Q: Nutrition and diet affect your metabolism. more energy is required to break down fats and proteins than this? Read this paragraph and choose the correct option from the provided answers: 24.7 Nutrition and Diet Nutrition and diet affect your metabolism. More energy is required to break down fats and proteins than carbohydrates; however, all excess calories that are ingested will be stored as fat in the body. On average, a person requires 1500 to 2000 calories for normal daily activity, although routine exercise will increase that amount. If you ingest more than that, the remainder is stored for later use. Conversely, if you ingest less than that, the energy stores in your body will be depleted. Both the quantity and quality of the food you eat affect your metabolism and can affect your overall health. Eating too much or too little can result in serious medical conditions, including cardiovascular disease, cancer, and diabetes. Vitamins and minerals are essential parts of the diet. They are needed for the proper function of metabolic pathways in the body. Vitamins are not stored in the body, so they must be obtained from the diet or synthesized from precursors available in the diet. Minerals are also obtained from the diet, but they are also stored, primarily in skeletal tissues. Choices: - vitamins - electrolytes - minerals - carbohydrates A:
(A).
carbohydrates

Q: What has increased in the atmosphere throughout the history of the earth? Read this paragraph and choose the correct option from the provided answers: Oxygen has increased in the atmosphere throughout the history of the earth. Note the logarithmic scale, which indicates great increases after first photosynthesis (in bacteria) and then land plants evolved. Related geological events: A = no oxidized iron; B = oxidized iron bands in seabed rock - evidence for O 2 in the oceans; C = oxidized iron bands on land and ozone layer formation- evidence for O 2 in the atmosphere. Choices: - nitrogen - wind - carbon - oxygen A:
(A).
oxygen

Q: What is a feature that prokaryotes lack? Read this paragraph and choose the correct option from the provided answers: No doubt you've had a sore throat before, and you've probably eaten cheese or yogurt. If so, then you've already encountered the amazing world of prokaryotes. Prokaryotes are single-celled organisms that lack a nucleus. They also lack other membrane-bound organelles. Prokaryotes are tiny. They can only be viewed with a microscope (see Figure below ). But they are the most numerous organisms on Earth. Without them, the world would be a very different place. Choices: - epidermis - cell wall - plasma - nucleus A:
(A).
nucleus
