Answer:

See the answer below

Explanation:

The phenomenon is best explained by the fact that the <u>genetic codes are degenerates</u>. In other words, more than one codon can specify for the same amino acid being carried by the tRNA.

<em>The base-pairing rule between the third nucleotide of a codon and that of the anticodon on the tRNAs loosens off. For example, GUU, GUC, and GUA all specify for the amino acid valine while GCU, GCC, and GCA all specify for alanine. </em>

Liula [17]

Answer:

When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.

Irina-Kira [14]

Alcoholic fermentation includes: <u>All answers are correct</u>

a. is carried out by yeasts.

b. produces far less ATP than aerobic respiration.

d. produces ethanol.

e. produces carbon dioxide.

Fermentation- Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals.

Aerobic respiration- It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.
