Which of the following is a function of the placenta?: mixing the blood of the mother and the fetus protecting the fetus from drugs, such as alcohol, in the mother's body providing nutrients to the fetus cushioning and protecting the fetus

Your answer should be: Providing nutrients to the fetus, cushioning and protecting the fetus. Mixing the blood of the Mother and Fetus would not protect him/her from drugs because if it is in the Mother's system then it will affect the Fetus.
