ax = the total number of individuals observed in the population in stage x. lx = survivorship to stage x. dx = proportion of the original cohort dying during stage x. qx = mortality rate for individuals in stage x. kx = killing power of stage x (log10 ax â log10 ax+1) Fx = number of offspring produced in stage x.
Regular Cheese. A slice of regular Kraft cheese, made from whole milk, contains 60 calories. Sixty percent of those total calories -- or 36 calories -- come from the 4 grams of fat. You will get protein from this same slice; 3 grams to be exact. That amounts to 12 calories from protein or 20 percent of the overall calories.
Although a bread's variety and size of slice affect its caloric value, the U.S. Department of Agriculture reports that a slice of white bread contains 74 calories, while a slice of whole-wheat bread has 81 calories. Sliced, luncheon meat-style ham contains 46 calories per slice, and a single slice of low-fat American cheese has 38 calories.
