Maria is concerned because she has been exposed to a small amount of radiation during an x-ray. what is her doctor most likely to tell her

A. Radiation from X-rays is not a mutagen unless you have X-rays every day.

Explanation:

Getting a little of radiation from X-rays barely causes any effects. Getting tanned constantly with UV lights and really just spending time outside with no protection can cause the mutation to trespass the skin layers and cause a mutation which usually ends up as skin cancer.

is this a psat question, if so do not cheat try your best.

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.
