Question: Q: This inverse relationship between solubility and temperature can be understood by looking at a what? Read this paragraph and choose the correct option from the provided answers: This inverse relationship between solubility and temperature can be understood by looking at a molecular model. Recall that higher temperatures are associated with faster particles. Gas particles are held in solution by attractive interactions with the solvent molecules. If the particles are moving slowly, these attractive forces will pull back any particles that try to escape the surface of the solution and re-enter the gas phase. However, if the gas particles are moving fast enough, these interactions will not be sufficiently strong to prevent this process from occurring. As a result, more particles are able to escape, and the amount of dissolved solute is less than it would be at a lower temperature. Choices: - nutrient model - a slide - potassium model - molecular model A:
Answer: molecular model

Question: Q: Carboxylic acids are weak acids, meaning they are not 100% ionized in what? Read this paragraph and choose the correct option from the provided answers: Carboxylic acids are weak acids (see the chapter on acids and bases), meaning they are not 100% ionized in water. Generally only about 1% of the molecules of a carboxylic acid dissolved in water are ionized at any given time. The remaining molecules are undissociated in solution. We prepare carboxylic acids by the oxidation of aldehydes or alcohols whose OH functional group is located on the carbon atom at the end of the chain of carbon atoms in the alcohol:. Choices: - air - ethanol - liquid - water A:
Answer: water

Question: Q: What is the transfer of information from rna to dna called? Read this paragraph and choose the correct option from the provided answers: Reverse transcription is the transfer of information from RNA to DNA. The is the reverse of normal transcription. Reverse transcription occurs in retroviruses, such as HIV, the virus that causes AIDS. Retroviruses are RNA viruses that are duplicated in a host cell by using reverse transcriptase enzyme to produce DNA from its RNA genome. Choices: - confront transcription - forward transcription - reverse differentiation - reverse transcription A:
Answer:
reverse transcription
