Answer 1

Answer:

Viruses and prions are considered microbes.

Some microbes are visible to the naked eye.

Explanation:

Microbes are the tiny organisms that can not be seen with unaided eyes. However, this does not hold true for all and some microbes like Epulopiscium fishelsoni can be seen with unaided eyes. Bacteria, viruses, protozoans, and prions are some of the microbes. Viruses are the microbes that have a protein coat around their genetic material. Prions are proteins that can cause infections. Prions do not have any genetic material.

Answer 2

Answer: option A and D.

Some microbes are visible to the naked eye. Virus and prions are considered as microbes.

Explanation:

Microbes or microorganisms are small living creatures that are either microscopic (not visible with the naked eye or seen with microscope) or visible to the naked eye when they form colony that are found everywhere. Most microbes are beneficial to man in that they aid digestion of food and decomposition of organic material which serve as fertility to soil. Examples of microbes are Bacteria, fungi, viruses, prions e.t.c.

Though some microbes are pathogens I.e they cause diseases but many microbes are beneficial.
