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 "

Answer:
- Continuous cultivation of crops in soil leads to the depletion of certain nutrients.
- If these nutrients are not replenished, soil becomes sterile and unfit for cultivation.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. ... Cells have many parts, each with a different function.
