Answer:

Option C,  Earth's temperature was too high for solid rocks to form.

Explanation:

During the Hadeon age ( some 4.6 billion years ago), the earth was at its initial stage of formation. By that time the temperature of earth was extremely high and extraterrestrial bombardments from  other planets or celestial structures further raised the earth’s temperature. Due to such extremities and high temperature the rocks at the surface of earth could not solidify and hence no traces of rocks can be found from the Hadeon era.

Dimas [21]

Answer: B.) More research is needed to reach a conclusion, including related variables

Explanation:

As it is evident that oxygen is necessary element for living beings. It is required for the process of respiration, in which the food particles are broken down in the presence of oxygen into simpler substances.

Applying this knowledge to the given study suggests that all organisms require oxygen which can be less or more depending upon their habitat either in the shallow waters or in the depths. This conclusion is invalid and requires more explanatory approach which can be achieved by more research so as to derive a valid conclusion in which the two variables oxygen and relative habitats can be compared.

How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?
Len [333]

Answer:

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.
