One of the events that could give credence to the panspermia hypothesis would be the presence of carbon-based molecules on meteors that strike the earth's surface.
<h3>Evidence of extraterrestrial lives</h3>
All biomolecules of life are carbon-based. Examples of these molecules include carbohydrates, proteins, ribonucleic acids, etc.
In order for life to exist in a place, carbon must be abundant.
Thus, the presence of carbon-based molecules on meteors from another planet that hit the surface of the earth may be evidence that life exists on another planet.
This can be used as evidence that life on earth came from extraterrestrial sources.

The correct answer is A.chemical energy in the bonds of food molecules.
The cells require a constant supply of energy to generate and maintain their functions. Sugars are most commonly used as fuel molecules (especially glucose). Food Molecules Are broken down in three stages: the first step is digestion (intestine), second is glycolysis (cytosol) and the third is the citric acid cycle together with oxidative phosphorylation (mitochondria). During the process of oxidative phosphorylation, ATP is produced.
