I believe that phytoplankton is necessary to begin a food web
Answer:
Yes they do.
Explanation:
Both plant and animal cells contain ribosomes. Some may be found floating in the cytoplasm while others may be found in the rough Endoplasmic Reticulum.
The scheme of modern taxonomy goes:
Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species
So, a PHYLUM is made of several classes.
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!
