question 43 (1 point)
rabies is caused by the bite of an infected animal.
true
false

Explanation:

Question 1 (Lyme disease):

Lyme disease is transmitted by the bite of infected black - legged ticks (deer ticks), not by ingesting dirty water. So the statement is false.

Histamine and kinins are chemical mediators of inflammation. They cause vasodilation (which increases blood flow) and also increase capillary permeability, allowing fluid and immune cells to move into the affected area. So the statement is true.

Rabies virus is usually transmitted to humans through the bite of an infected animal (such as dogs, bats, etc.). The virus is present in the saliva of the infected animal, and a bite can introduce the virus into the human body. So the statement is true.
