HELP ME I BEEN DOING THIS FOR AN HOUR I CANT DO ITTT ! biology 9grade

tay sachs is autosomal recessive so you need 2 tt for someone to have it

One of each parents is a carrier Tt and the dark ones are tt and then the center 2 parents are both Tt and the circle in the bottom left would be TT

square on the r in the middle row can be anything same as the white square progeny of the same

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.
