The answer would be (b) evolutionary species concept.
Answer:
b. Sufficient concentration and correct orientation of particles
Explanation:
Collision theory states that when two suitable particles states that when suitable particles of the reactant collide with other and causes any noticeable chemical change, these successful changes are called collisions.
<em>Two factors that responsible for collision are reactant concentration and correct orientation of particles. </em>
<u>Reactant concentration:</u><u> </u>higher concentration of reaction will increase the rate of reaction as, it will provide more reactant to collide in a specific time period.
<u>Orientation of particles:</u> the correct orientation of particles facilitate the forming and breaking of bonds and arrange the atoms to form product molecules.
Hence, the correct option is "Sufficient concentration and correct orientation of particles "
Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Answer:
Photosynthesis is the process of making food by green plants in the presence of sunlight.
Explanation:
During Day, sunlight enters through stomata and carbon dioxide from air and water forms glucose and oxygen. This process is photosynthesis.
