Answer:
A Neutron and a Hydrogen Atom
Explanation:
Hydrogen atom having an atomic mass of 1.008 amu consists of one proton and one electron. Hence, the +ve and -ve charges cancels out and makes the hydrogen atom a neutral specie.
Also, we know that neutron is neutral sub particle while, proton and electron are positively and negatively charged respectively. Therefore, a neutral neutron having no charge becomes equal to hydrogen atom having zero charge due to cancellation of both +ve and -ve charges.
Answer:
Energy in foods is provided by macro-nutrients.
Explanation:
Nutrients are “environmental substances” used for growth, energy, and bodily functions of the organisms. Those nutrients that are required in larger amounts are called macro-nutrients.
There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in form of “calories”. For example:
- In carbohydrates, there are '4 calories' of energy per gram.
- In proteins, there are '4 calories' of energy per gram.
- And in lipids, there are '9 calories' of energy in one gram.
This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.
