Which of these is true regarding prokaryotes?
a. it takes about 6-8 hours to duplicate dna
b. microtubules bind to the centromeres and pull the chromosomes apart
c. separated dna is attached to the cell membrane before the cell divides
d. the nucleus dissolves

c. Separated DNA is attached to the cell membrane before the cell divides.

Explanation:

The prokaryotes are single celled organisms. These are simple organisms which reproduce through asexual mode of reproduction that is cell division. They do not posses well define nucleus. Thus the genetic material remain in the cytoplasm of the cell. On cell division the genetic material (DNA) is distributed into halves for development of two daughter cells. Due to lack of nucleus and it's associated membrane the separated DNA get attach to the membrane before the cell actually divides.

it's the release of intestinal gas, which forms as a result of digesting food. when partially digested carbs reach the colon, bacteria convert part of that food into hydrogen and carbon dioxide gasses. you cant stop the stink, its a gas that comes naturally.
