What is the founder effect?

sampling error that occurs during the establishment of a new population by a small number of migrants
natural selection that acts on the founders of a new population in their new, different environment
the frequencies of alleles in a population changing slowly over generations due to chance events
a period of rapid population growth that immediately follows some population bottlenecks

The answer is B, Natural selection that acts in the founders of a new population in their new, different environment.

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.
