Answer:

Carbon pools are reservoirs of carbon that have the capacity to both take in and release carbon.There are four very broad global carbon pools which encompass many complex systems which will be discussed on this page. Each of these pools exchange carbon with one another, known as carbon fluxes, comprising what is known as the global carbon cycle.

Answer: when their is a new moon

Explanation:

Total solar eclipses happen when the Moon completely covers the Sun, and it can only take place when the Moon is near perigee, the point of the Moon's orbit closest to Earth. You can only see a total solar eclipse if you're in the path where the Moon casts its darkest shadow, the umbra.

Answer:

The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.

Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.

Explanation:

shivering burns fat to help keep one warm

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Answer: C: an increase in the number of fish caught from the lake

Explanation:

An increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.

Carbon dioxide can have both direct and indirect effects on a lake's ecosystem. Here are some of the effects:

Acidification: When carbon dioxide dissolves in water, it forms carbonic acid, which can lower the pH of the water.

Oxygen depletion: If carbon dioxide levels are too high, it can lead to oxygen depletion in the water.

Algal blooms: High levels of carbon dioxide can also stimulate the growth of algae in the water. This can result in algal blooms, which can have negative effects on the lake ecosystem, such as oxygen depletion, fish kills, and changes in water clarity.

Thus, an increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.

Answer:

B

Explanation:

Answer:

All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.
