Answer:
C. They have a greater surface-to-volume ratio.
Explanation:
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.
Enzymes are biological catalysts.They lower the activation energy necessary for the reaction to occur, and that makes the chemical reactions quicker in living cells.
Pressure tightness and squeezing
This can cause mutations, these mutations can be helpful,harmless or they can be harmful.
