A yellow haired rat is mated with a black haired rat. Over time, the rats produce 45 black offspring and 52 yellow. From the results, determine the probable genotype of the parents and offspring. How could you determine what the dominant allele is?

answer; /// i believe the correct answer is (reactants);

a chair, a bed, and a toothbrush

explanation:

the endomembrane system i think

plants absorb water from the soil by osmosis. root hair cells are adapted for this by having a large surface area to speed up osmosis. the absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: it transports dissolved minerals around the plant.
