Answer/Explanation:
<u>Darwin's</u> <u>theory </u>of evolution refers to how the characteristics and features of a species can change over time. The process of evolution occurs due to <u>natural selection</u>. Natural selection is the mechanism by which organisms that have inherited beneficial traits are more likely to survive and undergo <u>successful reproduction</u>, meaning that variation is passed on to the next generation.
For example, in a species that suffers from overpopulation, organisms will likely have to compete for food and might <u>struggle to survive.</u> However, if a random change in the DNA sequence occurs, it could provide a beneficial effect to an organism that makes it more likely to find food and outcompete others. This makes that individual more likely to survive and reach mating age. This i<u>nheritable variation</u> could then be passed on to that individual's offspring.
Answer:organisms that happen to share a common trait, even though they evolved
Explanation: polyphyletic groups have similar characteristics but
that have been grouped together
They do not share an immediate common ancestor.
Mitosis is a cell division that occurs in the nucleus of a cell. Mitosis is 2 cells, called daughter cells, that are genetically identically to the original cell.
