To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.
Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.
500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal
From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:
2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%
Plate tectonic theory can be made up of two things. The two things
that it is made of are all oceanic lithosphere or all continental
lithosphere.
Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
+ not having enough food for everyone
+ how many people migrate
+ birth/death rates
+ how much water there is
+ how much nutrients/minerals are available
+ how much trees/oxygen is available
