Humans also carry out lactic acid fermentation. while many cells in the human body can produce atp in this way, muscle cells are the best adapted to perform fermentation. think about how oxygen supply in the body changes with vigorous exercise. why does it make sense that muscle cells would be the best adapted to carry out fermentation?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
