Explanation:
The liver plays a crucial role in carbohydrate metabolism, storing excess glucose as glycogen and releasing it when blood sugar drops. The spleen acts as a blood filter, removing old, damaged, or abnormal red blood cells and storing platelets. The appendix is a small, blind-ended tube attached to the cecum; it has no significant role in human digestion and is considered a vestigial organ. Thus, statements 1 and 2 are correct.

Creutzfeldt-Jakob disease (CJD) is a rare, fatal brain disorder caused by misfolded prion proteins (PrP^Sc), which are infectious protein particles lacking nucleic acid. Rabies, polio, and influenza are caused by viruses. Prions cause spongiform encephalopathies like mad cow disease (BSE).
