A(cid:374) a(cid:374)i(cid:373)al"s (cid:449)ork uses (cid:272)he(cid:373)i(cid:272)al e(cid:374)erg(cid:455) to ge(cid:374)erate (cid:373)ole(cid:272)ular order. Molecular order (the positions, shapes, and chemicals bonds of the molecules in your body) is what makes you who you are -> memories, thoughts (-- at the intra and intermolecular level) Yes, as they have the same function: a(cid:374)i(cid:373)als are like theseus" ship, e(cid:454)(cid:272)ept a(cid:374)i(cid:373)als are defi(cid:374)ed (cid:271)(cid:455) their stru(cid:272)ture right do(cid:449)(cid:374) to the microscopic level. In order to maintain identity, must maintain structural organization. Without energy, molecular structure disappears over time. A(cid:374)i(cid:373)als" (cid:271)odies are (cid:272)o(cid:374)sta(cid:374)tl(cid:455) i(cid:374) flu(cid:454), (cid:271)ut the(cid:455) perfor(cid:373) (cid:449)ork to (cid:373)ai(cid:374)tai(cid:374), re(cid:374)e(cid:449), a(cid:374)d resynthesize their molecular structure. Cells: tiny molecule factories that take raw materials and use energy to assemble and organize molecules. Cells require certain physical conditions to work properly (right temperature, ph, salinity etc. ) Main goal for animals is to maintain molecular structure.
