Answer:
Hydroxyl
Explanation:
Hydroxyl groups are simple structures consisting of an oxygen atom with two lone pairs bonded to a hydrogen atom.
A hydroxy or hydroxyl group is a functional group with the chemical formula -OH and composed of one oxygen atom covalently bonded to one hydrogen atom.
Using these given definitions, a hydrogen bond is labeled with one linkage, while a covalent bond is with two links to the Carbon Atom.

There's a shrink to the upward thrust of a sand dune. they do no longer stay interior a similar place yet crawl downwind and are replaced by capacity of latest ones. at last, they attain the factor the place they'd be stabilized by capacity of plant existence. Barrier islands are formed a similar way, different than by capacity of water, somewhat than wind.
Fungi are eukaryotic and saprophytic microorganisms that grow on dead and decaying matter. These organisms release digestive enzymes that break down leaves, fruit and other organic material into simple molecules. These can grow on wood, clothes, food, fruits, leather shoes, etc by breaking down complex organic matter into simpler forms with the help of extracellular digestive enzymes such as cellulases, proteases, phosphatases, etc.
B. Increased exposure to UV light increases the risk of mutation occurring.
Answer:
Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.
Explanation:
Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.
