Bottleneck is an example of a genetic drift that happens when the size of a population is severely reduced.
The answer is a population.
Goods or services that are required.
Genetic variation is advantageous because it enables some individuals and, therefore, a population, to survive despite a changing environment.
Answer:
The correct answer will be- the planets and moon also exhibit hydrothermal vents, volcanoes and rocks.
Explanation:
Scientists have always tried to understand and explain the origin of life on Earth and predicted that life on earth originated as a result of the conditions created by the distance of the Earth from the Sun.
Later discoveries found that life exists even in the harsh conditions on Earth-like hydrothermal vents and inside sub-surface of the rocks. This shows that life can exist in extreme conditions.
Since the planets other than Earth posses such hydrothermal vents, rocks and volcanoes, therefore scientists predict that life could be found on other planets.
