What happens to the carbon dioxide in the body?

It is taken to the lungs and expelled when we exhale ADDITIONALLY: While Oxygen is transported by red cells, CO2 is dissolved in the plasma. (the liquid part of the blood).

If you remember your basic chemistry, when CO2 is dissolved it produces carbonic acid, that's the stuff that makes carbonated drinks fizzy, and it can dissolve some minerals. SO... The body buffers the CO2 to keep from building up too much carbonic acid. When you hold your breath the body cannot expel the CO2 and your blood starts to become more acidic. THAT is the real reason you get the sensation that you MUST take a breath, your body is trying to expel the CO2. You can't detect low levels of oxygen nearly as well as you can detect high levels of CO2. If oxygen is removed from air and replaced with an inert gas, you won't notice it, you'll just go to sleep since the body can still expel the CO2.

Explain how your body uses chemical energy during exercise?

During exercise, your body uses chemical energy stored in molecules like glucose and fatty acids to produce ATP (adenosine triphosphate), which is the primary energy source for muscle contractions. This process occurs in your cells' mitochondria through aerobic metabolism. Additionally, your body can also utilize anaerobic metabolism to produce ATP quickly during intense exercise when oxygen supply is limited.

Which produces ATP molecules aerobic or aerobic respiration?

Aerobic respiration. Mitochondria are responsible for converting nutrients into the energy-yielding molecule adenosine triphosphate (ATP) to fuel the cell's activities. This function, known as aerobic respiration, is the reason mitochondria are frequently referred to as the powerhouse of the cell. Aerobic respiration.

These products may have side effects as diarrhea, increased heart rate, excessive sweating, nervousness, tremors, bulging eyes, etc.

Why does temperature increase during exercise?

The body temperature goes up because most of the energy (about 70%) that would power our muscles is lost as heat which heats us up.

See the related link for more information
Your muscle use lot of energy, when you exercise. Some of the energy can not be trapped by the muscles. This energy is released in the form of heat. So the temperature of your body rises.

an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.

What is the average time for a 22-year-old male to run one mile?

The record is just under 4 minutes, but not many men can run that fast! An athletic male should be able to do it in under six minutes. However, for the non-athletic or untrained male it could be nearer seven or even eight minutes. Depending on physical build, body fat, weight, health, stamina, practice and general fitness. For those who are not particularly athletic, running times can often be improved by a fitness regime and regular appropriate training. One month's good training can reduce an 8 minute mile to nearer six!

How many steps in a mile if your step is 32 inches long?

There are 5,280 feet in a mile, equivqlent to 63,360 inches. If your step is consistantly 32 inches, you would take 1980 steps. Solution: convert feet per mile to inches (5,280 X 12 = 63,360) and divide by number of inches per step (63,360 / 32 = 1980).

Why does your breathing rate change during exercise?

When you exercise the breathing rate increases because the body needs more oxygen to support your muscles. First off the heart rate increases which in turn speeds up how fast the air gets to the muscles or area being exercised then the oxygen is quickly used up then it needs to remove the by-product carbon dioxide which needs to be expelled quickly to allow more oxygen in.

How much weight do you lift in a lifetime?

Sound energy is transferred through vibrations in a medium, such as air, water, or a solid material.

How large can the Marasmius oreades grow?

depends on whether you want to know size of the fruiting body or the fairy ring itself (the mycelium). The fruits can reach a couple of inches in diameter for the cap and couple of inches in heights (average in the 1-2inches in both height and width, though usually slightly taller than wide). The fairy rings can reach considerable diameters (10-20ft, or larger) with enough time. Usually, the ring is disturbed or blocked by something before the maximum growth diameter is reached. Most I've seen personally only reach 2-3 ft in diameter, but I've seen a few as large as 5-6 feet across.

What factors would an athlete have to consider if he or she were training or competing at a high altitude location?

The theory behind high altitude athletic training is that since there is less oxygen present in high altitudes, athletes must train their bodies to be able to handle less oxygen by producing more red blood cells to carry the necessary oxygen. Oxygen is also depleted in the blood and muscles through strenuous activity. Therefore, by training at a high altitude, an athlete can expect to perform better at a lower altitude.
