The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow? (highlight the correct answer. The narrowing of blood vessels increases pressure and leads to faster blood flow.

High blood viscosity increases the resistance in the blood vessels and leads to slower blood flow.

Low blood pH decreases the rate of diffusion through the blood vessels and leads to slower blood flow.

The changing of the shape of red blood cells to a crescent shape decreases resistance and leads to faster blood flow.

High blood viscosity increases the resistance in the blood vessels and leads to slower blood flow.

Explanation:

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
