Hello there! The answer is A trait that helps an organism survive and reproduce in its environment.

An adaptation is something an animal develops naturally to better live in its environment, making A your best option.

It's not B or D because adaptations are the animal's changes, not the environment. It's not C because although how they obtain food may be part of it, it is not the full thing.

I hope this was helpful and answered your question, have a great rest of your day!

The first one is correct because all of the other definitions give an example of a change in the environment not the animal in question.

According to the phylogenetic tree, which domains are more genetically related?

LUCKY_DIMON [66]

The answer depends on the interpretation and understanding of the phylogenetic trees. The image shows the rooted phylogenetic tree consisting of the various kinds of organisms. The rooting of the tree is done by looking at how closely two species are related to each other. The species within a larger branch or archae are more similar to each other than with the species of the eukarya branch. The distance between the different branches of the tree also indicate how different they are. Larger the distance, the less related they become.
