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.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
