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.
I believe the correct answer from the choices listed above is option D. Sandstone and basalt can be changed by heat and pressure to form metamorphic rocks. They <span>are </span>formed<span> when </span>rocks<span> are close to some molten magma, and so get heated up. Hope this answers the question.</span>
UV light could change the DNA of the skin cells of the organism, possibly causing cancer cells to form.
