Answer:
hi and its carbon im taking a quiz over it aswell
Explanation:
Proteins and complex carbohydrates are part of the four major macromolecular groups and play crucial roles in our body functions and energy provision. They are essential in our diet, assisting in maintaining connective tissue, aiding blood clotting, and providing energy for our bodies.
Proteins and complex carbohydrates are both part of the four major macromolecular groups, which also involve lipids and nucleic acids. These macromolecules are vital to the human diet, providing fuel for the body, and undergo digestion and energy production processes. Carbohydrates can be both complex, like starch and glycogen or simple sugars like glucose and fructose. These sugars are key contributions to ATP production in cells, and glucose specifically, is controlled by a variety of endocrine mechanisms to regulate its presence in the bloodstream. The excess glucose is stored as glycogen in the liver and skeletal muscles, or instead transformed into fat in adipocytes.
Proteins along with carbohydrates are also essential in the maintenance of connective tissue and assisting in blood clotting. This prominence of these macromolecules in the diet is why athletes often 'carb-load' before engaging in major competitions, allowing their bodies to possess enough energy to compete at such high levels. Foods like grains, fruits, and vegetables are all natural carbohydrate sources, providing us with the glucose our bodies require. Therefore, proteins and complex carbohydrates showcase inherent essentiality within the human diet, playing significant roles in body function and providing necessary energy for activities.

b. speciation
c. convergent selection
d. stabilizing selection
Speciation occurs when a population suffers divergence. Genetic flow is interrupted between the new groups that keep reproducing and going through mutations. Reproductive isolation emerges. Option B. Speciation.
Occurs when the original population is divided into two or more groups and each group is exposed to different environments.
Each group reproduces for many generations, going through many changes or mutations.
These changes will depend on each group's environment and its ecological pressures.
Pressures act on individuals and make them adapt to the new environmental conditions.
Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce.
The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.
There are different types of speciation. One of them is Allopatric speciation.
Allopatric speciation refers to the geographical separation of a continuous genetic population, originating two or more new geographicallyisolated groups.
During these events of speciation, emerging new barriers impede genetic flow between groups. The two new populations that are separated can not get together and mate anymore.
These barriers might be geographical or ecological.
After the emergence of the barrier, the two populations evolved separately in different new species.
Two different species that evolved in allopatry might meet again in secondary contact if the barrier that separated them, disappears. However, they will not be able to mate and reproduce due to prezygotic and postzygotic reproductiveisolation.
The exposed example is a case of speciation, in which the chimpanzees' habitat was fragmented and a town was built.
The town acts as the barrier between the two diverged groups, impeding them to meet.
Genetic flow is interrupted and each group keeps reproducing separately, and mutating, leading to genetic changes and reproductive isolation.
After a long period of time, the chimpanzees came back into contact but were incapable of breeding.
This process is speciation. Option B.

Answer:
In some communities, the phenomenon of competition can easily be depicted as compared to other communities. In some communities, there will be enough resources available and hence, these communities will have a fewer competition to be recognized. In other cases, some communities might require evolutionary changes to occur for the depiction of a competition. In such scenarios, it will be difficult to recognize competition at the time of its existence.
