Will give a brainlest -for rigth answer very easy look at the graph showing populations of different age ranges in mexico. which is a true statement? about half of mexico’s population is under the age of 20. most of the people of mexico are in their 30s and 40s. mexico has a growing population of elderly people.

Option A, About half of Mexico’s population is under the age of 20.

Explanation:

The demographic graph represented in this image depict an expansive population graph. An expansive population is one which has a large percentage of people in younger age groups. Here the base of the curve is wide and the top is narrow which means that the population has a high fertility rate with lower life expectancy.

Hence, option A is correct.

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.
