<u>Answer:</u>
The Earth has got its tilted axis and this is the reason for different seasons to be formed. Communities are a set of population found in that particular area and are of two types.
A) Terrestrial (Land)
B) Aquatic (Water).
These communities to flourish need a perfect environment with a perfect season. Hence according to the season formed due to the tilted axis influences the terrestrial community which forms in that particular region and have the ability for the region specific community growth.
The terrestrial community of a tundra or desert or rain forest all depends on the particular season that can be formed due to the position of the earth facing the sun.
In accordance with evolutionary theory, male aggression and competition as well as female nurturing develop in childhood as a precursor to their adult responsibilities.
<h3>What is the theory of evolution?</h3>
Within the framework of evolutionary theory, the genesis of the human species is looked at.
According to this theory, people in the current world have qualities that have been passed down through the generations that have been genetically affected and have aided in successful reproduction.
<h3>What key principles guide evolutionary theory?</h3>
According to Darwin's Theory of Evolution, individuals within a species are not all alike, characteristics are passed down through generations, more offspring are born than can live, and only the survivors of the competition for resources will reproduce.

Ozone is produced naturally in the stratosphere. But this "good" ozone is gradually being destroyed by man-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These substances were formerly used and sometimes still are used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants. Once released into the air these ozone-depleting substances degrade very slowly. In fact, they can remain intact for years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun's UV rays and release chlorine and bromine molecules, which destroy the "good" ozone. Scientists estimate that one chlorine atom can destroy 100,000 "good" ozone molecules.

Answer:
The correct option is 'the ability to absorb other cells gave some prokaryotes a survival advantage.'
Explanation:
The scientists have brought forward the theory of endosymbiosis which explains how eukaryotic cells evolved from prokaryotic cells. According to this theory, the scientists claim that the organelles found today in the cells, once existed as individual prokaryotic cells. These organelles were engulfed by larger prokaryotic cells with time and hence, the eukaryotic cells evolved from these prokaryotic cells. The larger prokaryotes might have engulfed the smaller cells for survival.
