A group of scientists designed a clinical study to investigate the effects of cholesterol deficiency in humans. For the duration of the 8-week study, the adult subjects must live in a special research unit of a hospital. The only food the subjects can consume is a synthetic formula that contains all known nutrients, except cholesterol. Based on this information, you would expect:a. 100% of the subjects to show signs and symptoms of cholesterol deficiency within the first 3 weeks of participating in the study. b. about 50% of the subjects to show signs and symptoms of a cholesterol deficiency within the first week of the study. c. none of the subjects to show signs and symptoms of a cholesterol deficiency during the entire study. d. about 10% of the subjects to show signs and symptoms of a cholesterol deficiency within the first week of participating in the study.
