The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.
Explanation:
In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.
This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.

Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.
I believe that the answer is A, if I am not mistaken!
