The correct option is C.
In chemistry, a radical is defined as an atom, ion or molecule that possess an unpaired valence electron. Generally, radicals are highly reactive chemically. Examples of radicals are hydroxyl, hypochlorite, nitrate, carbonate, oxalate, permanganate, etc. Free radicals combine with one another or with single atoms to produce neutral substances. In the question given above, the two compounds given in option C have the same type of radical, which is hydroxyl radical.
One way is to see if it responds to stimulants or if it reproduces
That prokaryote is <span>Psychrophile, a coccus and a decomposer.
1)The prokaryote is</span> shaped like a ball or generally has a round shape so it's called a coccus (Cocci in plural). This is one out of three terms, that are used to name bacteria. The other ones are bacillus and spiral. For example, Staphylococcus aureus is a bacteria that has a round shape but it's formed by more that one ball, that together look like a bunch of grapes.
2) This organism lives deep under the water, so it's named as a psychrophile or cryophile. This means they can live and reproduction at extremely low temperatures(-20ºC), and some places with those temperatures are the polar regions and the deep sea.
3) This prokaryote consumes dead organisms so it's classified as a decomposer.
Decomposers are organisms that can break down dead or decaying organisms. The process is an essential part of the nutrient cycle and is important for recycling the organic matter that occupies space in the biosphere.
