In mammals, the placenta is essential to the embryo for  

• nutrition, reproduction, and growth 
• nutrition, respiration and excretion 
• locomotion,respiration, and excretion 
• nutrition, reproduction, and excretion

The diagram below represents one stage during the human reproductive process. A function of structure A is to    

• remove nutrients from the fetus 
• provide the fetus with metabolic wastes
• remove all toxins from the blood of the mother
• provide for the exchange of oxygen and carbon dioxide

Base your answer on the diagram below and on your knowledge of biology. The arrows in the diagram represent processes.  Process B is known as    

• meiosis
• oogenesis
• differentiation
