It happens from the air we breath. We breath in oxygen with our lungs. Your body filters out the oxygen and carries it to all parts of your body, the waste is carbon dioxide. Plants use CO2 or carbon dioxide to make food. We get clean oxygen from plants. See how trees are useful?
<span>When a cell is "at rest" it is in a state called the resting potential.
In this state, neurons are more negatively charged ions inside the cell than outside the cell.
A resting neuron also known as non-signaling neuron. A neuron is made up cells.There are many types of cells in the body. The approximate value of cells is 37.2 billion in our body.</span>

<span>The two types of cell cycle genes that, if mutated, cause cancer cells to divide uncontrollably are called tumor suppressor genes and proto-oncogenes</span>
enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
