Answer the following question given this paragraph: Like microscopes, telescopes use convex lenses to make enlarged images. However, telescopes make enlarged images of objectssuch as distant starsthat only appear tiny because they are very far away. There are two basic types of telescopes: reflecting telescopes and refracting telescopes. The two types are compared in the Figure below . They differ in how they collect light, but both use convex lenses to form enlarged images. You can learn more about telescopes and how they evolved in the video at this URL:. Q: Telescopes use which kind of lenses to enlarge images? Choices: - crystalline - spherical - concave - convex A:
convex
Answer the following question given this paragraph: The amount of charge, , held by each plate is given by where again is the voltage difference between the plates and is the capacitance of the plate configuration. Capacitance can be thought of as the capacity a device has for storing charge . In the parallel plate case the capacitance is given by where is the area of the plates, is the distance between the plates, and is the permittivity of free space whose value is . Q: What can be thought of as the capacity a device has for storing charge? Choices: - potential - velocity - resonance - capacitance A:
capacitance
Q: Answer the following question given this paragraph: Q: Stomata are the main avenues of transpiration, the evaporative loss of water from what? Choices: - fruits - roots - stalks - leaves A:
A: leaves
Question: Answer the following question given this paragraph: A common way to keep track of valence electrons is with Lewis electron dot structures . In an electron dot structure, each atom is represented by its chemical symbol, and each valence electron is represented by a single dot. Note that only valence electrons are shown explicitly in these diagrams. For the main group elements, the number of valence electrons for a neutral atom can be determined by looking at which group the element belongs to. In the s block, Group 1 elements have one valence electron, while Group 2 elements have two valence electrons. In the p block, the number of valence electrons is equal to the group number minus ten. Group 13 elements have three valence electrons, Group 14 elements have four, and so on. The noble gases in Group 18 have eight valence electrons, and the full outer s and p sublevels are what give these elements their special stability. Representative dot diagrams are shown in the Figure below :. Q: The group 18 gases that have 8 valence electrons are referred to as what type of gases? Choices: - novel - important - metal - noble A:
Answer: noble

Answer the following question given this paragraph: Tuberculosis (TB) is a common and often deadly disease caused by a genus of bacterium called Mycobacterium . Tuberculosis most commonly attacks the lungs but can also affect other parts of the body. TB is a chronic disease, but most people who become infected do not develop the full disease. Symptoms include a cough, which usually contains mucus and coughing up blood. Q: What type of bacteria causes the disease called tuberculosis? Choices: - E. coli - staphylococcus - streptococcus - mycobacterium A:
**Answer**
mycobacterium

Answer the following question given this paragraph: At a geothermal power plant, engineers drill wells into the hot rocks. Hot water or steam may come up through the wells. Alternatively, water may be put down into the well to be heated. It then comes up. The hot water or steam makes a turbine spin. This makes electricity. Pictured below is an example of a geothermal power plant ( Figure below ). Q: Drilling wells into hot rocks to release hot water or steam is an example of what kind of power plant? Choices: - hydroelectric - solar - fossil fuel - geothermal A:
**Answer**
geothermal
