Darwin observed that organisms that were best able to survive and reproduce had adaptations that were...
11111nata11111 [884]

Answer:

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

Hope this helped!

In a soft-bottomed intertidal community, oxygen would be most plentiful for meiofauna in which type of bottom?
Sonbull [250]

Answer:

The options are:

A. Gravel

B. Sand

C. Silt

D. Clay

The answer is A. Gravel

Explanation:

Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.

Gravel aren’t tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
