Explanation:
If an organism has specialized cells, then the cells performs specific jobs.
A group of cells that performs a specific job is called tissues.
- In higher organisms, cells are specialized for specific purposes in them.
- This is to ensure that cells are optimized to carry out certain functions.
- Specialization of cells usually occurs by cellular differentiation when an organism begins to form.

Answer:what are the options????
Explanation:
The vapor pressure of a compound refers to the pressure generated by the vapour of a compound in equilibrium with its condensed stage. The major determinant of a compound vapour pressure is temperature. The vapour pressure of an aqueous solution of sodium chloride will be lower than that of pure water. This is because, dissolution of solute in a solvent always reduces the vapour pressure of the solution as a result of interactions between the molecule of the solute and the solvent. Thus, a pure compound will always have a higher vapour pressure than a solution.
