Answer:

FALSE

Explanation:

The materials like magma when heated at great depth in the mantle due to the heat energy provided by the interior of the earth, it gets warm and less dense. This materials then starts to rise up due to the force generated by the magma in the upward direction. This hot magma then rises up and eventually cools due to the lowering of temperature in the upper portion of the mantle. This materials after being cooled, becomes less dense and sinks.

This process takes place in a form of a convection cell.

Hence, the above statement is false.

Answer:

The correct answer is D. is a facultative anaerobe

Explanation:

A facultative anaerobe is the organisms that can live in the absence of oxygen but prefer to utilize the oxygen when oxygen is present in the environment.  

An anaerobic organism requires more amount of energy sources like carbohydrates because they use the fermentation process to make energy and this process results in the formation of less energy than aerobic respiration.  

All the bacteria of family Enterobacteriaceae that live in the intestine are facultative anaerobes. Therefore facultative anaerobe can thrive in both the presence and absence of oxygen so the correct answer is D. is a facultative anaerobe.
