Answer:
It would most likely kill the cell.
Explanation:
If a cell's membrane is fully permeable (not semi-permeable) then substances that are harmful to the cell are more than likely to enter it at one point or another, which can pretty much end up killing it.
In short, the semi-permeable membrane is there to ensure that only the useful stuff gets in and that the bad stuff stays out.
Answer:
2. Hip bones
Explanation:
More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.
Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.
