What are some of the qualitative characteristics of the lens? How might those characteristics of the lens help with the focusing of light?

Explanation:

The lens is the biconvex structure of the eyes that help to refract light Ray's and focused it on the retina.

The lens is made up of transparent tissues which is between Iris and pupil which is an anterior segment of the eyes. The lens focuses light through vitreous humor which is a fluid around the retina. When the eyes focuses distant object, the lens becomes flattened in shape, the diameter either increase or decrease. The retina receive the images the cornea focuses through the lens and the images is transmitted as electrical impulses which is sent to the brain for interpretation.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
