Please Help The article talks about two main ways to define life. One definition focuses on self-organization and self-maintenance. The other definition focuses on self-replication and evolution. Some obligate intracellular bacteria cannot propagate without a host cell. Do these bacteria meet the definitions of life described? Why or why not? How do these bacteria differ from viruses?

i don't know. if i were you, i would search it up online : d

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.
