Aresearcher wishes to place electrodes in the brain so that existing motor activity can be used to control an artificial hand designed for amputees. the researcher should place the electrodes in the

The researcher should place the electrodes in the frontal lobe of the brain.  Since the goal of the researcher is to control an artificial hand for disabled people, the frontal lobe is the best place to set the electrodes because it controls the motor function of the body.

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.
