1. These four factors can effect ways evolution occur:

<span>1.) Mutation 
2.) selection
3.) Gene Flow
4.) Genetic Drift 

2.  </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.

Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors.

In population genetics, gene flow is the transfer of alleles or genes from one population to another.

<span>Genetic drift  is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>

Galina-37 [17]

Answer:

<h2>5.storage of energy</h2>

Explanation:

  • Proteins are important biomolecules that are a type of macromolecule.
  • This macromolecule is made up of a monomer that is called amino acid.
  • There are many functions of the protein molecules in living organisms.
  • They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
  • Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
  • Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
  • They also play an important role in the immune system.
  • The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.

How might a single base substitution in the sequence of a gene affect the amino acid sequence of a protein encoded by the gene,
vovangra [49]
The effect differs. It could produce a different amino acid in the sequence because the corresponding codon has changed. It could also prevent the production of the originally intended sequence by changing one of the amino acids of a "start" codon (aka AUG) or extend the protein's sequence by modifying a "stop" codon (UAA, UAG, UGA or UGG), producing a new protein that might be useless or have different effects on the cell.
