In a cladogram, what occurs at a node?

Biology
1 answer:
avanturin [10]3 years ago

<span>A terminal node is the hypothetical last common ancestral interbreeding population of the taxon labeled at a tip of the cladogram. An internal node is the hypothetical last common ancestral population that speciated (i.e., split) to give rise to two or more daughter taxa, which are thus sister taxon to each other</span>

Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydr
Ksivusya [100]

Answer:

The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.

Explanation:

In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).

In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.

The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.

VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.

In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.

A person has polydactyly (extra fingers or toes). Polydactyly is caused by a dominant allele.
Helen [10]

Answer:

1 I think, read the explanation.

Explanation:

Offspring need to carry just one dominant allele from their parents to inherit the polydactyl condition. The probability of the offspring having polydactyly is 50% (2 of the 4) and 50% not having it (normal). This can be expressed as a ratio, 2:2 which can be simplified to 1:1. - found on the internet

Which of the following describes the structure and function of the cell membrane?
mamaluj [8]

Answer:

A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell
