Which of the following best describes the process of adaptive radiation?
a. genetic material moves within parts of a population or from one population to another
b. two species evolve to a point at which they can interbreed.
c. a single kind of animal or plant diversifies to fill many available niches.
d. mutation intensifies in a population as a result of environmental factors.

c. A single kind of animal or plant diversifies to fill many available niches.

Explanation:

The adaptive radiation can be define as a process in which number of species develop from a single ancestral species. This leads to the process of speciation. This happens when the new resources are available in the environment, scarcity of resources, changes in the environmental conditions, development of new niches.

The animal and plant species diversifies according to their niches. The niche can be define as the functional role that an organism performs. With the increase in niches the diversity of the living beings also increase hence, this will lead to the adaptive radiation.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
