As a college student, you are trying to be healthy and calorie conscious by making yourself a lettuce and tomato sandwich for supper. after making the sandwich, you decide it needs something extra. in the store, you find bacon (20 g of fat), lean chicken (20 g of protein), or sprouts (20 g of carbohydrates) that you would add. which of these would provide the lowest calorie count for your sandwich?
a. the sprouts would add the fewest calories.
b. both meats would be identical if you add 20 g of each.
c. the sprouts or the chicken would add the fewest calories.
d. the bacon would add the fewest calories.
e. the chicken would add the fewest calories.

The correct answer is C. The sprouts or the chicken would add the fewest Calories.

Explanation:

The calories refer to the amount of energy food contain, these are necessary to design nutritions plans, diets and keep a healthy weight. Additionally, the number of calories depends on the type of food, the size of it and whether it contains mainly fat, protein, carbohydrates, fiber, etc. In this way, 1 gram of fat contains around 9 calories and 1 gram of protein or carbohydrates contains around 4 calories. This implies, in the case presented the sprouts or the chicken add fewest calories as the 20 grames would be equivalent to around 80 calories while the bacon would be equivalent to 160 calories.

In homeostasis fashion, cells undergo balanced cell division and programmed cell death (apoptosis) through regulated signalling.This maintains tissue integrity. On the one hand, Proto-oncogenes promotes cells proliferation. On the other hand, tumors suppressors inhibit cell growth and division especially in cells with damaged dna.
Therefore mutations on these oncogenes could result to uncontrolled cell proliferation. Cancer cells also overexpress angiogens that results to proliferation of blood vessels in tumors. This contributes to their metastasis in the body.
