Answer:
Conserved
Explanation:
In balancing nuclear reaction equations, there is conservation of mass numbers and atomic numbers, i.e the sum of the mass number on the product side must be equal to the sum of mass numbers on the reactant side.
Also, the sum of the atomic numbers on the product side must be equal to the sum of the atomic numbers on the reactant side.
Note: A nuclear reaction is a process in which a nucleus reacts with an elementary particle.
Answer:
The mouth begins the process of digestion by mechanically breaking food into smaller pieces.
Explanation:
Digestion is a crucial process that involves the break down of complex food molecules into simpler ones that are assimilable by the body. The process of digestion in humans, for example, is said to begin in the MOUTH where the food enters through.
The mouth via the use of teeth helps the initially break down the food particles using mechanical/physical method. This further helps the break down of the food into tiny particles before they are acted on enzymatically.
The answer is (4) the particles have more energy and collide more frequently.
