Which of the following is not associated with the large absorptive surface of the small intestine? a)circular folds (plicae circulares) b)intestinal length c)microvilli d)villi e)rugae

The circular folds slow the passage of the partly digested food along the intestines, and afford an increased surface for absorption. They are covered with small finger-like projections called villi (singular, villus). Each villus, in turn, is covered with microvilli.

While rugae is only evident when an organ or tissue deflares or relaxes. The rugae unfolds for increase in volume . Plicae remains folded in the intestinal walls.

Rugae is not associated with the large absorptive surfaces in the small intestine.

is in the form atp or adenosine triphosphate

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
