Question

EXPLAIN YOUR ANSWER!!!

Which of the following outcomes would be most likely if the membrane of a cell were no longer selectively permeable? (2 points)


Harmful substances would be able to enter the cell and cause mutations to the cell's DNA.
The cell would die as it would not be able to regulate which substances could enter and leave.
A cell wall would form outside the membrane to protect the contents of the cell.
The cell would grow as more nutrients would be able to easily enter the cell.

Answer 1

If the membrane of a cell were no longer selectively permeable then "The cell would die as it would not be able to regulate which substances could enter and leave", since a selectively permeable membrane allows both things to enter and leave for the cell's survival.
