Which mechanism is responsible for the changes in fish size between generation 1 and generation 100?
MrRissso [65]

The mechanism  responsible for the changes in fish size between generation 1 and generation 100 is the gene flow mechanism.

<h3>What is the gene flow mechanism?</h3>

Individuals may migrate from one group or region to another as part of another evolutionary mechanism. Interbreeding between the migrant individuals and the new population adds their genes to the local population's gene pool. The population's gene flow is established as a result.

For instance, when wind takes seeds far outside the range of the parent plant population, gene flow occurs. Another illustration might be when animals leave a herd. They are compelled to migrate as a result, adding new genes to the gene pool. Because gene flow makes gene pools more similar to one another, it tends to increase the similarity between remaining populations of the same species.

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.
