Answer:
DNA: Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids.
RNA: You can think of the sequences of bases in the coding strand of DNA or in messenger RNA as coded instructions for building protein chains out of amino acids. There are 20 amino acids used in making proteins, but only four different bases to be used to code for them. Obviously one base can't code for one amino acid.
Answer:
Optimum pH= 6
Optimum pH for the given enzyme would be the average of pKa values of two amino acids (2.9 + 9.1 /2= 6)
Explanation:
The pKa represents the association constant of amino acids. It is calculated by taking the negative log value of the ratio of a dissociated acid and the conjugated base which in turn regulates the isoelectric point (pI) of the protein.
The amino acids present in the active site of the enzyme regulate the interaction of enzyme and substrate. The given enzyme contains two ionizable amino acids with pKa values of 2.9 and 9.1 respectively. Therefore, the optimum pH of the given enzyme would be 2.9 + 9.1 / 2 = 12/2 = 6.
At pH 6, both the ionizable amino acids would serve as a good buffer with their active proton donor and proton acceptor species.
Spring-loaded devices not recommended for glucose monitoring when collecting a sample into a microcollection container because "These devices produce only two or three drops of blood. "
<h3>What is glucose?</h3>
The main source of energy for the body's cells is glucose, which is the most prevalent kind of sugar in the blood. Glucose can be produced by the body from other substances or it can be obtained through food. The circulation carries glucose to the cells. Insulin is one hormone that regulates blood glucose levels.
<h3>What does it mean when your glucose are high?</h3>
Because the body doesn't produce enough insulin when there is too much sugar in the blood, hyperglycemia (high blood glucose) results. Vomiting, an insatiable appetite, intense thirst, a rapid heartbeat, eyesight issues, and other symptoms are all signs of hyperglycemia, a sign of diabetes. Serious health issues may result from untreated hyperglycemia.

Answer:
Animal behavior includes all the ways animals interact with other organisms and the physical environment. ... Behavior is shaped by natural selection. Many behaviors directly increase an organism's fitness, that is, they help it survive and reproduce.
