3 0

Answer:

Essential to the formation of all known life, evidence of stable liquid water elsewhere could indicate an environment beyond Earth that could sustain the formation of extraterrestrial life

Answer:

<u>the bottleneck effect</u>

<u />

Explanation:

Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.

Some mutations or alleles may become extinct from the population.

<u />

Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other  phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.

Liono4ka [1.6K]

Answer:

The correct answer would be the slide should be almost in focus when changing to higher magnifications.

A parfocal lens is a type of lens which stays in focus when focal length or magnification is changed.

Parfocal microscopes are those in which objectives remain in focus even when magnification is changed for example, when it is switched from 10x to 40x, the object or slide remains at the focus.
