Answer: This is because 2 pyruvate molecules were produced in Glycolysis,and each must be metabolize to extract one ATP molecule each contained.
In addition to produced required number of reduced Co-enzymes for Electron Transport Chain (ETC) reactions to take place for ATP production
It must also be twice/glucose molecule to generate required volume of oxygen for decaboxylation,because the oxygen in the reaction came from.from . redox and not from the atmosphere.
Therefore the both the link reaction and the kreb.cycle
must occur twice to produce mandatory 2 ATPs ,and generate the required amount of reduced Co Enzymes NADH and FADH2 for ETC(electron transport Chain ) to occur.
Explanation:
Spread of disease is the answer.
Disease can cause an epidemic which can lead to mass population decline.
cells become specialized in structure and function, and these are organized into tissues and organs. Activities of a cell depend on the genes it expresses and the proteins it produces. Specific activators turn on the collection of genes whose products are needed in the cell. Materials placed into the cell by the mother set up a sequential program of gene regulation that's carried out as cells divide.Explain what occurs in morphogenesis:The physical processes that give an organism its shape. Literally meaning, "creation
Answer:
A genetic map of the 23 human chromosome
Explanation:
Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
