Answer:Diploid
Explanation:Human has a complex multicellular body. Based on their functions, it has two types of cells: somatic cells and germ cells or sex cells. The somatic cells are involved in various body functions except for reproduction and are diploid with 2n=46 chromosomes. The germ cells are involved in gamete formation and reproduction. These cells are haploid with n = 23 chromosomes.
Answer:
B. In the small intestine, carboxypeptidase attacks peptide bonds.
E. Pepsin causes the hydrolysis of some of the peptide bonds in proteins.
Explanation:
The digestion of protiens doesn't occur in mouth, it occurs at only 2 locations in GIT :
- In the stomach
- In the small intestine
Digestion of protiens start in stomach causing the stimulation of gatrin hormoone which stimulates the release of gastric juice containing HCl , Pepsinogen , Rennin (in infants). The pepsinogen is activated to pepsin by HCL and pepsin itslef, and cause hydrolysis of the peptide bonds in the protiens.
The remainder of protien digestion occurs in small intestine as a result of the action of enzymes including trypsin and peptidases. Carboxypeptidases attack the peptide bonds and result in cleavage.

Endothermic change
Explanation:
Enthalpy changes are heat changes accompanying physical and chemical changes. There are two types of enthalpy changes: Endothermic change and exothermic change.
In an endothermic change, heat is absorbed from the surround and hence the surrounding becomes colder at the end of the change.
A change that leaves the reaction colder is an endothermic change.
