Questions

In the light of competition, it may be seen that competitors may initiate price changes. If the cutting off on prices does not affect the company, then the current pricing strategy itself can be continued to maintain the profitability of the company. However if the price change on one firm is affecting the other, then it can:

a.reduce the product price at par with competitors’ price or below competitors’ price

or

b. Provide added advantage to the existing product like better quality, or ‘a buy one get one free’ offer.

or

c.Provide better quality of the product at a higher price thereby not being at par with the competitors.

A redox reaction is a type of reaction which involves transfer of electrons among two species. This reaction is also called oxidation-reduction reaction.

In oxidation process, there is an increase in oxidation state of an atom, ion or molecule by losing the electrons.

In reduction process, there is a decrease in oxidation state of an atom, ion or molecule by accepting the electrons.

1)

In this reaction, Ba undergoes oxidation and Cl undergoes reduction.
This reaction is redox reaction.
In this reaction, oxidation number of Ba increases from 0 to +2 . So, Ba undergoes oxidation. The oxidation number of Cl decreases from 0 to -1. So, Cl undergoes reduction.

2) 

From this above reaction, it is clear that Aluminum undergoes oxidation and silver undergoes reduction.
Due to this, this reaction is redox reaction.

In this reaction, oxidation number of Aluminum increases from 0 to +1. So, aluminum undergoes oxidation. The oxidation number of silver decreases from +1 to 0. So, silver undergoes reduction.

3)

In this reaction, Mg undergoes oxidation and Br undergoes reduction.
This reaction is redox reaction.
The reactions 1, 3 and 4 are redox reactions.
In this reaction, oxidation number of Mg increases from 0 to +2 . So, Mg undergoes oxidation. The oxidation number of Br decreases from 0 to -1 . So, Br undergoes reduction.

Hence all the above reactions are redox reactions.

The central nervous system CNS is responsible for integrating sensory information and responding accordingly.

It consists of two main components::

 1. The brain

 2. The spinal cord

The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. The brain can be divided into four main lobes: temporal, parietal, occipital and frontal.

The spinal cord serves as a conduit for signals between the brain and the rest of the body.

The best example for somatic mutation would be cancer, familial cancer (which transmits through gametes to the next generation) are not so common while sporadic cancer is seen the most where body cells of a particular area goes through mutations for a number of years and becomes cancerous, but it is not transmitted to next generation.

Here, “to reach in time” should be used. Idiom in times mean, not late. with enough time, to be able to do something

Activation energy is a minimum amount of energy that required for the chemical reaction to happen or to take place.

The potable water is the water, which is tested and safe for drinking purpose and cooking preparations. The water is tested and purified in industries. So, the potable water is costly.

Hence, Access to potable water is most heavily limited by money.
