Data collected by the drilling ship Glomar Challenger confirmed that C. NONE OF THE OCEAN FLOOR IS MORE THAN 180 MILLION YEARS OLD.
Glomar Challenger began drilling on both sides of the mid-ocean ridges to gather data. The data confirmed what the sea-floor spreading hypothesis predicted. The ocean floor is youngest along the central valley of the mid-ocean ridge while the ocean floor in subduction zones or near the edges of the continents is oldest. The data has confirmed that none of the ocean floor is more than 180 million years old because the older oceanic rock will undergo subduction and go back to the earht's mantle.
Answer: Implantation
Explanation:
The uterus is the main site for the implantation of the embryo. It is the place where the embryo spends 9 months in the mother.
When the male and female gamete combine they form a zygote. It gets implanted in the uterus and then there is cell division and the development of embryo takes place there only.
Any abnormalities in this region will interfere in the process of implantation.
I would guess C, hope that helps!
