Answer:
Sound is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles. These particles bump into the particles close to them, which makes them vibrate too, causing them to bump into more air particles. This movement, called sound waves, keeps going until they run out of energy.

Pellet can be described as a compressed mass of a substance, which is usually have round shape and small size.

The parts that are not digestible form a pellet.
It should be noted that the pellet is stored for several hours, after which it is regurgitated.
Most life cycles of large stars end in them becoming either a neutron star or a black hole.
2 pyruvate molecules
Explanation: Pyruvate is a product product of glycolysis.
Input: 2 NAD+ output: 2 NADPH
Input: glucose: output: 2 pyruvates
Input: 2 ATP (note: glycolysis has an energy investment phase and an energy payoff phase. it uses 2 ATP and produces 4 ATP. The net ATP is 2, making it an output aka product.)
