Hospitals are interested in ocean research because

1. the ocean floor is rich with oil and natural gas

2. oysters are a a valuable source of copper

3. powerful anesthestics are found in marine organisms

4. fish are a valuable source of protein

3. powerful anesthestics are found in marine organisms  

Explanation:

Oceanography is the study of all aspects of the oceans including the physical, chemical occurring in the oceanic water, the study of the marine life, and seafloor geology.

3. powerful anesthestics are found in marine organisms is the correct option. As the hospitals can conduct research on how marine organisms can be useful for production of medicines. As the aim of the hospital and other medical institute is to find the relevant sources of plants and animals derivatives to use them in medication.

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.
