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.
Answer:Four spheres of earth are:1)Lithosphere(land) 2)Hydrosphere(water) 3)Biosphere(living things) 4)Atmosphere(air).
Energy and matter flow through Earth's four spheres.Energy flows through the atmosphere and hydrosphere mostly by convection.The continuous cycling of matter and energy through earth's system makes life on earth possible .Others are driven by energy from the sun.

Answer:
The bacteria were growing through fermentation process.
Explanation:
Cyanide have the ability to prevent the growth of microbes, and that is why it usually added to paints that want to be applied to places where the growth of microbes will be harmful to people.
The ships' hull where ballast water is been stored needed to be painted with cyanide to prevent the growth of microbes.
It should be noted that, anaerobic microbes have the ability to reduce cyanide compound through a process known as submerged fermentation.
In the case of ships' hull, the bacteria growing on the hull were anaerobic, which means, they carried out their activities in the absence of oxygen.
