Question

Microvilli greatly increase the efficiency of nutrient uptake in the small intestines. How do the size and shape of microvilli promote this efficiency? a. They have a greater surface area-to-volume ratio than larger cells. The finger-like projection shape provides more surface area over the small intestines from which they absorb nutrients and contains blood vessels so nutrients passing through them can enter the bloodstream readily. b. They have a greater surface area-to-volume ratio than larger cells. The finger-like projection shape is present in the middle of microvilli, which have more surface area over the small intestines from which they absorb nutrients and also contains blood vessels so nutrients can enter the blood easily. c. They have a greater surface area-to-volume ratio than larger cells. The finger-like projections prevent large particles of food from passing through the digestive system and also contain blood vessels so nutrients passed through them can readily enter the bloodstream. d. They have a greater surface area-to-volume ratio than larger cells. The finger-like projections aid in mechanical digestion of food particles and contain blood vessels so nutrients passing through them can enter the bloodstream readily.

a. They have a greater surface area-to-volume ratio than larger cells. The finger-like projection
shape provides more surface area over the small intestines from which they absorb nutrients and contains blood vessels so nutrients passing through them can enter the bloodstream readily.
b. They have a greater surface area-to-volume ratio than larger cells. The finger-like projection
shape is present in the middle of microvilli, which have more surface area over the small intestines from which they absorb nutrients and also contains blood vessels so nutrients can enter
the blood easily.
c. They have a greater surface area-to-volume ratio than larger cells. The finger-like projections prevent large particles of food from passing through the digestive system and also contain blood vessels so nutrients passed through them can readily enter the bloodstream.
d. They have a greater surface area-to-volume ratio than larger cells. The finger-like projections aid
in mechanical digestion of food particles and contain blood vessels so nutrients passing through them can enter the bloodstream readily.
