Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
Answer: True
Sometimes the use of condoms can't prevent STIs(sexually transmitted infections) because of the manufacturer fault. STIs that caused by lice is not protected too because the condom doesn't cover hair. Other than that, a condom provides a good physical barrier that prevents diseases that transmitted body liquid.
The fundamental sequence of events in mitosis is the same as in meiosis (in meiosis it happens twice). Both processes include the breakdown of the nuclear membrane, the separation of genetic material into two groups, followed by cell division and the reformation of the nuclear membrane in each cells.
