The approximate energy yield of carbohydrates is 4 calories/gram; fats yield about 9 calories/gram, and proteins about 4 calories/gram. jack and sarah consumed the following for lunch: jack—100 grams protein, 20 grams fat, 75 grams carbohydrates; sarah— 75 grams protein, 10 grams fats, 75 grams carbohydrates. how many calories each did jack and sarah consume

Calories consume by Sarah 690 cal.

Calories consume by jack 880 cal.

Explanation:

For jack

Mass of carbohydrate = 75 g

Mass of protein = 100 g

Mass of fats = 20 g

For Sarah,

Mass of carbohydrate = 75 g

Mass of protein = 75 g

Mass of fats = 10 g

Solution:

The average calories content of

Protein 4 cal/g

Carbohydrate 4 cal/g

Fat 9 cal/g

Then,

First of all we will calculate the calories consume by jack.

100 g protein × 4 cal/g =  400 cal

20 g fat × 9 cal/g = 180 cal

75 g carb. × 4 cal/g = 300 cal

              Total calories = 880 cal  

Calories consume by Sarah.

75 g protein × 4 cal/g =  300 cal

10 g fat × 9 cal/g = 90 cal

75 g carb. × 4 cal/g = 300 cal

              Total calories = 690 cal  

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

explanation:

no u

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
