Answer:
Emulsifier generally reduces the surface tension of the lipid there by helping in the digestion of the lipid molecules.
Explanation:
Bile that is secreted from liver act as emulsifier because the bile helps in the break down of lipid into small molecules to form micelle thereby reducing the surface tension of the lipid molecules.
Due the formation of micelle the broken down lipid molecules binds to the active site of the lipase enzyme and get digested to form fatty acid and glycerol.
Beside digestion Emulsifier Bile also helps in the absoption of lipid from the small intestine.
Dry climates do not have sufficient precipitation during the most of the year.
Desert are located in the arid climate.
The semiarid climate is in a grassland, or steppe, region.
the role of plants in carbon cycle
Explanation:
the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
