Answer:
1. Exothermic reaction
2. Is being released
3. The energy comes from the change in energy between reactants and products
Explanation:
The reaction is producing energy. A reaction that produce energy is called a <em>Exothermic reaction.</em>
<em />
As the energy is produced, the energy is being <em>released.</em>
<em />
As you can see in the image, the energy of the reactants is higher than the energy of the products. This change of energy in the chemicals produce the production of energy as heat.
Answer:
They are able to perform all necessary functions within one cell.
Explanation:
Exothermic reaction = the term exothermic process describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity,
Endothermic reaction = An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Mainly around the equator, since it receives the most direct sunlight year round.
