Function.
Explanation:
The cristae greatly increase the surface area of the inner membrane on which the above-mentioned reactions may take place. A widely accepted hypothesis for the function of the cristae is that the high surface area allows an increased capacity for ATP generation.

B.Human activities and natural events can damage the environment.,
C.Natural events always have a positive impact on the environment.,
D.All human activities change the environment in a negative way.
Answer:
B. Human activities and natural events can damage the environment.,
Explanation:
Human activities are those activities carried out by a human being. The environment is being degraded daily as a result of the activities of man as well as natural occurrences e.g earthquake, tsunami, wild fire etc.
Human activities also called anthropogenic activities that damage the environment include sewage pollution, burning of fossil fuels, oil spillage etc. Hence, according to this question, human activities and natural events can damage the environment.

False its faster! Hope this helps! More information here! Answer: An area going through secondary succession reaches its climax community faster because the area begins with some soil and some plant and animal species. An area that goes through primary succession, on the other hand, begins with no soil and no organisms, so reaching the climax community takes longer.

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.

difference between parallel venation and reticulate venation
this is where you can get
The difference between parallel venation and reticulate venation is in parallel venation, the vein of the leaf blade is in a parallel pattern, and in reticulate the vein of the leaf blade is a net or web-like structure.
What is venation?Venation is the pattern of veins present in the leaves. There are different patterns of veins present in the leaves, parallel venation, for example, banana leaf, and reticulate venation, for example, papaya leaf.
Thus, In contrast to reticulate venation, where the vein of the leaf blade is arranged in a net-like pattern, parallel venation has the vein of the leaf blade arranged in a parallel pattern.

Why do you think analogous structures would cause Evolutionary biologists problems when trying to determine the relatedness of certain species?
Answer: Two analogous structures are similar in phenotype and developed to perform the same function, despite not being inherited from a common ancestor. As so unrelated species may look related due to having analogous structures.
Explanation:
Analogous structures evolved due to Convergent evolution. It means that structures are similar in functions but differ in morphology.
What do you mean by Species?A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
Analogous structures are similar in structure that evolved independently in two living organisms to serve the same purpose. Due to their approx similarity sometimes evolutionary biologists face problems when trying to determine the genetic relatedness of certain species.
Therefore, Analogous structures evolved due to Convergent evolution. It means that structures are similar in functions but differ in morphology.
