Answer:
Provide nutrients to interneurons
Explanation:
The four main functions of glial cells are: to surround neurons and hold them in place, to supply nutrients and oxygen to neurons, to insulate one neuron from another, and to destroy and remove the carcasses of dead neurons.
Is there a picture that goes along with this question?
The most important thing is to try and extinguish a fire if a fire extinguisher is near. If not, they second most important thing is to rush out of the lab using the fire escape route and call the local fire department which will then handle the situation.
During the day, due to the presence of sunlight, the process of photosynthesis peaks over that of respiration. Photosynthesis uses carbon dioxide to make carbohydrates releasing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis drops. This, therefore, causes the rate of respiration to surpasses the rate of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is released.
<u>ANSWER</u>:- option A formation of fossil fuels.
<u>Explanation</u>:-
- Fossil fuels are formed from dead and decaying plants and animal.
- When the dead and decaying plants and animals are exposed to heat and pressure over a long period of time they get converted to oil, coal, gas etc.
- These oil ,coal, gas are called as fossil fuels.
- The entire process of formation of fossil fuels can take place over a million of years.
- In contrast to the formation of fossil fuels , the process of photosynthesis in plants, respiration in animals and emission of waste is a phenomena which occurs at daily basis and over a short interval of time.
So, <em>the formation of fossil fuels is the phenomena which takes the longest time in the carbon cycle.</em>
