In this case, the bacteria continues to grow and multiply in the present of the antibiotic drug. Antibiotic resistant usually occur when a bacteria has develop a variation that makes it possible for it to inactivate the antibiotic drug that is used against it.

Waxy cuticle decrease evaporation from leaves.
Explanation:
The mules are the hybrid of the horse and donkey. The horse female gamete cell contains 32 chromosomes whereas the donkey sperm cell contains 31 chromosomes.
The hybrid produced shows that the donkeys and horses shared the recent common ancestor.
The mules are infertile organisms as their gametes are not formed properly due to the difference in the number of chromosomes of the male and female gamete.
The gametes are produced by the process of meiosis which involves the pairing of homologous chromosomes but chromosomes fail to pair because of one extra chromosome which fails to for homologous pair.
The mitosis is possible in the organism as the mitosis process does not involve the pairing.
