Answer:

For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. ... Your circulatory system delivers oxygen-rich blood to your bones.

Which of the following best describes a benefit of one type of nonrenewable energy? (2 points)
KIM [24]
Natural gas and petroleum, upon burning, produce carbon dioxide. If you look at methane and the such, these hydrocarbons react with oxygen forming carbon dioxide and water.

The claim that petroleum is not carbon based is downright wrong. Methane is a hydrocarbon, and petroleum is a combination of complex hydrocarbons with varying chains of carbon atoms, some having 6 carbon atoms, others 60, giving it the viscous feel.

Coal deposits may be found in many places, but are still scarce and poses A LOT of risks, for example children were often harmed during the Industrial Revolution as a result of breathing in too much of the dirty air. Even now, coal mining is not without risk.

The only right answer then is the last one, where nuclear power does not produce air pollution. It relies on nuclear fission, where upon the splitting of uranium atoms they release energy, and this energy is harnessed by scientists for the betterment of all.

<u>Answer</u>: B.  Basic needs, such as food and water, will be scarce.

As the population increases, the resources necessary to feed the additional persons will also increase. However, basic resources such as food and water are not unlimited. Some countries have more and some less.

Thus, the amount of available drinking water will decrease as well as the available farmland. Due to more mouths to feed, food insecurity will increase as it is uncertain if it is possible to adequately feed the new population.

What would happen if another substance competed for the enzyme active site?
Lelu [443]
That's what is called competitive enzymatic regulation. If there are more of that substance than the enzyme substrate, then most of the enzyme, if not all depending on the substance's concentration, will be inhibited on its action. If there are more substrate then the competitive substance, the expected reaction for that enzyme will happen at an expected rate. If the ratio substrate:substance is 1:1 then the reaction enzyme-substrate is very slowed down.
