Answer:
fish.
various types of eggs.
dairy products, such as cheese, milk, and whey.
red meat from cows, bison, and deer.
poultry from sources such as chickens, turkeys, and quails.
meat from less common sources, including boars, hares, and horses.
Animal proteins, such as meat, eggs, and milk, are complete proteins, meaning they provide all of the essential amino acids our body needs. Animal products provide the highest-quality protein sources.
Explanation:
Iodine -131 is used to detect thyroid malfunction in the human body as iodide salts exploit the mechanism of absorption of iodine by the normal cells of the thyroid gland
Answer:
C2H5OH(l) + O2(g) → CO2(g) + ?H2O(l)
The coefficient should be 3
Explanation:
C2H5OH(l) + O2(g) → CO2(g) + ?H2O(l)
The chemical equation is a reaction between ethanol and oxygen . The reaction yield is carbon dioxide and water. Balancing the chemical equation requires one to make the number of atoms on the reactant side be equal to the number of atoms on the product side.
C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)
The hydrogen atom on the left hand side of the equation is 6. Therefore, the number of atom of hydrogen should be 6 on the right hand side. The number of oxygen atom on the left hand side is 7. Therefore, the number of Oxygen atom on the right hand side should 7 . Oxygen atom in carbon dioxide(right hand side) is 4 atoms, therefore, it requires 3 atoms of oxygen to make the oxygen atoms 7.
Using 3 as the coefficient of water in the equation will make hydrogen 6 and oxygen 3 .Adding the 3 oxygen to the already 4 atoms of oxygen in carbon dioxide will make oxygen 7 atoms
