The level of toxicity depends such ac a) the rate of absorptionExplanation / Answer
20) c- apoptosis is defined as the normal process of cell death
21) d- all of the above - the tissue responses to the chemical injury involve first degeneration followed by circulatory and inflammation changes and then neoplasia
22) a - Necrosis is the process of tissue destruction characterized by structural and biochemical changes
23) a- subchronic toxicity is defined as effects of single or multiple dose exposure during a 24 hr period
24) a - the cell membrane gets affected by disturbance in state of cell electrolytes so it is more coomon cellular target for chemical injury
26) b- apoptosis is defined as the active,orderly process for eliminating damaged or dead cells without inflammatory response
