Question

Bacteria and viruses are favourite experimental organisms for studying the genetical phenomenon of living organisms, which of the following is an appropriate reason for such a choice:

• A. They have a very simple method of sexual recombination.
• B. They are tough, they do not die easily.
• C. They have a very high rate of reproduction.
• D. They have a very long life-span which makes long-term studies possible.

Answer 1

The correct option is C

They have a very high rate of reproduction.

The correct option is C.

Explanation of the correct option:

1. Bacteria are the most abundant, unicellular, prokaryotic organisms. They are ubiquitous and found everywhere.
2. Viruses are the minute particles much smaller than bacteria which can be observed only with the help of electron microscopes. Viruses live and grow only inside the living cells.
3. The reproduction rate of both bacteria and viruses is very high, in a single reproductive period they can produce millions of daughter cells.
4. Therefore, these are used as experimental organisms. Higher numbers of organisms are available for carrying out an experiment.

Final Answer:

Bacteria and viruses are favourite experimental organisms for studying the genetical phenomenon of living organisms because, they have a very high rate of reproduction.
