in the process of meiosis the new cells have half the dna of the original cell why is this important to life HELP PLEASE THIS IS DUE IN 1 MINUTE

the meiosis is a process of cell division through which haploid cells are formed, it generally occurs during formation of gametes ( sex cells ) it is very important, because each parent contribute half number of chromosomes to the offspring, and that's the reason we have same number of chromosomes as our parents

( hence maintains the numbers of chromosomes in offspring )

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. During meiosis one cell divides twice to form four daughter cells.

This is because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes to make a human child.

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.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
