Suppose a dominant allele (n) codes for a big nose and a recessive allele (n) codes for a small nose. imagine that an organism receives a dominant allele from its mom and a dominant allele from its dad. what can be determined about its genotype and phenotype? a. the organism has a small nose, because it's homozygous. b. the organism has a small nose, because it's heterozygous. c. the organism has a large nose, because it's homozygous. d. the organism has a large nose, because it's heterozygous.

C, large nose cuz its a homozygous

air, water, heat and noise pollution can all be caused by producing and using technology. consuming resources - non-renewable resources, including precious metals like gold, are used to make technology

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.
