...were due to single genes and followed simple inheritance patterns (dominant/recessive).
Explanation:
The traits Mendel studied were easy to track because the two possible outcomes were distinct and the trait itself was visible and trackable. The fact that they followed simple inheritance patterns helped him when he was determining his ratios for different crosses because complex inheritance would've muddled his data.
because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time.Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly
