Answer:

The protein products of proto-oncogenes regulate the processes of cell division and growth.

Explanation:

The proto-oncogenes are the genes that code for the proteins involved in the regulation of cell division, growth, and differentiation. Certain mutations in these proto-oncogenes transform them into the oncogenes.

For example, the "erbB" gene code for receptor of epidermal growth factor which in turn regulates cell division in epidermal cells. The mutated erbB oncogene code for truncated receptor for epidermal growth factor which in turn makes the cell to divide continuously.

Hence, the proto-oncogenes are required by cells to regulate the processes of cell cycle, growth, and differentiation.

What does it mean to be selectively or semi-permeable
vova2212 [387]

Answer:

Selectively permeable or semipermeable means specific substances are allowed to pass through the plasma membrane.

Explanation:

The plasma membrane is selectively or semipermeable in nature because the plasma membrane allow only specific molecules such as nonpolar substances or hydrophobic substances such as steroidshormone to pass through it and prevent the passage of polar solute molecules such as water,glucose.

   To transport these polar solutes across the membrane an additional protein is needed in case of transport of water channel protein is needed whereas in case of glucose transport carrier protein is required.
