Variation is any difference in organisms of the same species, whereas gradualism is a microevolutionary theory.
<h3>What is a scientific theory?</h3>
A scientific theory is a given explanation on a phenomenon from the real world (e.g., the evolution theory).
The fossil record is a piece of evidence for the evolution theory (which is mainly based on natural selection).
In conclusion, variation is any difference in organisms of the same species, whereas gradualism is a microevolutionary theory.

Answer:
Produce and transport haploid gametes.
Explanation:
The reproductive system is a set of organs used to produce gametes and lead them outside the organism. Thus, this system is responsible for the production of gametes in the body of the animal or human, and in the case of male beings, their transfer to the body of the female in order to fertilize it and give way to reproduction, which is, in short, part of the tasks that every living being instinctively develops at some point in their life. The organs of the reproductive system are distinguished internally and externally. In humans, the external organ is the vagina for women and the penis for men, respectively.
Of the options listed, we can confirm that the best evidence to support the claim that global warming has a long-term impact on the ecosystem is given by the phrase "Habitat loss would occur, leading to a decline in species diversity".
<h3>How does habitat loss affect ecosystems?</h3>
- Habitat loss can decrease the species diversity in an ecosystem.
- This can have dire consequences.
- One such consequence is the <u>reduction </u>of primary consumers or producers.
- This decrease in food supply can cause the collapse of the food chain and the disappearance of the ecosystem as a whole.
Therefore, given that the increased temperatures will cause habitat loss, this will lead to a sharp decrease in biodiversity, meaning possibly fewer producers or primary consumers to maintain a stable food chain. This can lead to the full collapse of an ecosystem.

Answer:
Biotic
Because the acorn is abiotic.
abiotic factors are non-living physical parts of the environment that affect living organisms and the functioning of ecosystems.
I think the answer is B - a star! Hope this helps!
