Ques: Answer the following question given this paragraph: An ether is an organic compound in which two hydrocarbon groups are bonded to the same atom of oxygen. An ether is represented by the general formula ROR'. The R' in the formula means that the hydrocarbon group can be the same as R or it can be different. The steps for naming ethers are listed below. Q: An ether is an organic compound in which two hydrocarbon groups are bonded to the same atom of what? Choices: - hydrogen - sulfur - nitrogen - oxygen A:
Ans: oxygen

Answer the following question given this paragraph: Sound intensity levels are quoted in decibels (dB) much more often than sound intensities in watts per meter squared. Decibels are the unit of choice in the scientific literature as well as in the popular media. The reasons for this choice of units are related to how we perceive sounds. How our ears perceive sound can be more accurately described by the logarithm of the intensity rather than directly to the intensity. The sound intensity level in decibels of a sound having an intensity I in watts per meter squared is defined to be. Q: What is the measure of sound intensity levels? Choices: - octaves - moles - centimeters - decibels A:
(A).
decibels
Ques:Answer the following question given this paragraph: Recall that eukaryotic organisms also include animals, protists, and fungi. Eukaryotes have cells with nuclei that contain DNA, and membrane-bound organelles, such as mitochondria. Photosynthesis is the process by which plants capture the energy of sunlight and use carbon dioxide from the air (and water) to make their own food, the carbohydrate glucose. Plants have chloroplasts, the organelle of photosynthesis, and are known as producers and autotrophs. Other organisms are heterotrophic consumers, meaning they must obtain their nutrients from another organism, as these organisms lack chloroplasts. Lastly, plants must be multicellular, composed of more than one cell. There are no single-celled plants. Recall that some protists, such as algae, are eukaryotic and photosynthetic but are not considered plants. Unlike plants, algae is mostly unicellular. Q: What is the process by which plants capture the energy of sunlight and use carbon dioxide from the air (and water) to make their own food called? Choices: - spermatogenesis - photochemistry - atherosclerosis - photosynthesis A:

Ans:photosynthesis
Ques: Answer the following question given this paragraph: Figure 12.7 Statues made from carbonate compounds such as limestone and marble typically weather slowly over time due to the actions of water, and thermal expansion and contraction. However, pollutants like sulfur dioxide can accelerate weathering. As the concentration of air pollutants increases, deterioration of limestone occurs more rapidly. (credit: James P Fisher III). Q: Deterioration of limestone occurs more rapidly as the concentration of what increases? Choices: - ground pollutants - water pollutants - ocean pollutants - air pollutants A:
Ans:
air pollutants
