Answer:
Chitin
Explanation:
Chitin is the polysaccharide that makes up the outer exoskeleton of many insects. It is a fibrous polymer, that is made up of chains of modified glucose molecules. It is comparable in structure to cellulose, which makes up the plant cell wall. In function, it is more similar to keratin or collagen, although these are proteins.
Chitin is exclusively found in the arthropods, mollusks and fungi. It plays an important protective and structural role, giving organisms their tough outer exoskeleton or strong cell wall in the case of fungi.
Glucagon levels increase, Blood glucose legrls begin to increase.
Glucagon converts Glycogen stored in the liver back to Glucose to be used by the body as energy.
Answer: B
Explanation: Multiple different combinations of bases (A, G, C, T) can code for the same amino acid. This means that there are more possible combinations of the bases than there are amino acids. There are 20 amino acids and the four bases can have up to 64 different codon combinations.
