Many plants that grow in cooler climates where freezing temperatures are common have needles instead of leaves. These needles have less surface area than a broad leaf, and are coated in a waxy coating. Why are needles common leaf adaptations in cooler climates?

Explanation:

Needle are common leaf adaptation in plants crowing in cooler climates because needle like shape do not allow snow to stay on it for longer. The shape reduces the surface area preventing the loss of water through transpiration. A waxy coat on the surface also prevents the loss of water.

Adaptations are certain traits that allow survival benefits to an organism in its native habitat. Animals and plants both show adaptation. Adaptation can be morphological or anatomical.

i think the answer is gold im not entirely sure

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.
