C. Because the Moon is made out of rocks.
B. Because the Moon is much closer to Earth.
D. Because the Sun’s gravity is weaker.

B

Explanation:

the tides are controlled by the moons gravitational pull because it is closer though the sun is bigger it is also the middle of our system and farther away from our planet

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.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
