A biologist discovers a new animal in a marine environment that has hexagonal radial symmetry. Of the following methods, which will best help him classify this organism with the deuterostomes or with some other group such as the ctenophores, sponges, or placozoans?
A.) Dissect the animal to see whether or not it has a notochord. B.) Raise the animal in the lab and trace its embryological development. C.) Observe the animal's feeding behavior. D.) Analyze the animal's mode of reproduction.

B.) Raise the animal in the lab and trace its embryological development

Explanation:Embryological development is the process through which embryos forms and develop in animals,embryological development can also be termed as EMBRYOGENESIS. The best way classifying the organism will be by raising the organism in the lab,to understand the organism's Embryological development, this will help to know the embryonic stages and patterns of development which takes place in the organisms.

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.
