The small intestine performs a key role in the digestion of undigested food which comes through the stomach. It also absorbs all the essential minerals and nutrients from the food and is used by the body.

Villi or microvilli is the structure that increases the surface area of the small intestine for food absorption and adding digestive secretions.

Therefore, the name of the structure that increases the surface area of the small intestine in humans is Villi.

Emulsion of fatty acids is necessary to _____.
kap26 [50]

Answer:

c. increase the surface area available for hydrolysis by lipase

Explanation:

Emulsification of fats(fatty acid) is a chemical reaction where large molecules(globules) of fats are broken down into a smaller molecules (droplets) by the action of an emulsifier.

In the human body, emulsification takes places in the duodenum during the process of digestion of fats. When large fat molecules have been broken down into smaller fat molecules by action of an emulsifier called bile salts from the gall bladder, a larger surface area is created which makes it possible for the enzyme lipase from the pancreas to react with or act on fat molecules through the process of hydrolysis thereby converting the fats to fatty acids and glycerol for use by the body.

Would mouth to mouth resuscitation between two fish work?
Nady [450]

I don't think it will work.

Fish breathe with gill not lungs. Unlike lungs, gill works one way. You breathe out air out of you mouth but fish dump the water from their gill so they shouldn't be able to push water out of their mouth.

Even if the could fish push the water through their mouth, the gas exchange didn't happen because the water didn't move through the gill. The fish that giving water cannot breathe while giving resuscitation.

The life cycle of plants includes a haploid generation and a diploid generation. Both the structures are multicellular.

The diploid structure of a plant is known as sporophyte. This structure produces spores via meiotic division.

Whereas, the haploid structure of the plant, known as the gametophyte, is formed from spore and produces haploid gametes.
