Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.
Explanation:
Answer:
true
Explanation:
glucose is the primary nutrient for all living things
Answer:
Only one of the three statement is true; and that is,
(ii.) Different metabolic end products result from the two types of fermentation
Explanation:
Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.
Fermentation is carried out by many organisms including man.
In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.
In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.
From the options provided in the questions, the correct option is:
Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.
A germ-line mutation in one of the genes implicated in the cancer occurred in an ancestor.
