- isotope
- neutrino
- an ion

Answer the following question given this paragraph: Atoms cannot only gain extra electrons. They can also lose electrons. In either case, they become ions . Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons. If atoms lose electrons, they become positive ions, or cations. If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below ). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1. Q: What's the name for an atom that has gained or lost an electron? A:
****
A: an ion

Answer the following question given this paragraph: on a daily basis as a preventive measure. However, aspirin can also lead to serious side effects, including increasing the risk of ulcers. A patient is well advised to consult a physician before beginning any aspirin regimen. A class of drugs collectively known as thrombolytic agents can help speed up the degradation of an abnormal clot. If a thrombolytic agent is administered to a patient within 3 hours following a thrombotic stroke, the patient's prognosis improves significantly. However, some strokes are not caused by thrombi, but by hemorrhage. Thus, the cause must be determined before treatment begins. Tissue plasminogen activator is an enzyme that catalyzes the conversion of plasminogen to plasmin, the primary enzyme that breaks down clots. It is released naturally by endothelial cells but is also used in clinical medicine. New research is progressing using compounds isolated from the venom of some species of snakes, particularly vipers and cobras, which may eventually have therapeutic value as thrombolytic agents. Q: Snake venom may join the class of drugs collectively known as thrombolytic agents, which can help speed up the degradation of an abnormal what? A:
OPTIONS:
- brain
- bleed
- bone
- clot
clot

Answer the following question given this paragraph: Complex Tissue Structure A hallmark trait of animals is specialized structures that are differentiated to perform unique functions. As multicellular organisms, most animals develop specialized cells that group together into tissues with specialized functions. A tissue is a collection of similar cells that had a common embryonic origin. There are four main types of animal tissues: nervous, muscle, connective, and epithelial. Nervous tissue contains neurons, or nerve cells, which transmit nerve impulses. Muscle tissue contracts to cause all types of body movement from locomotion of the organism to movements within the body itself. Animals also have specialized connective tissues that provide many functions, including transport and structural support. Examples of connective tissues include blood and bone. Connective tissue is comprised of cells separated by extracellular material made of organic and inorganic materials, such as the protein and mineral deposits of bone. Epithelial tissue covers the internal and external surfaces of organs inside the animal body and the external surface of the body of the organism. Q: What term describes a collection of similar cells that had a common embryonic origin? A:
OPTIONS:
- organ-level organization
- plasma
- nucleus
- tissue

Answer: tissue

input with options: Answer the following question given this paragraph: Figure 34.16 Digestion of carbohydrates is performed by several enzymes. Starch and glycogen are broken down into glucose by amylase and maltase. Sucrose (table sugar) and lactose (milk sugar) are broken down by sucrase and lactase, respectively. Q: Digestion of carbohydrates is performed by several enzymes. starch and glycogen are broken down into glucose by amylase and maltase. sucrose (table sugar) and lactose (milk sugar) are broken down by sucrase and this? A:
OPTIONS:
- lipase
- pepsin
- hydrolase
- lactase
output: lactase

Problem: OPTIONS:
- silt
- subsurface
- topsoil
- subsoil
Q: Answer the following question given this paragraph: Below the topsoil is the "B" horizon. This is also called the subsoil . Soluble minerals and clays accumulate in the subsoil. Because it has less organic material, this layer is lighter brown in color than topsoil. It also holds more water due to the presence of iron and clay. There is less organic material in this layer. Q: Soluble minerals and clays accumulate in what soil layer, allowing it to hold more water? A:
Answer:
subsoil
