Answer:
Due to the absence of proteolytic enzymes.
Explanation:
The study diagnosis that small intestine digested protein slowly due to the absence or decrease quantity of proteolytic enzymes in the small intestine. Proteolytic enzymes are responsible to speed up the digestion process and after digestion amino acid is produced which is directly injected into the blood that is used by the body for the formation of muscles.
The longest phase of mitosis is prophase. Because the nuclear membrane disappears, Nucleolus disintegrates, and the DNA condensed to form chromosomes (each chromosome is composed of sister chromatids attached around centromere.)
A through C actually tend to increase reactions. Catalysts, increased surface area and increased concentration all tend to do that. But decreased temperature means decreased energy and speed of the molecules/atoms, thus slowing the reaction.
