Solution Steps

Step 1: Identifying Carbohydrates

Carbohydrates are organic compounds characterized by a general formula of (CH2O)n, signifying a hydrate of carbon. They consist of carbon, hydrogen, and oxygen, with a 2:1 hydrogen-to-oxygen ratio.

Step 2: Analyzing the Options

The first option shows a segment of a DNA molecule, composed of nucleotides. Nucleotides contain nitrogenous bases, deoxyribose sugar (a carbohydrate), and phosphate groups. The second option displays a molecule with a carboxyl group (COOH), suggesting it's a carboxylic acid. The third option, CH2OH, represents the simplest carbohydrate, a monosaccharide.

Final Answer:

CH2OH represents a carbohydrate.

Focusing System of the Eye Three events occur to bring the image into focus on the retina: accommodation, pupil constriction, and convergence. Test your knowledge about these events by selecting 'True' or 'False'. Accommodation is as a result of parasympathetic stimulation from the Optic nerve (l). In accommodation, the lens becomes more convex (spherical) in shape. One reason accommodation becomes more difficult as an object is brought closer to the eye because the lens cannot become any more flattened. When we look at a close-up object, the pupil diameter decreases. When the pupil is constricted, the light entering the eye tends to pass through the center of the lens than through the edges of the lens. The smaller the pupil diameter, the more light enters the eye and is directed toward the retina. Both pupils can pick up the light rays when the eyes are looking forward. Convergence states that eyes are rotated medially as an object moves closer. In convergence, rotation of the eyes is accomplished by the medial oblique muscles.
