Genetical experiments suggest that traits acquired during a person's lifetime are not inherited as proposed by Lamarck's theory that traits acquired or changed over an individual's lifetime could be passed on to its offspring. Through experiments, scientists through many observations and real examples that changes that often occur in an animal's life are not passed down to it's offspring.
Answer:
The conversion is needed to regenerate the molecules needed for glycolysis
Explanation:
Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.
The two kinds of basic cell division include mitosis and meiosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. So this means that when the cell division is complete, the number and even the sequence of chromosomes is exactly same as the original parent cell.
And in meiosis, also called reduction division, is where the parent cell divides and produces 4 genetically different daughter cells, which has only half of the number of chromosomes than that of the original parent cell. This process has to go through 2 times of divisions.
Mitosis is usually seen in most somatic cells, it is very important to activities such as growth, repair etc. Meanwhile, meiosis is seen in gametes, and its important for sexual reproduction.
