Answer:
C. substances that are used up in a reaction
Explanation:
Substances are combined in a chemical reaction to give rise to other substances. The substances that come together are called REACTANTS while the substances that are produced are called PRODUCTS.
Reactants are used up in the reaction to give rise to new products at the end of the reaction. For example, in the reaction as follows:
6CO2 + 6H2O --> C6H12O6 + 6O2
CO2 (carbon dioxide) and water (H2O) are the REACTANTS of the reaction, which are used up to form glucose and oxygen (products)
The statements describe a spring at its equilibrium position is the elastic potential energy is zero, the displacement of the spring is at a maximum and the net force acting on the spring is zero.
<h3>What is the equilibrium position?</h3>
A body is in equilibrium when the sum of all forces acting on it equals zero. According to Newton's First Law, when resulting from the laws that act on a body that remains in a state of restriction or in motion in its motion, it remains uniformly null.
In this case the only statements that match the definition of equilibrium position are:
- The elastic potential energy is zero.
- The displacement of the spring is at a maximum.
- The net force acting on the spring is zero.

Answer:
They are very similar because they both are very important for the sustenance of the cell. Both also help to provide energy for the cell, Chloroplasts can make its own food through photosynthesis and the mitochondria helps to break down the energy.

Answer:
837.2J
Explanation:
m=4g,c=4.186 J/g/C, change in temperature=75-25=50 degree Celsius Q=?
using the formula
Q=mxcx change in theta
Q=4x4.186x50
Q=837.2J
