Answer:
D
Explanation:
Intestinal cell takes in glucose against Concentration gradient (uses energy in the form of ATP) to transport glucose into cell.
In blood cell, uptake of glucose occurs down concentration gradient. Hence, its facilitated diffusion (passive transport)
Glucose is a polar molecules due to presence of polar hydrophilic - OH group, hence carrier proteins are needed to provide a hydrophilic channel for glucose to enter the cell via facilitated diffusion.
The major difference between viruses and living things are that most living things can reproduce independently, whereas viruses must infect living cells in order to reproduce. The correct answer is C.
