Answer:
The correct answer is C) gene flow
Explanation:
The biological species concept defines what is a species. It says that a species is a group of individuals in a population that interbreed with each other. So there should be gene flow between the members of the population to come under species.
Appearance does not define that two individual are of same species because even different species can look same for example Western meadowlarks and eastern meadowlarks looks identical to each other but they do not interbreed so there is no gene flow between them so they are not same species.
Therefore the primary criteria for determining species boundaries is gene flow.
Answer:
False
Explanation:
In DNA, there are four possible nitrogen bases – adenine (A), guanine (G), cytosine (C), and thymine (T). In DNA, nucleotides combine to form two long chains that intertwine with each other, like a ladder that has twisted into a spiral.
Answer:
the cell membrane is the semi-permeable protective cover that keeps the cell held together. the cytoplasm is semi-fluid within the cell membrane that keeps the cell in shape.
Explanation:
AN-PEP enzyme refers to a dietary supplement, which has been shown to dissociate gluten in the stomach. It has been proven to help the individuals suffering from Gluten sensitivity or Celiac disease. The scientific name of the enzyme is Aspergillus Niger prolyl endoprotease.
However, certain structural differences would take place between AN-PEP, which prevent the enzyme from digesting the peptides. Some of the differences like amino acid differences would be expected in the active site, and in the regions, which influence the folded composition of the active site.
