Answer:
Letter E - exons are cut from the strand and removed
Explanation:
Letter A and B are incorrect because the poly-A tail and guanine cap are added to the 3’ and 5’ end respectively. They aid in translation of the mRNA, while serving as protection. The poly-A tail is repeated adenine nucleotides, while the guanine cap is a modified guanine nucleotide.
Letter C is incorrect because alternative splicing is one mechanism for generating variation, and is thought to be one of the reasons for why humans have smaller genomes than other organisms and still maintain high complexity. Alternative splicing is incredibly important because it produces more than one transcript from a pre-mRNA.
Letter D is incorrect because introns are the non coding portions of the mRNA. They are excised to make a smaller mRNA transcript, and one that contains all the protein genes.
This letter E is the correct answer, because exons are the coding portions of the mRNA, and are not excised during RNA processing.
Hope that helped! If I made a mistake, please let me know.

I may not be right but i believe the answer is c
Explanation:
the population goes down
Explanation:
Large algal beds die, depriving marine iguanas, turtles and many fish of their staple diet. Once weakened, strong swells and sea urchins break apart complex coral habitats that sustain diverse species changing the environment.
The energy role of a grizzly is that is is a omnivorous consumer because it is not a producer.
A grizzly bear's diet consist of both plants and animals as it relies on the food it eats for energy consuptions. It is incapable of producing energy with photosythesis, hence it is not a producer.
Answer:
Genotype
Explanation:
Genotype refers to the genetic constitution of an individual. It represents all the allele combinations of a particular gene or alleles of various genes present in the genome of the organisms and constitutes the genetic makeup of an individual. For instance, if an individual has I^A and I^B allele for ABO blood type, the genotype of the individual for the ABO blood type gene is "I^A I^B". Likewise, "TT" and "tt" represent the genotype of a pea plant having both the same type of alleles for the stem height gene.
