A)Hyperplasia is an increase in density or number of normal cells in response to stress-in this case, the increased demand for oxygen. Cells that lose fluid will shrink in size. Muscle damage occurs because of inadequate nutrition, not because of hyperplasia. Heart muscle cells may become hyperplastic because of increased metabolic demands, not decreased metabolic demands.
