This food web represents a community in a rain forest.
nasty-shy [4]

Answer:

coatis would increase

sloths would increase

fruit bats would increase

Explanation:

The boa constrictor in this food chain is the top predator, thus it is on the top of the food chain. It preys on several of the animals on this list, such as the coati, sloth, and fruit bats, so it is regulating their numbers. If the boa constrictor is removed from the ecosystem, the ecosystem will lose its predator, so the animals on which the boa constrictor preyed upon will have no threat, thus will experience rapid increase in their numbers. The coatis, sloths, and fruit bats, all will be predator free in this scenario, so they will all experience increase in their population, which in turn will have big effect on all other species in the ecosystem.

In the mechanism, the messenger RNA modifies its shape in response to a small molecule, and therefore, changes its binding capability for the regulatory region of an operon and a gene. His studies suggested that genes and proteins are co-linear. If the section of the intron in the gene gets mutated, then the protein generated by the protein also gets mutated.
