A submersible technology designed to operate the submarines underwater.
Explanation:
We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.
D. Endoskeletons are inside, like our bones, and get bigger as we grow. Exoskeletons don't, which is why they have to shed and regrow a new one when they grow.
I think this one fits: <span>C. It has a small temperature range during the summer. As there's much greater temperature range in summer than in alpine biome.</span>
