A cell membrane is a phospholipid bilayer. Which major benefit does the arrangement of lipids in the membrane provide to a cell?

a. The surfaces of the membrane can interact with water solutions.

b. The surfaces of the membrane are nonpermeable.

c. The bilayer makes the cell strong and rigid.

d. The phospholipids help the cell easily change size.

b. The surfaces of the membrane are nonpermeable.

Explanation:

This helps the cell membrane to protect the cell.

The surfaces of the membrane can interact with water solutions.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
