Explain how bacterial cloning can increasing the amount of dna (dna amplification) and when it is implemented in science or in medicine. use a diagram if needed.

The process of gene cloning involve multiple steps. It involves many enzymes, bacterial cell, vector to produced an amplified number of cell and hence product.

The gene of interest is find and then it is carried into the bacterial cell by the help of vector.

The vector is then carried to get incorporated into the bacterial cell. In this way the bacterial cell starts replicating and the and the desired product is produced in high amount.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
