Astroke causes a loss of brain function due to disturbance in the supply of blood to the brain. the result can be loss of certain bodily functions based on the specific area of the brain that was affected, such as improper function of limbs on one or both sides of the body.

describe another example of how a malfunction of one tissue can affect the function of another tissue.

In case if one tissue stops functioning, then the rest of the tissues will also stop functioning. For example, if one cannot feel the heat of a fire, then the nervous system would not possess the tendency to inform the brain that the person is hurting. Various tissues function in combination and require the other tissues to function appropriately. Thus, if one of the tissues is not working the other stops to function as well.

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.
