Q:

The main result of aerobic respiration is the

A) production of lactic acid as an end product B) production of ATP from the breakdown of glucose
C) conversion of radiant energy into chemical energy D) storage of energy in a polysaccharide
 
Answer & Explanation Answer: B) production of ATP from the breakdown of glucose

Explanation:

The three steps within the aerobic respiration process are glycolysis, the citric acid cycle, and oxidative phosphorylation.

Photosynthesis builds glucose, and what was built in photosynthesis is broken down during aerobic respiration.

 

Hence, production of ATP from the breakdown of glucose is the main result of aerobic respiration.

Q:

Two metallic wires made from copper have same length but the radius of wire 1 is half of that of wire 2. The resistance of wire 1 is R. If both the wires are joined together in series, the total resistance becomes

 

A) 2R B) R/2
C) 5R/4 D) 3R/4
 
Answer & Explanation Answer: C) 5R/4

Explanation:

So, resistance of Wire 2 is R/4 as radius is half of wire 1, so area would be 4 times of wire 1.

Now for resistance in series. R= R1 + R2.

Therefore, Final R= R + R/4 = 5R/4

Q:

Designing pricing strategies and programs :

How do sellers respond to price changes of their competitors?

Answer

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.
