Answer:
Epinephrine, also known as Adrenaline
Explanation:
Adrenaline impacts short-term mood and can take seconds to flood your system.
*it may also be cortisol, I'm not sure if there's more context. Cortisol takes longer to work and can have long-term effects.
Glycine is the principle amino acid and it helps in the production of all types of amino acid.
Glycine is the simplest form of amino acid. all the amino acid is a derivative or a side chain addition of the amino acid of glycine.
Glycine is a highly conserved amino acid in the evolution of proteins as it is the smallest amino acid with H as a side chain. Because of the smallest side chain, it makes peptide to have tight turns. Because of Glycine smallest size proteins can approach one another very closely.
Various studies have been conducted to prove that glycine is a conserved amino acid. An experiment is conducted where glycine in a protein is being replaced by other amino acids say alanine, serine. This mutated protein where either serine or alanine took the position of Glycine, become unstable as confirmation was not stable in any variant. Conserved amino acids or sequences are those which affect the confirmation of the protein.
Glycine is only optically inactive amino acid and being the compact amino acid, it form stable alpha helices whereas complex amino acid like proline destabilize the helix.
Hence it is a highly conserved amino acid. Proteins are the addition of different types of amino acid. The amino acid at the edition product of different side chain which are present in glycine. all amino acids are modification of glycine and can be prepared from glycine.

Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
