According to the cell theory, living things are composed of cells. Living things are capable of reproduction and two ducks can reproduce their own kind or their offspring starting from a single which was formed through the union of their reproductive cells. Now, the single cell formed still according to the cell theory has a capability to multiply itself to form as an offspring of the ducks.
Different cell types synthesize proteins at a different rate. Different cell types express particular genes at different levels. Different cell types receive different paracrine signals.
Lets say that there is an disease or infection on a certain species, if the community was not very diverse then that whole species will be effected because they are all alike. This can lead to an extinction of that species which then leads to the a possible collapse in the community due to the change in food webs.
More diversity equals to more stability because these risks have a fewer chance of happening.
I hope all of that makes sense(;
Bio=Life. So your answer is B-Biosphere.
Answer:
Glucose
Oxygen gas
Explanation:
Glucose is a non-metallic carbohydrate substance. It is the monomeric unit of the digestion of complex carbohydrate.
This compound is very important to all lives. The energy needed to power the activities in the body are derived from the compound.
It is made up of carbon, hydrogen and oxygen atoms.
Also, oxygen gas is used by animals for their metabolic processes. The gas combines with glucose to release chemical energy for use in the body. This molecule is purely made up of two atoms of oxygen that are covalently bonded together.
Anytime we breathe, we take in oxygen for use in our body
