The 4 factors affect evolution, according to Darwin’s Origin
of Species are;
Variation
Heritability
Competition
Differential survival
Variation ensures that
there is variability of population traits
on which selection pressures will apply.
Heritability means that the traits must be able to be passed down to offsprings through gametes.
Competition occurs when the individuals in the population compete for limited resources
Differential survival
occurs due to competition for resources
and other selection pressures. This result
to the survival of the strongest and weeding
out of the weak from the population.
Answer:
<h2>
The Nucleus.</h2>
Explanation:
The structure most necessary for a mitochondria to produce new cells is the nucleus.
The nucleus is a very specialized structure that occurs in most cells including the mitochondria.
It is a membrane bound organelle that contains genetic materials which is the DNA of all eukaryotic organisms(multicellular organisms)
It plays important functions such as:
1. Primarily an information center of the cell
2.Metabolism roles
3. Growth and production of new molecules in the mitochondria(mitochondrial bio-genesis).
Alleles can disappear from a population through natural selection. This relates to the most fit phenotype because the breed with the desirable trait, or the most fit, will live and produce off spring. Eventually the less desirable trait and its corresponding allele will disappear after multiple generations pass. If the environment does not change alleles of non desirable traits will disappear. <span />
