As you study two closely-related bird species, the yellow and orange warblers, you notice that each species seeks many different types insect prey (midges, caterpillars, beetles, leafhoppers, and wasps) in areas without the other species. However, where their ranges overlap, the yellow warbler mostly eats caterpillars, midges and leafhoppers and the orange warbler mostly eats beetles and wasps, as well as some spiders. You have discovered an example of .

i think that the best answer would be c.

tell me if im wrong : )

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

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.
