Answer:
Diffusion
Explanation:
Substances like CO2 and water move into and out of a cell by diffusion from an area of high concentration to an area of low concentration.
Answer:
The correct answer will be- distal
Explanation:
In anatomy, the anatomist defined the standard position and movement of the bones of the skeletal system by universal anatomical terminologies.
The directional position of the bones of arms and legs is represented by the proximal and distal plane.
The proximal direction represents the bone closest to the point of origin or reference while distal represents the bone closest to the farthest away from the reference. Since the left wrist is farther from the reference or the elbow therefore, it is considered distal to the elbow.
Thus, distal is the correct answer.
Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
