Answer:

b. a capsule

Explanation:

The capsule is mainly made up of polysaccharides and surrounds many bacteria. Capsule staining includes mixing of the bacterial cells with dye and spread out in a thin film on a slide. After air-drying, the cells appear as light-colored structures present in a relatively dark blue-black background. This occurs since the dye particles cannot penetrate either the cell or its capsule. Therefore, the given slide with a colorless ring around the cells in a dark background represents the presence of a capsule around the observed cells.

Alchen [17]
<span>Food molecules like lipids, proteins and polysaccharides are broken down enzymatically via digestion process, which occurs in our intestine cells (digestive system). Those large polymeric molecules are broken down into their monomer subunits—proteins into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol. Formed small organic molecules are now ready for the oxidation (a process that produces ATP and consumes O2) which occurs partly in the cytosol and in the mitochondrion. Oxidation processes include glycolysis and citric acid cycle which are differently required in different tissues. Nervous system (nerve cells) rely almost entirely on a constant supply of <span>glucose<span> from the bloodstream. In contrast, liver cells supply glucose to actively contracting muscle system which needs a lot of ATP energy.</span></span></span>
