1. Develop an interactive computer program that returns the user's basal metabolic rate, oxygen uptake rate, carbon dioxide production rate, pulse rate, and breathing rate when the user inputs his or her mass or weight.

2. Develop an interactive computer program that outputs the energy conversion efficiency of a person or an animal. The user must be prompted for input data regarding work performed, energy output resulting in increases in potential or kinetic energies, and changes in body total internal energy. You may assume that the specific internal energy of the body is constant for activities that occur over short time periods.
