Which of the following best characterizes an adaptive radiation? Which of the following best characterizes an adaptive radiation? Natural selection is particularly intense because disruptive selection occurs. A single lineage diversifies rapidly, and descendant species occupy many habitats and ecological roles. Descendant species occupy a large geographic area. Species recover after a mass extinction.

A single lineage diversifies rapidly, and descendant species occupy many habitats and ecological roles.

Explanation:

In biology, adaptive radiation refers to a phenomenon in which organisms tend to diversify rapidly from a common ancestor and then radiate into a multitude of new organisms.

These new organisms may have to change their environment in order to survive. This change in their environment creates new challenges and may lead to the appearance of new environmental niches.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
