Question

What should be changed to make the following sentence true? The zygote is a structure connected to the uterus that provides nourishment and oxygen from the mother to the developing embryo via the umbilical cord.

Answer 1

zygote should be changed to placenta

Step-by-step explanation:

A zygote is formed when the sperm has already fertilized the egg cell. It will then be implanted on the uterine wall of the mother. The zygote will then develop into the embryo, normally during 3-8 weeks. This embryo will then be surrounded by the placenta which developed from blood vessels. The placenta that is connected to the uterus allows for oxygen and other nutrients to move from the mother to the developing embryo through the umbilical cord.
