Answer

Brief Explanations:

  1. Dimethylmercury is toxic, and the 'T' symbol represents toxic substances in WHMIS symbols.
  2. Iron, gold, and oxygen are pure substances made of only one - type of atom, which are elements.
  3. The swim bladder in a fish is mainly used to regulate buoyancy, allowing the fish to move up and down in the water.
  4. Valves in devices like bicycle pumps and water taps are used to control the direction and amount of fluid flow, i.e., regulate the flow of fluids.
  5. Cleaning ancient paintings requires knowledge about solubility to choose appropriate cleaning agents that can remove dirt and contaminants without damaging the paintings.

Answer:

  1. C. T
  2. C. elements
  3. B. to regulate buoyancy
  4. B. regulate the flow of the fluids
  5. C. solubility
