Answer 2
Answer:

Answer:

The correct answer is – the rate and depth of breathing increase during exercise.

Explanation:

There is an increase in physical activity during exercise. Muscle cells need to respire more than they usually do during rest. The heart rate increases which leads to the rate and depth of breathing increases so than the more oxygen is absorbed into the blood, and carbon dioxide is eliminated from the blood.  

Further explanation:

  • The most important organs of the body of an individual come into action during exercise are the heart and the lungs.
  • The lungs helps in bringing oxygen into the body, for energy which produce carbon dioxide as waste product and removes it.
  • The heart has to pump more blood so the oxygen reaches to the muscles that are doing the exercise.  
  • During exercise muscles work harder than usual, thus the body uses more oxygen and produces more carbon dioxide as a waste product.
  • Breathing has to increase from about when the person is resting, during exercise so it can supply the extra demand of oxygen and removal of extra carbon dioxide released in the blood.

A group of scientists are studying the effects of different fertilizers on the growth of pea plants. They began their study with 10 pea plants. They gave each plant a different type of fertilizer and tracked their growth over a period of 2 months. What’s the independent variable in this experiment? A. The plants B. The amount of fertilizer C. The growth of the plants D. The type of fertilizer

Answers

The answer is D. The type of fertilizer.

An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of fertilizer. So, the growth of pea plants is the dependent variable. Since different types of fertilizer affect the growth of pea plants, they are the independent variable.
