Answer:
moon
Explanation:
a guess but i'm pretty sure because they study the mostly things on earth
It will pinch nerves aka the spinal cord so the result is to be paralyzed usually although sometimes its only temporary
Answer:
<u>Living organisms need to maintain homeostasis constantly in order to properly grow, work, and survive.</u>
In general, homeostasis is essential for normal cell function, and overall balance. For this process to function properly, homeostasis helps our body to keep both water and salt balance level.
Have a good day! :D
Answer:
1.—The (more) variations in forms it can produce.
2.—Biologists often need to search for evidence (in the distant past).
3.—By revealing the forms of (extinct species).
4.— (Intermediate) fossils can help biologists.....
Answer:
Genetic diversity in a small population, with a high level of genetic drift and with very little migration will decrease because existing alleles will be lost and few new alleles will be introduced over time (option A).
Explanation:
Evolution - linked to the natural selection and perpetuation of a species - depends, in large part, on three fundamental factors to make it happen:
- Mutations
.
- Genetic drifts.
- Migrations.
In small and isolated populations, very little genetic variation, high levels of genetic drift and very few mutations can be observed, which could lead to some alleles being lost and the species may become extinct.
Genetic drift (GD) is an important factor in terms of natural selection, as it is the result of allelic variations that occur from one generation to another. In large populations, GD is low, given the cross between different individuals is greater. A characteristic of GD in small populations is that their levels are very high, and this leads to the eventual loss of alleles.
In this small population, without the possibility of migration -few new alelles will be introduced- genetic variation will decrease, due the genetic flow is low, reducing reproductive fitness and weakening the population's resistance to environmental changes, which could result in the long-term extinction of the species.
