If a scientist collects evidence that questions the basics of a scientific theory, this means the theory is a) flawed to the point of being invalid b) going to be refined by further investigation c) going to be proven wrong d) not based on fact or evidence

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

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.
