Answer:
Divergence
Explanation:
This happens because of the different genetic makeup or genotype of different individuals. The divergence mechanism occurs because of divergent evolution where in some cases random chances occurs and neurons became a source of stimulus for one but not other and vice versa.
When using the term 'life form' I assume you are speaking of animals, bacteria, etc. Scientists take years to find their desired conclusion because of how the environment tends to change quite frequently (Depending on where the creature lives). The earth is constantly revolving and rotating, which causes changes in the environment. These changes affect the animals behavior, eating habits, and overall chances of survival. A factor that must also be considered is that scientists have to examine these creatures in their natural habitat which can be an issue depending on where they live. For example, if I were to study the behavioral patterns of a Leopard, it would be extremely difficult to do so because the Leopards are specifically keen at camouflaging in their environment. That would make observing its behavioral patterns very frustrating and time consuming. In a way, mother nature is always against us.

Answer: The correct option is D.
All of the above.
Explanation:
This is because complex organisms developed from cyanobacteria and release of oxygen. Cyanobacteria is a blue green algae and first organism that photosynthesized. It uses carbondioxide and water in the presence of the chlorophyll present and light energy to produce carbohydrates and oxygen. The oxygen released into the atmosphere brought about respiration and development of ozone.
This great oxidation event changed the Earth and life on Earth too.
Answer: Water
Fats are a subgroup of compounds known as lipids that are found in the body and have the general property of being hydrophobic (meaning they are insoluble in water)
water refers to a chemical substance consisting of two hydrogen atoms attached to the central oxygen atom via a covalent bond.
