C. predation

Explanation:

The limiting factor that is being displayed when a fox chases a pika is predation.

Limiting factors can be referred to as those features in the environment which actually leads to the limitation in the growth, distribution or availability/abundance of an organism or population of organisms in an ecosystem.

In the predation limiting factor, as the population of the prey decreases, the population of the predator starts to decrease as well. In other words, we can say that one factor limits the growth of the other factor.

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.
