Which of the following is not true of phospholipid bilayers?
a. membrane budding requires transient breakages in the bilayer membrane.
b. the interior of phospholipid bilayers is a highly hydrophobic environment.
c. the chemical properties of phospholipids lead to the spontaneous formation of bilayers.
d. phospholipid bilayers separate the cell from the exterior environment as well as from compartments within the cell.

The correct answer is a. Membrane budding requires transient breakages in the bilayer membrane.

Explanation:

In the budding process of the membrane there are no breakages because the lipid membrane is so flexible that they start making the new bud and don't have to add or quit any phospholipid, and then when the process is done lipids separate and the membrane comes to the original assembly and the new bud is formed.

it has one origin of replication, but it proceeds in two directions - d)

materials water oxygen those are the things i can think of in this moment.
