Answer:
a. Blood vessels are constricting causing greater peripheral resistance.
Explanation:
Peripheral vascular resistance means the resistance in the circulatory system that is used to control blood pressure and the flow of blood. When blood vessels constrict, there would be an increase in systemic vascular resistance. When blood vessels dilate, there would be a decrease in systemic vascular resistance.
Answer:
If the fluid is very concentrated, the cell will lose a lot of water, causing the red blood cell to shrink and die. On the opposite side of things, if the body fluids are too dilute (hypotonic), water will diffuse into the red blood cells (because the inside is more concentrated than the body fluid), causing the cells to burst open.
There are many species that might go extinct. The one most endangered: White rhinos, with less than 100 in their population. To help these animals, people fund programs like the WildLife foundation. Today, with technology, we haven't had the time to make a change, these people work hard to make sure these animals get proper care and love. :)
Hope that helps!
