Answer:
<em>Digested food is a source of potential energy</em>
Explanation:
When we digest food, the molecules of the food are broken down into smaller compounds. Chemical energy is released due to this process. Chemical energy can be used to form glucose and fat. These molecules store energy in them. When energy is required by the body, the glucose molecules can be converted into ATP and hence give energy. This energy can be used for various purposes such as it can be converted into mechanical energy for muscle movements.
<span>The answer to the question stated above is letter A. Cell Structure.
In the new 6-kingdom system of classification, like the old 5-kingdom system, organisms are basically grouped by</span><span> cell structure.
The new 6-kingdom system of classification includes the following:
</span>Animalia<span>, </span>Plantae<span>, </span>Fungi<span>, </span>Protista<span>, </span>Archaea/Archaeabacteria<span>, and </span>Bacteria/Eubacteria.
The sperm are changing chemical energy into kinetic energy.
Chemical energy is defined as the chemical substance’s potential to undergo a transformation through a chemical reaction. So, this type of energy can be transformed to other forms of energy by a chemical reaction.
Kinetic energy, on the other hand, is the energy that an object (structure) possesses due to its motion.
So, in the example above, chemical energy of the glucose is used (by breaking the bonds of this molecule through the chemical reaction) for the formation of sperm’s kinetic energy (necessary for movement).
