It can be confusing because it isn't specific enough. In astronomy, the big dipper is not a spoon. It is a bear. Scientists know it as Ursa Major rather than a dipper or bear. 
 
        
             
        
        
        
The answer is; C
Plasmids are conferred through horizontal gene transfer in bacteria.  The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.

Answer: B. Take short showers instead of baths.
Explanation:
The water is the most important non-living environmental factor which is the main requirement for survival of every living being. Even though water is a renewable resource which can be replenish by the mode of water cycling in nature but with the increase in the global population the demand of freshwater has increased. Also with the increase in the causes and sources of water pollution the levels of freshwater sources are decreasing. Therefore, the issues of water conservation should be taken into consideration. 
According to the given situation, if an individual needs to conserve water, take short showers instead of baths is the correct option because of the fact that short showers will prevents the wastage of large amount of water which could be wasted while taking baths.
