Answer:
C). Mutations sometimes improve the chances of survival for a plant.
Explanation:
Within the genome of a cell, changes occurs in the nucleotide sequence of the gene from time to time. This change is referred to as MUTATION. It occurs via mistake during replication or induced by a mutation-causing substance (mutagen). Mutations are of different types and produce different results in the cell they occur. A common type of mutation is the SUBSTITUTION mutation, which is the kind of mutation where one or more nucleotide bases are replaced by another in the sequence.
Substitution mutation will change the amino acid sequence to produce either a protein that is same as the original, or different. The different protein can either be non-functional and therefore harmful or beneficial to the cell. For example, in a plant cell, the mutation can sometimes lead to a protein that confers resistance to certain environmental stresses on the plant cell. This MUTATION can be said to have improve the chances if survival of that plant. However, it does not always occur this way. It only happens sometimes.
