Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon.

Answer:
See the answer below
Explanation:
First, let us look at the complete equation of respiration:
The respective number of each atom in the reactants and the products can be filled in the table thus:
Types of atom Number of atom in reactants Number of atom in products
Carbon 6 6
Hydrogen 12 12
Oxygen 18 18
<em>The total number of each atom in the reactants is equal to the total number in the products. Hence, the calculation confirms the law of conservation of matter that says that matters can neither be created nor destroyed, but can be converted from one form to another in a course of a reaction. </em>
