First answer is correct. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.

Answer:
lysosomes
Containing acid and several types of digestive enzymes, lysosomes digest unwanted organelles in a process termed autophagy, from the Greek words for “self” and “eat.” The multipurpose lysosome also processes proteins, bacteria and other “food” the cell has engulfed.
The plasma membrane is composed of the phospholipid bilayer. The phosphilipids have one head and two tails. The head is polar (hydrophilic) as the tail is non-polar (hydrophobic).
