Answer the following question given this paragraph: The inheritance of traits is not always as simple as Mendel's rules. Each characteristic Mendel investigated was controlled by one gene that had only two possible alleles, one of which was completely dominant over the other. We now know that inheritance is often more complicated than this. In blood types, for example, there are actually three alleles instead of two. And some traits even have more than three alleles. Q: What measures the amount of matter in an object? Choices: - concentrations - amounts - weight - mass A:
mass
Answer the following question given this paragraph: Diffusion can occur across a semipermeable membrane, such as the cell membrane, as long as a concentration gradient exists. Molecules will continue to flow in this manner until equilibrium is reached. At equilibrium, there is no longer an area of high concentration or low concentration, and molecules flow equally in both directions across the semipermeable membrane. At equilibrium, equal amounts of a molecule are entering and leaving a cell. Q: Diffusion can occur across a semipermeable membrane, such as the cell membrane, as long as a what exists? Choices: - polarity - parity - differential - concentration gradient A:
concentration gradient
Q: Answer the following question given this paragraph: Scientists use the scientific method to answer questions. The scientific method is a series of steps. These steps help scientists (or even just people!) investigate a question. Q: What method do scientists use to answer questions? Choices: - inquisitive method - regulatory method - solutive method - scientific method A:
A: scientific method
Question: Answer the following question given this paragraph: Q: Plasmodesmata passes through what part of plants? Choices: - nucleus - cell ridges - cytoplasm - cell walls A:
Answer: cell walls
*Question*
Answer the following question given this paragraph: 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. Q: Nutrition and diet affect your metabolism. more energy is required to break down fats and proteins than this? Choices: - vitamins - electrolytes - minerals - carbohydrates A:
**Answer**
carbohydrates
