The idea that speciation occurs in bursts, between long periods of genetic equilibrium is called — a. punctuated equilibrium. c. genetic drift. b. stabilizing selection. d. gradualism. select the best answer from the choices provided a b c d

a. punctuated equilibrium.

Explanation:

The idea that speciation occurs in bursts, between long periods of genetic equilibrium is called punctuated equilibrium.

ANSWER:

The correct option is A: Punctuated Equilibrium. Punctuated equilibrium is a theory that suggests that changes in species take place in rapid bursts.  

EXPLANATION:

the correct answer is c   with the systems

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
