If a total of 2000 kcal were consumed (250 grams of carbohydrates, 66 grams of fat, and 102 grams of protein), what percentage of energy comes from carbohydrates, fat, and protein?
a. 30% carbohydrate, 50% fat, and 20% protein
b. 50% carbohydrate, 35% fat, and 15% protein
c. 20% carbohydrate, 30% fat, and 50% protein
d. 50% carbohydrate, 30% fat, and 20% protein

D)50% carbohydrate, 30% fat , and 20% protien

Explanation

1 gram of carbohydrate and protien contains almost 9 kcal while 1 gram of lipid contains 9 kcal.

As there is a total of 2000 Kcal. 250 g of carbohydrate will contain 1000 kcal (250 g * 4 =1000kcal). Similarly 66g of fat will contain (66*9=594kcal) .While 102 g of protiens will contain (102 * 4=408kcal). As the percentages are counted by formula Individual calories /total calories * 100. carbs contribute 50% as per the fromula 1000/2000 *100 .Similarly fat contributes 30% as per formula 594/2000 * 100 while protiens contributes 20% as per the same formula 408/2000 * 100.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
