Answer the following question given this paragraph: Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is. Q: Intensity is defined to be the power per unit area carried by a what? A:
****
A: wave

Answer the following question given this paragraph: Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the hydrogen atoms in Figure above . Alone, each hydrogen atom has just one electron. By sharing electrons with another hydrogen atom, it has two electrons: its own and the one in the other hydrogen atom. The shared electrons are attracted to both hydrogen nuclei. This force of attraction holds the two atoms together as a molecule of hydrogen. Q: What bonds form because they give atoms a more stable arrangement of electrons? A:
OPTIONS:
- Hydrogen bond
- Ionic bond
- Polar bond
- covalent
covalent

Answer the following question given this paragraph: Edema may be accompanied by varicose veins, especially in the superficial veins of the legs (Figure 20.8). This disorder arises when defective valves allow blood to accumulate within the veins, causing them to distend, twist, and become visible on the surface of the integument. Varicose veins may occur in both sexes, but are more common in women and are often related to pregnancy. More than simple cosmetic blemishes, varicose veins are often painful and sometimes itchy or throbbing. Without treatment, they tend to grow worse over time. The use of support hose, as well as elevating the feet and legs whenever possible, may be helpful in alleviating this condition. Laser surgery and interventional radiologic procedures can reduce the size and severity of varicose veins. Severe cases may require conventional surgery to remove the damaged vessels. As there are typically redundant circulation patterns, that is,. Q: Wich disorder arises when defective valves allow blood to accumulate within the veins? A:
OPTIONS:
- vascular disease
- bulging veins
- cataracts veins
- varicose veins

Answer: varicose veins

Question: Answer the following question given this paragraph: Vegetable oils are being explored for a variety of uses in which they could replace petroleum products. One such application is in the field of lubricants. Every moving part in machinery (such as engine pistons) needs lubrication to decrease friction and prolong the life of the equipment. Petroleum products serve this purpose now, but are not good for the environment. New techniques for making specialized esters from vegetable oil are being explored that will make the compounds more stable and more useful as lubricants. Q: What type of oil is being explored to replace petroleum products in lubricants? A:
OPTIONS:
- essential oil
- diesel
- whale oil
- vegetable
Answer: vegetable

input with options: Answer the following question given this paragraph: Temperature falls from the equator to the poles. Therefore, major temperature zones are based on latitude. They include tropical, temperate, and arctic zones (see Figure below ). However, other factors besides latitude may also influence temperature. For example, land near the ocean may have cooler summers and warmer winters than land farther inland. This is because water gains and loses heat more slowly than does land, and the water temperature influences the temperature on the coast. Temperature also falls from lower to higher altitudes. That's why tropical zone mountain tops may be capped with snow. Q: Water gains and loses what more slowly than does land, affecting seasonal conditions inland and on the coast? A:
OPTIONS:
- volume
- humidity
- minerals
- heat
output: heat

Problem: OPTIONS:
- cities
- tribes
- nobles
- kingdoms
Q: Answer the following question given this paragraph: The level of biodiversity found in the fossil record suggests that the last few million years include the period of greatest biodiversity in the Earth's history. However, not all scientists support this view, since there is a lot of uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of more recent fossil-containing rock layers. Some researchers argue that modern biodiversity is not much different from biodiversity 300 million years ago. Estimates of the present global species diversity vary from 5 million to 30 million species, with a best estimate of somewhere near 10 million species. All living organisms are classified into one of the six kingdoms: Archaebacteria (Archaea), Eubacteria (Bacteria), Protista (Protists), Fungi, Plantae (Plants), and Animalia (Animals). Q: All living organisms are classified into one of six broad categories called what? A:
Answer:
kingdoms
