Mutations DUH it keeps saying Mutations over and over

Explanation:

B

Explanation:

The arrow travels from a cell to a cancerous tumor. The arrow is labeled with mutations so that’s the cause. On a more specific level, cancer is a group of cells but that’s not the cause, because we need cells to survive. Genes are pieces of dna which we also need to survive, because dna makes us who we are. That only leaves mutations

depends on if you on plato or not

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.
