Yes, but they are tubular organs and like all other organs are made up of tissues
Answer:
D. Surface tension.
Explanation:
Surface tension is defined as the energy required to increase the surface area of a liquid by a unit amount.
The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:
A molecule in a liquid experiences cohesive forces with other molecules in all directions while molecules at the surface of a liquid experiences only net inward cohesive forces.
Word Equation: Barium chloride solution reacts with sodium sulfate solution to produce sodium chloride and barium sulfate.
Pressure can affect the boiling pressure of a substance
as when pressure increases the particles are closer together and so require more energy to boil therefore increasing the substances boiling point
