The question above is written twice, and without options attached. For comprehension, I would re-write the question with the options attached

Each of the following changes will result in increased blood flow to a tissue except

a. increased vessel diameter.

b. increased blood pressure

c. relaxation of precapillary sphincters

d. increased hematocrit

e. decreased peripheral resistance.

The correct answer is Option D (increased hematocrit)

Explanation:

An increase in vessel diameter would lower resistance, thereby increasing blood flow to the tissue.

An increase in blood pressure would increase blood flow to a tissue. This statement is true provided the blood pressure taking blood to tissue is not increased in the arteries.

The relaxation of precapillary sphincters which regulate the flow of blood through capillaries would cause increased blood flow to a tissue.

A decreased peripheral resistance, which means a decrease in resistance of the arteries to blood flow would increase blood flow to a tissue.

While increased hematocrit means increased red blood cells in the total volume of blood causing more thickened blood resulting in reduced blood flow to a tissue.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
