In cattle, black coat, B, is dominant to red coat (b). Hornless, H, is dominant to horned (h). A certain bull was mated to four cows. Cow 1, black and hornless, gave birth to a red, hornless calf. Cow 2, red and hornless, gave birth to a black, horned calf. Cow 3, black and horned, gave birth to a red, horned calf. Cow 4, red and horned, gave birth to a black, hornless calf. What is the genotype of the bull? What are the possible genotypes of each of the cows and their calves? Please help, its worth a lot, and the last person that "helped" me just made up an answer :( I have no idea how to do it. I will mark brainliest.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
