Answer the following question given this paragraph: Zeros that show only where the decimal point falls are not significant. For example, the number 470,000 has just two significant figures (4 and 7). The zeros just show that the 4 represents hundreds of thousands and the 7 represents tens of thousands. Therefore, these zeros are not significant. Q: Are zeroes that show only where the decimal point fall significant or not significant? Choices: - neither - sometimes significant - significant - not significant A:
not significant
Answer the following question given this paragraph: Stars shine because of nuclear fusion. Fusion reactions in the Sun's core keep our nearest star burning. Stars are made mostly of hydrogen and helium. Both are very lightweight gases. A star contains so much hydrogen and helium that the weight of these gases is enormous. The pressure at the center of a star is great enough to heat the gases. This causes nuclear fusion reactions. Q: What process, which results because of great pressure at the center of a star, causes stars to shine? Choices: - gravitational pull - electric fusion - energy fusion - nuclear fusion A:
nuclear fusion
Q: Answer the following question given this paragraph: If a solution contains so much solute that its solubility limit is reached, the solution is said to be saturated, and its concentration is known from information contained inTable 9.2 "Solubilities of Various Solutes in Water at 25C (Except as Noted)". If a solution contains less solute than the solubility limit, it is unsaturated. Under special circumstances, more solute can be dissolved even after the normal solubility limit is reached; such solutions are called supersaturated and are not stable. If the solute is solid, excess solute can easily recrystallize. If the solute is a gas, it can bubble out of solution uncontrollably, like what happens when you shake a soda can and then immediately open it. Q: If a solution contains so much solute that its solubility limit is reached, the solution is said to be what? Choices: - carbohydrates - Over done - temperatures - saturated A:
A: saturated
Question: Answer the following question given this paragraph: Brain injuries can range from mild to extremely severe, but even mild injuries need medical attention. Brain injuries can result from falls, car accidents, violence, sports injuries, and war and combat. Falls are the most common cause of brain injuries, particularly in older adults and young children. Q: What are the most common causes of brain injuries? Choices: - excessive shaking - lightning strikes - alcohol poisoning - falls A:
Answer: falls

Answer the following question given this paragraph: The cell is the basic unit of structure and function of all organisms. The Cell Theory states that all living things are made of one or more cells, or the secretions of those cells, such as the organisms shown in Figure below . For example, shell and bone are built by cells from substances that they secrete into their surroundings. Cells come from cells that already exist, that is, they do not suddenly appear from nowhere. In organisms that are made of many cells (called multicellular organisms), every cell in the organism's body derives from the single cell that results from a fertilized egg. You will learn more about cells and the Cell Theory in Cells: The Cell Theory (Advanced) concept. Q: What is the basic unit of structure and function in all organisms? Choices: - the atom - the neutron - the electron - the cell A:
**Answer**
the cell
