1. Inhalation of fragrances or fumes from fixatives and solvents,
2. Chewing on a plastic toy by a child that develops small openings in the plastic, which provides a space for the chemical to get leached from the toy into the mouth of the child.

Answer:
Physical changes can easily be reversed but chemical changes cannot because in physical change only state is changed while in chemical change, new substances are formed. For example, when water in liquid form is condensed, it changes into solid form (ice). It is a physical change because water in liquid and solid have the same chemical formula only arrangement of molecules are different. Burning of wood is a chemical change because new substances i. e. carbondioxide and heat is produced.
Genetic diversity
Explanation:
Sexual reproductions, mutation, and crossing-over generates a wide range of genetic diversity within a population.
- Sexual reproduction is a type of reproduction in which gametes fuses to produce a fertile and viable offspring.
- Mutation is the process of altering genetic sequences in population to production new breeds called mutants.
- Crossing-over is the exchange of chromosomes between two homologous pairs.
All these processes ensures that a pool of diverse gene exists within a population in order give competitive and adaptability advantage to organisms.
