Answer:
B. introns; exons
Explanation:
Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.

Answer:
Explanation:
In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.
 mitochondria has two membrane, 
It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration. 
The folds also enables a large surface area that makes chemical process to occur in an efficient way.
