Answer the following question given this paragraph: Compounds like sodium chloride form structures called crystals. A crystal is a rigid framework of many ions locked together in a repeating pattern. Ions are electrically charged forms of atoms. You can see a crystal of sodium chloride in the Figure below . It is made up of many sodium and chloride ions. Q: Compounds like sodium chloride form structures called what? A:
OPTIONS:
- ions
- microorganisms
- hydrocarbons
- crystals

Answer: crystals

Question: Answer the following question given this paragraph: Immunologist The variations in peripheral proteins and carbohydrates that affect a cell's recognition sites are of prime interest in immunology. These changes are taken into consideration in vaccine development. Many infectious diseases, such as smallpox, polio, diphtheria, and tetanus, were conquered by the use of vaccines. Immunologists are the physicians and scientists who research and develop vaccines, as well as treat and study allergies or other immune problems. Some immunologists study and treat autoimmune problems (diseases in which a person's immune system attacks his or her own cells or tissues, such as lupus) and immunodeficiencies, whether acquired (such as acquired immunodeficiency syndrome, or AIDS) or hereditary (such as severe combined immunodeficiency, or SCID). Immunologists are called in to help treat organ transplantation patients, who must have their immune systems suppressed so that their bodies will not reject a transplanted organ. Some immunologists work to understand natural immunity and the effects of a person's environment on it. Others work on questions about how the immune system affects diseases such as cancer. In the past, the importance of having a healthy immune system in preventing cancer was not at all understood. To work as an immunologist, a PhD or MD is required. In addition, immunologists undertake at least 23 years of training in an accredited program and must pass an examination given by the American Board of Allergy and Immunology. Immunologists must possess knowledge of the functions of the human body as they relate to issues beyond immunization, and knowledge of pharmacology and medical technology, such as medications, therapies, test materials, and surgical procedures. Q: What is the term for physicians and scientists who research and develop vaccines and treat and study conditions ranging from allergies to aids? A:
OPTIONS:
- endocrinologists
- vaccinologists
- virologists
- immunologists
Answer: immunologists

input with options: Answer the following question given this paragraph: An amino acid is a compound that contains both an amino group (NH 2 ) and a carboxyl group (COOH) in the same molecule. While any number of amino acids can possibly be imagined, biochemists generally reserve the term for a group of 20 amino acids which are formed and used by living organisms. The Figure below shows the general structure of an amino acid. Q: What do you call a compound that contains both an amino group and a carboxyl group in the same molecule? A:
OPTIONS:
- carbolic acid
- compound acid
- catalyst
- amino acid
output: amino acid

Question: Answer the following question given this paragraph: When fossil fuels burn, they release thermal energy, water vapor, and carbon dioxide. Carbon dioxide produced by fossil fuel use is a major cause of global warming. The burning of fossil fuels also releases many pollutants into the air. Pollutants such as sulfur dioxide form acid rain, which kills living things and damages metals, stonework, and other materials. Pollutants such as nitrogen oxides cause smog, which is harmful to human health. Tiny particles, or particulates, released when fossil fuels burn also harm human health. Natural gas releases the least pollution; coal releases the most (see Figure below ). Petroleum has the additional risk of oil spills, which may seriously damage ecosystems. Q: What gas produced by fossil fuel use is a major cause of global warming? A:
OPTIONS:
- helium
- hydrogen
- phosphorous
- carbon dioxide
Answer:
carbon dioxide
