In a few generations, this population of beetles changed. A group of bugs includes 13 black bugs and 4 green bugs. After a few generations, there are 13 green bugs and 4 black bugs. Which is the most likely explanation for the change? The beetle population moved to a greener habitat. A natural disaster almost caused the extinction of the population. The beetle population’s food sources decreased dramatically. A mutation resulted in a new color of insect.

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.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
