Vitamin D can be obtained from food and supplements, or synthesized by our bodies when we receive UV radiation in our skin, which is our major source.

Capillary action<span> occurs when the </span>adhesion<span> to the walls is stronger than the </span>cohesive<span> forces between the liquid molecules.</span>
Bacteria multiply. I think... bacteria dont have double helix dna. They have what is called a plasmid. If I remember correctly, its most often bacteria that have plasmids for dna and so they duplicate by binary fission instead of the way we do.
