Question

which of the following is generally true within the human body? blood flow near the skin and in the extremities only increases when a person is in a state of heat stroke. when a person is warm, blood flow near the skin and in the extremities increases. when a person is cold, blood flow near the skin and in the extremities increases. a person having a heat stroke has constant blood flow through the heart, but decreased blood flow near the skin and in the extremities. part f having a low - grade fever of 100° to 102°f is a common side effect of a bacterial infection. which of the following statements provides the most reasonable explanation for why this could be beneficial? an increase in body temperature causes the bacteria to multiply faster within the body, but they do less damage at the higher temperature. it is doubtful that a change in body temperature would have any effect on the bacteria living inside the body. an increase in body temperature causes enzymes to break down more substrate. an increase in body temperature could denature enzymes in heat - sensitive bacteria without denaturing the enzymes of the person with the infection.

Explanation:

For the first question, when a person is warm, the body tries to dissipate heat. One way is by increasing blood flow near the skin and in the extremities to release heat to the environment. For the second question, an increase in body - temperature can denature enzymes in heat - sensitive bacteria while the enzymes of the infected person can still function, which helps in fighting the infection.

Answer:

First question: When a person is warm, blood flow near the skin and in the extremities increases.
Second question: An increase in body temperature could denature enzymes in heat - sensitive bacteria without denaturing the enzymes of the person with the infection.
