Q1. When studying cell division in tissue samples, scientists often compute a mitotic index, which is the ratio of dividing cells to the total number of cells in the sample. Scientists frequently calculate mitotic index to evaluate the growth rates of different types of tissue. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue?
Q2. Exposure to occupational hazards such as coal dust, silica dust, and asbestos may lead to fibrosis. Or scarring of lung tissue. With this condition, lungs become stiff and have more "recoil." What will happen to TLC and VC under these conditions?
