Answer the following question given this paragraph: Q: Under which conditions do many bacteria carry out alcohol fermentation? Choices: - melting - enzymatic - photosynthesis - anaerobic A:
anaerobic
Answer the following question given this paragraph: A laboratory instrument used to analyze and test for static charge is called an electroscope. Seen below, an electroscope consists of a metal knob connected by a metal stem to two very lightweight pieces of metal called leaves, shown in yellow. The leaves are enclosed in a box to eliminate stray air currents. Q: What laboratory instrument is used to analyze and test for static charge? Choices: - microscope - bunsen burner - microtome - electroscope A:
electroscope
Q: Answer the following question given this paragraph: Carbon dioxide emissions into the atmosphere from fossil fuel burning have been rising for the past several decades. Q: Emissions of what gas into the atmosphere from fossil fuel burning have been rising for the past several decades? Choices: - sulphur - oxygen - neon - carbon dioxide A:
A: carbon dioxide
Question: Answer the following question given this paragraph: Large stars burn through their supply of hydrogen very quickly. These stars "live fast and die young!" A very large star may only be on the main sequence for 10 million years. A very small star could remain on the main sequence for tens to hundreds of billions of yearsfar longer than the current age of our Universe. Q: How long can a large star be on the main sequence stage? Choices: - 3 million years - 200.4 million years - 60.11 million years - 10 million years A:
Answer: 10 million years

Answer the following question given this paragraph: Tight junctions are composed of strands of transmembrane proteins embedded in the plasma membranes of two adjacent cells. The extracellular domains of these proteins directly join to one another. These joining proteins associate with peripheral membrane proteins located on the intracellular side of plasma membrane. These peripheral proteins anchor the strands to the actin component of the cytoskeleton, effectively forming a molecular complex that joins together the cytoskeletons of adjacent cells. The major types anchoring proteins of tight junctions are the claudins and the occludins. Q: What are the major types anchoring proteins? Choices: - semimetals and occludins - amino and fatty acids - claudins and semimetals - claudins and occludins A:
**Answer**
claudins and occludins
Q: Answer the following question given this paragraph: The molar mass of any substance is the mass in grams of one mole of representative particles of that substance. The representative particles can be atoms, molecules, or formula units of ionic compounds. This relationship is frequently used in the laboratory. Suppose that for a certain experiment you need 3.00 moles of calcium chloride (CaCl 2 ). Since calcium chloride is a solid, it would be convenient to use a balance to measure the mass that is needed. The molar mass of CaCl 2 is 110.98 g/mol. The conversion factor that can be used is then based on the equality that 1 mol = 110.98 g CaCl 2 . Dimensional analysis will allow you to calculate the mass of CaCl 2 that you should measure. Q: Who first proposed that earth is a magnet? Choices: - Albert Einstein - Isaac Newton - Marconi - william gilbert A:
A: william gilbert
