If 50 dd/dd pairs of parrots mate, and each pair has 2 offspring, how many of the 100 offspring would you expect to be dd? a. 0 b. 100 c. 75 d. 50

D. 50

Explanation:

When a Homozygous Dominant and Homozygous Recessive breed, the chance for Heterozygous offspring are 100%. Then when Heterozygous breed, there is a 1:2:1 ratio, and there are 50% Heterozygous offspring. 50% of 100 is 50.

-- Brainliest answer is much appreciated! :)

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.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
