Answer:
Electron transport chain
Explanation:
Cellular respiration is the process whereby glucose is broken down in the cell to yield energy in form of ATP. This process, which is important to the metabolic functioning of every organism, occurs in three major stages namely: glycolysis, kreb's cycle and electron transport chain (ETC).
According to this question, a stage of respiration is described as follows:
- Two pyruvate molecules undergo a chemical reaction, combining with coenzyme A to form two acetyl-CoA molecules.
- Two carbon dioxide molecules and two NADH molecules are formed as a result of this process.
The process depicted above is KREB'S CYCLE of cellular respiration, hence, the stage of respiration that immediately follows the process is called ELECTRON TRANSPORT CHAIN (ETC).
The gas form of water is water vapor.

B
Explanation:
It is not a direct transmitting of heat.
Answer:
b. <em>Homo neanderthalensis</em>
Explanation:
<em>Homo neanderthalensis </em>are extinct species of the Homo genus which lived in Eurasia until 40000 years ago. They initially lived in Europe and then migrated to Central and Southwest Asia. Compared to modern humans, they had shorter legs and bigger bodies.
They have been known to construct huts out of mammoth bones. Archaelogists discovered a Neanderthal hut structure made of mammoth bone which is considered to be 44000 years old. This structure was 26 feet wide and mostly used for domestic purposes. Previously <em>Homo neanderthalensis </em>were considered primitive creatures who lived in natural caves but after this discovery it has been accepted that they were also advanced.
