Relative molecular mass or RMM is the answer.
Answer:
A) dietary fiber isn't used by the body.
Explanation:
The food we eat contains certain nutritional contents that provides energy, measured in calories (CAL) to the body. A procedure called BOMB CALORIMETRY can be used to determine the energy contents of these foods. The energy-supplying macromolecules contained in food substances we eat are carbohydrate, protein, fats etc.
Bomb calorimetry uses the method of burning the food substance in a device called bomb calorimeter, and measure the caloric content of the burnt food. Bomb calorimetry measures all the present calories in a food substance, which can include dietary fibers. Due to this reason, it is considered a poor choice in determining the number of nutritional calories in a food substance.
Dietary fibers are indigestible carbohydrates that cannot be broken down and used by the body. They pass along the alimentary canal until they are egested. Hence, they are no source of nutrients to the body. Since bomb calorimetry measures all calories including dietary fibers, it is said to overestimate the caloric content of food substances.
The accepted model of the atom was changed. JJ Thomson discovered the electrons and performed experiment using the cathode ray tube. The model before his did not have electrons so the model was changed. Hope this helps
1.) The modern atomic theory has been updated over the years..
the correct option is:
C. The changes make the theory stronger because it has been tested and edited multiple times, making it more durable.
2. In Rutherfords experiment,Based on Thomson's plum pudding model of the atom, what did Rutherford expect to happen;
A. All the alpha particles would be deflected by the foil because of the even distribution of mass and charge throughout the atom.
According to Thomson's plum pudding model of the atom the positive and negative charges are evenly distributed.
