The diagram shows molecules moving across a selectively permeable membrane. The smaller circles represent salt molecules, and th
e dashed line represents the membrane. Which statement best describes the movement of the salt molecules? Their movement requires energy.
Their movement represents active transport.
They move from high concentration to low concentration.
They become unevenly distributed.
They move from high concerntartion to low concertration
Explanation:
the diagram is not provided but am guessing there were bigger circles which could not pass through, which shows that the membrane was selectively permeable to smaller salt molecules. The movement across the membrane did not require energy.
The correct answer of the given question above would be option D. CHROMOSOMAL POTENTIAL. A change in the frequency of alleles in a gene pool can be explained by all of the following except the chromosomal potential. <span>A change in allele frequency is more likely to produce microevolution. Hope this answer helps.</span>
C. Exponential growth occurs when there is unlimited resources. Since there is a surplus of food, there are a lot more babies are born because of the favorable circumstances.
