4. If you just finished exercising, what happens to the amount of carbon dioxide you<br> exhale?!
pentagon [3]

Answer:

More Carbon dioxide is removed from the blood and exhaled in the breath

Explanation:

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

Which statement explains the difference between a nerve that is connected to the skin and a nerve that is connected to a muscle?
Dahasolnce [82]

Answer: Hi! The answer you're looking for is:

"The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain."

When you receive, for example, a touch on your arm, the nerves connected to your skin transfer the information of this touch to your brain - in other words, it tells you how it felt. This touch would obviously be external, or outside of your body. Nerves connected to your muscles transfer information like how your muscles feel after hard exercise, or directions from your brain on how to move a muscle - I'm using my arm muscles and my finger muscles right now to type this answer for you! This would be internal.
