Question

Hookworms live in the human intestine, drinking the blood it sucks from the intestinal wall. The chart contains data on the number of hookworms and the amount of blood loss caused by a particular number of worms. What is the dependent variable?

a) Number of Hookworms
b) Amount of Blood Loss
c) Human Intestine
d) Drinking Behavior

Answer 1

The dependent variable in the chart regarding hookworms and the blood loss they cause is the Amount of Blood Loss, as it is the effect being measured based on the number of hookworms present.

Step-by-step explanation:

In the context of the chart provided regarding hookworms and the blood loss they cause, the dependent variable is (b) Amount of Blood Loss. This is because the dependent variable is the outcome or effect that is being measured, which in this case is the amount of blood the host is losing, and it is expected to change in response to the number of hookworms present in the human intestine. The number of hookworms, on the other hand, is the independent variable as it is the factor that is being manipulated or varied to observe the effect on the dependent variable.
