Answer the following question given this paragraph: The spleen is in the upper abdomen. It filters pathogens and worn out red blood cells from the blood, and then lymphocytes in the spleen destroy them. Q: What filters pathogens and worn out red blood cells from the blood? Choices: - the bladder - the stomach - the pancreas - the spleen A:
the spleen

an amorphous solid
Q: Answer the following question given this paragraph: sphincter, but the esophagus remains closed when there is no swallowing action. Acid reflux or "heartburn" occurs when the acidic digestive juices escape into the esophagus. Stomach A large part of digestion occurs in the stomach, shown in Figure 34.11. The stomach is a saclike organ that secretes gastric digestive juices. The pH in the stomach is between 1.5 and 2.5. This highly acidic environment is required for the chemical breakdown of food and the extraction of nutrients. When empty, the stomach is a rather small organ; however, it can expand to up to 20 times its resting size when filled with food. This characteristic is particularly useful for animals that need to eat when food is available. Q: What is the cause of the "heartburn" that occurs when acidic digestive juices escape into the esophagus? Choices: - toxic reflux - acidic buildup - acid pressure - acid reflux A:
A: acid reflux
Question: Answer the following question given this paragraph: Forensic Scientist Forensic science is the application of science to answer questions related to the law. Biologists as well as chemists and biochemists can be forensic scientists. Forensic scientists provide scientific evidence for use in courts, and their job involves examining trace material associated with crimes. Interest in forensic science has increased in the last few years, possibly because of popular television shows that feature forensic scientists on the job. Also, the development of molecular techniques and the establishment of DNA databases have updated the types of work that forensic scientists can do. Their job activities are primarily related to crimes against people such as murder, rape, and assault. Their work involves analyzing samples such as hair, blood, and other body fluids and also processing DNA (Figure 1.13) found in many different environments and materials. Forensic scientists also analyze other biological evidence left at crime scenes, such as insect parts or pollen grains. Students who want to pursue careers in forensic science will most likely be required to take chemistry and biology courses as well as some intensive math courses. Q: What type of science is the application of science to answer questions related to the law? Choices: - ecology - biologic - physics - forensic A:
Answer: forensic

semiconductors
Q: Answer the following question given this paragraph: Sequencing the human genome has increased our knowledge of genetic disorders. These are diseases caused by mutations. They may be caused by single gene mutations or the failure of chromosomes to separate correctly during meiosis. Q: What causes genetic disorders? Choices: - parasites - proteins - pollution - mutations A:
A: mutations
