Typical apples contain 84% water, 14% carbohydrates and 0.5% fat, a total of 98.5% content in the apple while the rest are possibly some fibers like the skin and solids that cannot be eaten such as seeds. To calculate the calorie content of the apple on the basis of 255 g, know first the weight of carbohydrates and fats in the apple and find their contribution to energy burned and water cannot be burned since it does not contain a carbon atom

Carbohydrate content : ((255 g*0.14)* 4 cal/g = 142.9 cal
Fat content : ((255 g*0.005)*9 cal/g = 11.475 cal
Total: 154.375 cal on a 255 g apple

Answer:

<h2>An apple provides a total of 136.125 calories.</h2>

Explanation:

We know that

  • An apple weighs 225 grams, it has 84% water, 14% carbohydrate and 0.5% fat.
  • Also, typical foods produce 9 calories per gram for their fat content and 4 calories per gram for their protein and carbohydrate content.

So, to find the answer, we need to know the number of grams that is fat and carbohydrate.

Using the given percentages, we have

Fat: (0.5\%)(225g)=0.005(225g)=1.125g

Carbohydrate: (14\%)(225g)=0.14(225g)=31.5g

An apple has 1.125 grams of fat and 31.5 grams of carbohydrates.

If there are 9 calories per gram of fat, the total number of calories in this case would be

Fat: 1.125g(9\frac{cal}{g})= 10.125cal

If there are 4 calories per gram of carbohydrate, the total number is

Carbohydrate: 31.5g(4\frac{cal}{g})= 126cal

Therefore, an apple provides 10.125 calories from fat and 126 calories from carbohydrates, for a total of 136.125 calories.

Sloan [31]

Answer:

The answer to the question: Introspection was the structuralists´ research method of choice. However, it was criticized by non-structuralists and ultimately fell by the wayside. Which of the following is not a reason that introspection was criticized? Would be, A: Introspectionism involved the study of conciousness.

Explanation:

The school of Structuralism in psychology was first started by Edward B. Titchener, a student of Wilhelm Wundt, considered to be the founder of psychology as the science that studied human behavior and mental processes. This school used as its most important tool the technique of introspection, which aimed at discovering the basic components of human thought and human conciousness, to understand the whole. This school, particularly due to the technique of introspection, was highly criticized by other schools of psychology that emerged later on, especially because of its inadequacy to actually explain human behavior, since it was highly reliant on subjective perceptions of a stimulus. What they were NOT criticized for, though, was for being a school that studied human conciousness, because this was precisely what they did; they studied human conciousness through the use of introspection.

When trying to lose weight how many calories should be eaten verse calories burned?
Delicious77 [7]

Answer:

Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, it's estimated that you need to burn about 3,500 calories to lose 1 pound. So, in general, if you cut about 500 to 1,000 calories a day from your typical diet, you'd lose about 1 to 2 pounds a week.

Excretes salts from its surface.Responsible for excreting carbon dioxide.
strojnjashka [21]

Answer:

The Human Excretory System

Explanation:

The Human Excretory System is crucial in removing or discharging wastes from the body. Wastes may come in the form of urine, earwax, excrement, sweat, carbon dioxide, etc.

The "skin" is part of the Excretory System that is responsible for removing<em> salts</em> from its surface in a process called<u> sweating</u>. On the other hand, the "lung" is responsible for excreting <em>"carbon dioxide</em>." Having high levels of this element in the blood will lead to <u>failure of the respiratory system</u>.
