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.
Carbon because in the carbon cycle it’s recycled by plants and animals continuously in the atmosphere where it can also turn into organic carbon in the ground.
