One kind of plant has only blue flowers and white flowers. according to a genetic model, the offsprings of a certain cross have a 75% chance to be blueflowering, and a 25% chance to be white-flowering, independently of one another. two hundred seeds of such a cross are raised, and 142 turn out to be blue-flowering. are the data consistent with the model? answer yes or no, and explain briefly.

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
