Which of the following describes a boreal forest? A biome occurring at high northern latitudes that is dominated by conifers that can withstand the long, cold winters
A blome in tropical regions where rain falls seasonally and broad-leaved trees dominate
A blome dominated by broad-leaved trees that flower and grow in warm seasons, Inen drop their leaves and become
dormant during cold winters
A biome dominated by a multilayered forest that occurs where warm temperatures and continual rains allow plant
growth year-round

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.
