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.

Answer:
Capillary action
Explanation:
Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it's way all the way up to the branches and leaves. Read on to learn more about how this movement of water takes place.
There are many benefits provided by biodiversity. It can be in our biological resources, ecosystem services and also social benefits. The three social benefits provided by biodiversity would be the following:
1. Research, education and monitoring
2. Recreation & tourism
3. Cultural values
Explanation:
Biodiversity is “the variability among existing animals from all causes including temporal, marine and other aquatic ecosystems, and the environmental complex.
Pollinators, including bees and butterflies, contribute meaningful environmental and economic advantages to agricultural and essential ecosystems, including adding heterogeneity and productivity to food crops. As many as one-third of the world's food production relies directly or indirectly on insect pollination.
Answer:
Well...
Explanation:First of all skin color is determined by how much melanin you have and the one thing that would show more variability in the human population is probably the one that uses less genes, because of how we come from only two genes which makes us different.
