A developing embryo derives its nutrition from the mother
Answer Details
The correct answer is: "through the blood vessels located in the placenta". During pregnancy, the placenta is the organ that connects the developing embryo to the mother's uterus, and it acts as a source of nutrients, oxygen, and hormones for the developing fetus. The placenta develops blood vessels that allow the transfer of nutrients and oxygen from the mother's bloodstream to the developing embryo, and the removal of waste products from the embryo's bloodstream. Therefore, the developing embryo derives its nutrition from the mother through the blood vessels located in the placenta.
