The right answer is A) Salt in the bloodstream causes fluids to enter the blood from surrounding cells, due to osmosis.
The circulatory system of the body is a highly flexible vascular system, which has the ability to open and distend new capillaries and veins in order to cope with an increase in fluid volume.
The term "Higher blood pressure" implies that an excess of salt leads to the retention of additional fluid within the arterial circulatory system, which would cause an increase in blood volume and add pressure to the walls. arteries.
The answers is D because it needs something to survive
Answer:
<em>Geographic isolation</em>
Explanation:
Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.
The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.
