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.

Answer:
the Grey line is the expect change and is where the temperature should be
Explanation:
the black line is where the temperature is and how much the temperature can fluctuate while still allowing the organism to live and do so comfortably
Answer:
Natural selection will favor red deer that produce a dozen or more offspring that survive for at least a year.
Explanation:
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
Natural selection is the result between the individual phenotype and the environment that determines the destiny of genes. It is the differential capability of individuals to leave offspring.
Aptitude (or fitness) is the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.
Natural selection, eventually, will favor red deer that produce a dozen or more offspring that survive for at least a year. These animals have more chances of leaving fertile descendants that will be able to grow, develop, survive, and reproduce. They have a higher aptitude than those individuals that only have four fawns during their lifetimes. These animals have fewer probabilities of leaving survival descendants able to reproduce.
