Which statement is correct concerning the process of ecological succession? shrubs will replace pines during succession. primary succession starts after a forest fire. after a disturbance, the community goes through a somewhat predictable set of changes until reaching a final state. planting pines in an abandoned farm field mimics the natural progression of species during succession.

Option (2).

Explanation:

Ecological succession is the change in the ecological community of the species with respect to time. Two  types of the succession are  secondary succession and primary succession.

The ecological succession includes various transitional stages before reaching to the climax community. The simple species acquires first and then the climax species is reached at the end of the succession. Different changes are involved in the formation of climax community.

Thus, the correct answer is option (2).

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.
