So the answer is yes, the presence of the lactose molecule controls whether the operon is on or off.

Tetraploidy will occur.

The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.
The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.
Now as the gametes fuse, both the n becomes 2n and diploid state is regained.
But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
The nurse would most likely disagree with the patient. Pap smear is a diagnostic test that screens pre-cancerous or cancerous cells on the cervix, which is the opening of the uterus. It is recommended for women starting from the age 21 to regularly undergo this test, especially when sexually active. For the 49 year-old patient, she needs to undergo Pap smear test every 3 to 5 years. The patient should note that this test is used to track any abnormal cells in the cervix. When they do, early treatment would still be done in the hospital before it becomes even more serious. Hence, whether the patient took Pap smear tests regularly, she would still need the help of the hospital to treat it. It would only differ in the time of admittance.
