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 <em>Epulopiscium fishelsoni</em> 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.
This process is called Denitrification. The process is undertaken by the denitrifying bacteria, whose action is converting nitrates in the soil to free atmospheric nitrogen and therefore, depleting soil fertility and reducing agricultural productivity. Examples of denitrifying bacteria are thiobacillus denitrificans, micrococcus denitrificans among others.
Cell, and gas are for sure made up of atoms so it’s either heat or a solid
The answer is D has mitochondria and chloroplasts. In the leaf, so must have chloroplast, most eukaryotic cells have mitochondria (powerhouse of the cell)
