Answer:
Bringing healthy meals to the table can be difficult if you are trying to save money. Consider serving low-budget meatless meals once or twice a week. Meatless meals are made from beans, lentils, vegetables, and whole grains. These plant-based proteins tend to be less expensive and offer more health benefits than meat.
Explanation:
A diet based on plant-based products, in which fruits, vegetables, cereals, beans, legumes and nuts stand out, is rich in fiber, vitamins and other nutrients. In addition, non-meat eaters (vegetarians) generally eat fewer calories and fat, have less weight, and have a lower risk of heart disease than non-vegetarians.
Even reducing meat intake has a protective effect. Research indicates that those who eat red meat are at increased risk of heart disease, stroke, or diabetes. Processed meats also increase the risk of dying from these diseases. Also, what you don't eat can also affect your health. Diets reduced in nuts, seeds, shellfish, fruits and vegetables also increase the risk of death.
Answer : B) In step 2, there was a chemical change which was observed in sugar.
Explanation : In A step 2 there was a physical change that was seen. By just boiling the dissolved salt solution salt was obtained. Therefore, it is a physical change. In B step 2 there was a chemical change seen as sugar solution was thickened and turned brown. It was not obtained in its original form; there was a chemical reaction that took place during sugar evaporation. As chemical change is the one where the reaction is irreversible.
Therefore only in B step 2 there was a chemical change that was observed.
