If one builds a canal linking a predator-rich pond to a predator-poor pond, then what type of selection should subsequently be most expected among the mosquitofish in the original predator-rich pond, and what type should be most expected among the mosquitofish in the formerly predator-poor pond?

The answer is directional selection.

Explanation:

Selection types can be given as stabilizing, disruptive and directional selection and the example given in the question is an example of directional selection.

In directional selection, the phenotypes of the species take role in determining their chances of survival and in this situation the one will have the advantage over the other species in terms of survival because they were initially living in different conditions therefore they will experience directional selection but in opposite directions meaning one will have a positive impact and the other negative.

I hope this answer helps.

the answer to your question is slate

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
