Explanation:
Sophie is wrong because although dolphins and sharks can technically be said to be similar, it resulted from convergent evolution, which has nothing to do with common ancestry and rather to do with similar environments for their homes.
Answer:
1) A
2) Could be A, B, or D
Explanation:
1) Prokaryote is a single celled organism that has no distinct nucleus, membrane - bound organelles, and specialized organelles (such as the mitochondria).
This definition would only match A) a bacteria cell because all the other cells are called Eukaryotas (which are more complex and have membrane - bound organelles).
2) The answer could be A because Prokaryotic cells lack membrane bound organelles
The answer could be B because the diagram has labeled the cell membrane as "plasma membrane"
The answer could NOT be C because Prokaryotic cells do not have nucleus's, but have free floating DNA.
The answer could be D because it is the only image that has a flagellum (which helps the cell move)

Question: If they aren't hermaphrodites, can they still be male and female at the same time?
Facts: Different snails reproduce differently, but most snails are "hermaphrodites." Being a hermaphrodite means that any given snail can be both male and female at the same time. This can make it a lot easier for snails to reproduce and quickly make a whole lot of snails! Some hermaphrodite snails do not need another snail to reproduce, but can make more snails all by themselves (this is called asexual reproduction). Other snails are hermaphrodites but still need another snail to reproduce (this is called sexual reproduction). There are also some snails that aren't hermaphrodites, but are either male or female, and must find a snail of the opposite sex to breed with.
