Answer:
b. Alternatives to nonrenewable energy sources can be as effective.
Explanation:
There are, 7 Carbon atoms, 10 Oxygen atoms, 12 Hydrogen atoms in the reactants and 1 Carbon atom, 3 Oxygen atoms, 2 Hydrogen atoms in the products.
<h3>How to count the number of atoms in reactants and products?</h3>
- Write down the chemical formula that is:
+
→
+
+ 
- List all the atoms present in the equation:
C
H
O
- Count the number of atoms of the element of each molecule in the reactant.
C=6
O=8
H=12
- Count the number of atoms of the element of each molecule in the Product.
C=1
O=8
H=2
Hence there are, 6 Carbon atoms, 8 Oxygen atoms, 12 Hydrogen atoms in the reactants and 1 Carbon atom, 3 Oxygen atoms, 2 Hydrogen atoms in the products.

<span>The repolarization of cardiac muscle is due to closure of calcium (Ca) channels and potassium (K) exiting the cell when additional voltage gated K channels open.
Due to these changes within the heart, repolarization has to happen. This process refers to returning the cardiac muscle to its resting state, and the opposite process is depolarization.

Answer:
nuclear energy
Explanation:
An atom has a nucleus (or core) containing protons and neutrons, which is surrounded by electrons. Protons carry a positive electrical charge, and electrons carry a negative electrical charge. Neutrons do not have an electrical charge.
