What is the relationship between the fundamental niche and the realized niche of a species? A) The fundamental niche is the only conditions a species can tolerate and the only resources that it can potentially use, while the realized niche is the part that a species actually uses.
B) The realized niche is the range of conditions a species can potentially tolerate and the range of resources that it can potentially use, while the fundamental niche is the part that a species actually uses.
C) The realized niche is where a species can live and function, while the fundamental niche is where a species actually lives.
D) The fundamental niche is the range of conditions a species can potentially tolerate and the range of resources that it can potentially use, while the realized niche is the part that a species actually uses.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

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.

explanation:

the correct answer is d

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
