<span>It's because the genome has undergone mutation which means the foetus has a post anal tail and when the fetus matures the genome triggers absorption in development to remove unnecessary components by disintegrating the unnecessary cells (webbing, tail, etc). When this is not removed it is because the genome did not send the signal for absorption.</span>

How are ocean ridges and trenches related? Describe their relationship in
True [87]

Terms that are asked to be used in the response are bolded;

     Ocean ridges and trenches are related in a few ways. One of the ways is being created from the movement of tectonic plates on the mantle when they diverge and converge. When tectonic plates diverge they "pull apart" and create trenches. When they converge they "push together" and create ridges, subduction happens here. The tectonic plates move on the mantle of magna from convection currents creating these different boundaries.

Have a nice day!

Rudiy27

Answer:

Because a drug acts on one type of receptor does not mean that it will act on another type.

Explanation:

As humans, we have receptors for two kinds of beta adrenergic compounds such as catecholamines. Cardiac muscle cells have beta 1 receptors that promote increased heart rate. Some drugs that slow heart rate are called beta blockers. Smooth muscle cells, however, have beta 2 receptors which mediate muscle relaxation. Blockers of these effects are sometimes used to treat asthma. The use of beta 2 antagonist drugs may be useful in asthma because a drug acts on one type of receptor does not mean that it will act on another type.
