Reactions which emits energy in the form of light or heat are called exothermic reactions.
reactant(s) --------------> product(s) + heat
Reactant which absorbs energy in the form of heat or light are called endothermic reactions.
reactant(s) + heat -----------> product(s)
Hope this helps!

Explanation:
Answer:DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Explanation:
Answer: A reaction which occurs when equivalent quantities of H" (or 
) and OH" are mixed is a neutralization reaction.
Explanation:
When acid and base chemically combine together to form sat and water then it is know as neutralization reaction.
An acidic substance gives hydrogen ions 
on dissociation and a basic substance gives hydroxide ions 
on dissociation.
For example, 
is a neutralization reaction where an acid and base are mixed together to form water.
No salt is formed as because here the reactants are not present as compounds.
In a hydrolysis reaction, water molecule(s) is added to the reactant molecules.
For example, 
Oxidation is the process of addition of oxygen to a molecule and removal of hydrogen.
Reduction is the process of addition of hydrogen in a compound and the removal of oxygen atom.
Therefore, we can conclude that reaction which occurs when equivalent quantities of H" (or ) and OH" are mixed is a neutralization reaction.
