Answer:
p53 helps the cells from passing on mutations that lead to DNA damage. Hence, it is known as the guardian angel of the cell as it helps fight against cancer. However, if p53 becomes defective or missing, then the mutations will lead to cancer.
Mutations in the p53 can also cause the tumor-suppressing genes to convert into tumor causing genes. Hence, mutations in such kind of genes can be very harmful for the body.
Most of the neuron cells in our brains are interneurons
Substances and exposures that can lead to cancer are called carcinogens. Some carcinogens do not affect DNA directly, but lead to cancer in other ways. For example, they may cause cells to divide at a faster than normal rate, which could increase the chances that DNA changes will occur.
Answer:
Choice C. Sodium bicarbonate acted as a pH buffer in Solution 2.
Explanation:
Sodium carbonate is used as pH buffering agent. Buffering agent is a type of solution which contains weak base or acid which stabilize the solution when another strong acid or base is added to the solution. If acid is added, the weak base that is present in the solution reacts with it and when base is added, weak acid reacts with it.
