Question: Answer the following question given this paragraph:   Organisms that live in a hypotonic environment such as freshwater, need a way to prevent their cells from taking in too much water by osmosis. A contractile vacuole is a type of vacuole that removes excess water from a cell. Freshwater protists, such as the paramecia shown in Figure below , have a contractile vacuole. The vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole. When the vacuole is full, it pushes the water out of the cell through a pore. Other protists, such as members of the genus Amoeba , have contractile vacuoles that move to the surface of the cell when full and release the water into the environment.   Q: Organisms that live in freshwater environments often possess a contractile vacuole that prevents cells from taking in too much water through what process?   A:
OPTIONS:
- electrolysis
- glycolysis
- hemostasis
- osmosis
Answer: osmosis

Answer the following question given this paragraph:   Pure elements with a high metallic character, meaning those that have chemical properties most similar to properties of metals, are generally very reactive. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have a relatively low attraction to shared electrons, as indicated by their low electronegativity values. By following the trend summary in Figure below , you can see that the most reactive metals would reside in the lower left portion of the periodic table. The most reactive metal that occurs naturally in reasonable quantities is cesium, which is always found in nature as a compound, never as a free element. It reacts explosively with water and will ignite spontaneously in air. Francium is below cesium in the alkali metal group, but it is so rare that many of its properties have never even been observed.   Q: Exemplified by cesium, which ignites spontaneously in air, pure elements with a high metallic character tend to be very what?   A:

OPTIONS:
- radiactive
- inactive
- proactive
- reactive

Answer: reactive

Q: Answer the following question given this paragraph:   The explosion of nitroglycerin releases large volumes of gases and is very exothermic.   Q: The explosion of nitroglycerin, which releases large volumes of gases, is what type of reaction?   A:

OPTIONS:
- energetic
- exponential
- endothermic
- exothermic

A:
exothermic
