Question

Life processes require a way to protect fragile biological systems from the harsh physical and chemical properties of their environments. Cells achieve this by creating boundaries so that processes can take place without interference from the surroundings. This partitioning separates highly organized compartments of low entropy (the interior of cells) from disorganized regions of high entropy (the environment), while still permitting the exchange of nutrients and waste (Figure 2.40). Because the solvent of life on Earth is water, such selective barriers need to partition aqueous compartments, which is best done using nonpolar components with hydrophobic properties. These physical barriers in living systems are biological membranes.

Explanation / Answer

The answer to 1st question is option A

Amphipathic means cell membrane has both hydrophilic and hydrophobic ends

The answer to 2nd questiion is option D

Detergent has hydrophilic and hydrophobic ends like molecules present in cell membrane
