Answer to Question 1

C
Dietary antioxidants, found in fruits and vegetables as well as some other foods, may help pro-tect against carcinogenesis. Electrolytes, amino acids, and monounsaturated fatty acids are all important in maintaining good nutritional status but do not help protect against carcinogenesis.

Answer to Question 2

A
The DNA of the cell undergoes mutation in the initiation stage of carcinogenesis. Promotion is the second stage in which abnormal cell growth occurs. Progression is the third stage in which cancer cells spread beyond their original location. Metastasis is formation of cancer in secondary sites.
