Answer:

C. R group

Explanation:

Amino acids are the monomers for proteins. Various amino acids are joined together by peptide bonds to form polypeptides.

All standard amino acids have a central chiral carbon atom to which four functional grouped are bonded. All the amino acids have one carboxyl group, one amino group and one hydrogen atom bonded to the central carbon atom.

However, the chemical nature of the "R group" differentiates various amino acids. For example, alanine has a "CH3" group as an R group while glycine has one more hydrogen atom as its R group.

klasskru [66]

Answer:

Mutation

Explanation:

Mutation is a change in the nucleotide sequence by addition, deletion, substitution, etc which results in the slow addition of allelic variation that increases the diversity in a population and leads to evolutionary change.

The right mutation in the allele or gene is favored by nature and it is passed in the next generation through reproduction. Mutation helps in the survival of a population in the continuously changing environment by adding new alleles that increase the fitness of the organism. So the correct answer is mutation.

What encourages flooding by allowing water to run off into streams?
expeople1 [14]

Deforestation encourages flooding by allowing water to run off into streams

<u>Explanation</u>:

Deforestation plays vital roles in the flooding. The roots of the Trees prevent sediment runoffs and forests hold more water than farms or grasslands.Firstly the leaves in the trees will capture some amounts of water which will be eventually evaporated. Secondly, some quantity of water is  absorbed by the tree's roots. Also,Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream..

The process of deforestation will lead to dislodging of the topsoil. this makes the  topsoil unstable and reduces its capacity to hold down the water
