs of this gland are the kidneys, bones and intestines.

Two hormones secreted by the adrenal medulla are adrenaline and norepinephrine

Explanation:

The parathyroid gland controls calcium in the extracellular fluid through its influence on the target organs named above.

Adrenaline stimulates lipolysis, glycogen degradation and also increases blood flow to the heart and muscles.

Norepinephrine stimulates lipolysis and contracts arterioles and venules

In studying the gene pool of a population, you find that 21% of the population exhibits the recessive trait for eye color and th
Naily [24]
In order to solve this problem we use these formula:
<span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population
q = % recessive allele in the population
p2 = % homozygous dominant individuals
q2 = % homozygous recessive individuals
2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>

after a power stroke, the myosin head must detach from acting before another powerstroke can occur. what causes
kompoz [17]

The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.

The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.

Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.
