what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part F

What scientists are doing incorrectly is sharing the work table, having test tubes with chemicals and food on the same table.

Explanation:

The image shows two scientists sharing the same work table, where there are also chemicals in test tubes and food, resulting in an incorrect practice.

In this case, to maintain the biosafety procedures in a laboratory, it is necessary to:

Biosafety in a laboratory is essential for efficient work and to avoid unnecessary accidents.

It is important to follow these procedures so that the work is fluid, to avoid unnecessary chemical spills, biocontamination and accidental poisoning in the laboratory area.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
