Answer the following question given this paragraph: The photosphere is the visible surface of the Sun ( Figure below ). It's the part that we see shining. Surprisingly, the photosphere is also one of the coolest layers of the Sun. It is only about 6000 degrees C. Q: The visible surface of the sun is called what? Choices: - Corona - Radiative Zone - Chromosphere - photosphere A:
photosphere
Answer the following question given this paragraph: The nucleus is an example of an organelle . An organelle is any structure inside a cell that is enclosed by a membrane. Eukaryotic cells may contain many different organelles. Each does a special job. For example, the mitochondrion is an organelle that provides energy to the cell. You can see a mitochondrion and several other organelles in the animal cell in Figure above . Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Q: Any structure inside a cell that is enclosed by a membrane is called? Choices: - an article - a particle - an enclave - an organelle A:
an organelle
Q: Answer the following question given this paragraph: At a convergent plate boundary, when one plate is oceanic, there are large volcanoes. These volcanoes are found in lines that outline the subduction zone. Earthquakes also happen in these zones. The Aleutian Islands that border southern Alaska are an island arc. In this winter image from space, the volcanoes are covered with snow. Q: At a convergent plate boundary, when one plate is oceanic, there are large what? Choices: - plateaus - lakes - earthquakes - volcanoes A:
A: volcanoes
Question: 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? Choices: - radiactive - inactive - proactive - reactive A:
Answer: reactive

Answer the following question given this paragraph: Q: Membranes will become increasingly what as temperatures rise? Choices: - acidic - metallic - toxic - fluid A:
**Answer**
fluid
Q: Answer the following question given this paragraph: Photosynthesis changes light energy to chemical energy. The chemical energy is stored in the bonds of glucose molecules. Glucose is used for energy by the cells of almost all living things. Plants make their own glucose. Other organisms get glucose by consuming plants (or organisms that consume plants). How do living things get energy from glucose? The answer is cellular respiration. Q: Photosynthesis changes light energy to what type of energy? Choices: - radiation - potential - solar - chemical A:
A: chemical
