Answer:

Size, Spatial Distribution and age structure or, birth and death rates.

Explanation:

Demography is the study of a population, the total number of people or organisms in a given area. Understanding how population characteristics such as size, spatial distribution, age structure, or birth rates change over time can help scientists and/or governments.

Liono4ka [1.6K]

Answer:

It reflects the common ancestry of humans with hairy vertebrates.

Explanation:

Evolution is the change in the species with the passage of time. Some species might get extinct and some species might develop the advance character during the evolutionary process.

The evolutionary history of the organisms can be classified on the basis of the paleontological or molecular evidence. The two groups of the organisms can share a common ancestor if they have some similar features with each other. In the given question, it can be concluded that hairy vertebrates and human might have the common ancestor.

Thus, the correct answer is option (a).

What stage is the glucose molecule formed
anyanavicka [17]

Answer:

  1. GLYCOLYSIS :- Glycolysis is the metabolic pathway that converts glucose C₆H₁₂O₆, into pyruvic acid, CH₃COCOOH. The free energy released in this process is used to form the high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide
  2. PRODUCTS :- Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
  3. INPUT:- Glycolysis is the first step in cellular respiration, occurring in all living cells. Overall, the input for glycolysis is one glucose, two ATP and two NAD+ molecules giving rise to two pyruvate molecules, four ATP and two NADH.
  4. BREAKDOWN:- During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate
  5. STAGES:-
  • Reaction 1: glucose phosphorylation to glucose 6-phosphate.
  • Reaction 2: isomerization of glucose 6-phosphate to fructose 6-phosphate
  • Reaction 3: phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate
  • Reaction 4: cleavage of fructose 1,6-bisphosphate into two three-carbon fragments.
