which of the following outcomes would be most likely if the membrane of a cell were no longer selectively permeable?
o a harmful substances would be able to enter the cell and cause mutations to the cells dna
o b the cell would grow as more nutrients would be able to easily enter the cell.
o c a cell wall would form outside the membrane to protect the contents of the cell
o d the cell would die as it would not be able to regulate which substances could enter and leave.

Explanation:

The selective - permeability of the cell membrane is crucial for maintaining the cell's internal environment by regulating the entry and exit of substances. Without it, the cell cannot control what enters and leaves, leading to an imbalance that is fatal to the cell. Option a only focuses on harmful substances causing mutations, not the overall impact. Option b ignores the potential entry of harmful substances. Option c is incorrect as the cell wall formation is not a response to loss of membrane selectivity.

Answer:

D. The cell would die as it would not be able to regulate which substances could enter and leave.
