Since the dimple trait is simple dominance, it therefore can be inherited in both the homozygous (DD) and heterozygous form (Dd). For non dimples we have (dd).
Thus, for a dimpled man whose mother has no dimples, it can be concluded that he is an heterozygote. (For him to be dimpled with a non dimpled mom, his dad has to be either an homozygous/heterozygous dimpled man. Since his mom is non dimpled (dd), therefore he can only be an heterozygous)
Therefore, a cross between a dimpled man (Dd) and a non dimpled woman will give.
Answer: "To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells."
