What kind of food contains lots of carbohydrates answers?

The correct answer would be - plant-based food such as grains, fruits, and vegetables are a great source of carbohydrates.

Explanation:

Carbohydrate is the biomolecule that is present in the foods and living tissues containing sugars, starch or cellulose. These are the biomolecule with carbon, hydrogen, and oxygen and the ratio of hydrogen and oxygen is 2:1 in them.

The great source of carbohydrates is plant-based foods especially grains like wheat, rice, barley. Other than grains fruits and vegetables are also great sources of carbohydrate.

Thus, the correct answer is - plant-based food such as grains, fruits, and vegetables are a great source of carbohydrates.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
