Question: Q: What protects you from pathogens and keeps you healthy? Read this paragraph and choose the correct option from the provided answers: Your immune system usually protects you from pathogens and keeps you well. However, like any other body system, the immune system itself can develop problems. Sometimes it responds to harmless foreign substances as though they were pathogens. Sometimes it attacks the body's own cells. Certain diseases can also attack and damage the immune system and interfere with its ability to defend the body. Choices: - immunity system - health system - potent system - immune system A:
Answer: immune system

Question: Q: In experiments with garden peas, austrian monk gregor mendel described the basic patterns of what? Read this paragraph and choose the correct option from the provided answers: For thousands of years, humans have understood that characteristics such as eye color, hair color, or even flower color are passed from one generation to the next. The passing of characteristics from parent to offspring is called heredity . Humans have long been interested in understanding heredity. Many hereditary mechanisms were developed by scholars but were not properly tested or quantified. The scientific study of genetics did not begin until the late 19 th century. In experiments with garden peas, Austrian monk Gregor Mendel described the basic patterns of inheritance. Keep in mind that while we know about DNA and its role as the genetic material, Mendel did not know of the existence of DNA. Nor did he understand the concept of the chromosome or the process of meiosis, and yet, he was still able to correctly describe basic inheritance patterns. Choices: - behavior - preference - color - inheritance A:
Answer: inheritance

Question: Q: The flood of sodium ions through the symporter provides the energy that allows what to move through the symporter and into the cell? Read this paragraph and choose the correct option from the provided answers: Active transport pumps can also work together with other active or passive transport systems to move substances across the membrane. For example, the sodium-potassium pump maintains a high concentration of sodium ions outside of the cell. Therefore, if the cell needs sodium ions, all it has to do is open a passive sodium channel, as the concentration gradient of the sodium ions will drive them to diffuse into the cell. In this way, the action of an active transport pump (the sodiumpotassium pump) powers the passive transport of sodium ions by creating a concentration gradient. When active transport powers the transport of another substance in this way, it is called secondary active transport. Symporters are secondary active transporters that move two substances in the same direction. For example, the sodiumglucose symporter uses sodium ions to "pull" glucose molecules into the cell. Because cells store glucose for energy, glucose is typically at a higher concentration inside of the cell than outside. However, due to the action of the sodiumpotassium pump, sodium ions will easily diffuse into the cell when the symporter is opened. The flood of sodium ions through the symporter provides the energy that allows glucose to move through the symporter and into the cell, against its concentration gradient. Choices: - insulin - sucrose - mitochondria - glucose A:
Answer:
glucose
