Which of the following statements best describes how conductors and insulators differ.
A. Conductors do not transfer heat well, insulators transfer heat well.
B. Conductors transfer heat well, insulators do not transfer heat well.

The answer is B because conductors transfer heat easily & insulators are mostly to keep heat away and cold in ..

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
