It allows different kinds of organisms to be easily identified based on their characteristics
Explanation:
Classification is defined as the grouping of organisms based on their similarities and dissimilarities. The main aim of classification is to simplify the study of vast range of animals that exist in nature.
The scientists use a standardized method in which they follow a set of rules while studying and assigning a taxonomic rank to a newly studied organism.
The taxonomic hierarchy includes the following taxon-Kingdom, phylum,class, order, family, genus, species.
Beginning from Kingdom the percentage of similarities among the members keep on increasing while we move towards species.
A taxonomical rank is assigned to an organism by studying the similarities of that organism with already existing members of that taxonomic group.
Since, few characters are already studied well while classifying the earlier members the study and classification of new organism becomes much simplified and easier.

Answer:
Option A
Explanation:
Renewable resources of energy are clean source of energy. They are sustainable as they are readily available, can be used again and again and do not produce any pollution neither during production stage nor during usage stage by an individual.
There are very nations in the world which are oil rich and country itself has no oil reserve. In such scenarios, the dependency of nation on other countries increases. But in lieu to in-house renewable energy resources, country will not import oil from other nations
Hence, option A is correct.
<u>Answer</u>:
1. The purpose of the uninoculated control tubes used in the oxidation fermentation test is to serve as basis of the medium for the color comparison and that it is sterile.
2. It is necessary to use two controls in order to illustrate the no color change (green color) under both aerobic and anaerobic conditions.
3. The purpose of the experiment is to determine if the organisms utilize the carbohydrate and thus is fermentative. This will result in a color change from green to yellow.
Thus, the medium in one tube is sealed with a layer of paraffin to prevent diffusion of oxygen. This tube will show that the medium is unaffected by the lack of oxygen.
The second tube will allow the diffusion of oxygen. This tube will show that the medium does not change color naturally in the presence of oxygen. Thus, the color changes will be caused only by the fermentation process of the organisms.
