Q: Q: Compounds containing an atom of what element, bonded in a hydrocarbon framework, are classified as amines? Read this paragraph and choose the correct option from the provided answers: 20.2 Alcohols and Ethers Many organic compounds that are not hydrocarbons can be thought of as derivatives of hydrocarbons. A hydrocarbon derivative can be formed by replacing one or more hydrogen atoms of a hydrocarbon by a functional group, which contains at least one atom of an element other than carbon or hydrogen. The properties of hydrocarbon derivatives are determined largely by the functional group. The OH group is the functional group of an alcohol. The ROR group is the functional group of an ether. 20.3 Aldehydes, Ketones, Carboxylic Acids, and Esters Functional groups related to the carbonyl group include the CHO group of an aldehyde, the CO group of a ketone, the CO2H group of a carboxylic acid, and the CO2R group of an ester. The carbonyl group, a carbon-oxygen double bond, is the key structure in these classes of organic molecules: Aldehydes contain at least one hydrogen atom attached to the carbonyl carbon atom, ketones contain two carbon groups attached to the carbonyl carbon atom, carboxylic acids contain a hydroxyl group attached to the carbonyl carbon atom, and esters contain an oxygen atom attached to another carbon group connected to the carbonyl carbon atom. All of these compounds contain oxidized carbon atoms relative to the carbon atom of an alcohol group. 20.4 Amines and Amides The addition of nitrogen into an organic framework leads to two families of molecules. Compounds containing a nitrogen atom bonded in a hydrocarbon framework are classified as amines. Compounds that have a nitrogen atom bonded to one side of a carbonyl group are classified as amides. Amines are a basic functional group. Amines and carboxylic acids can combine in a condensation reaction to form amides. Choices: - oxygen - hydrogen - ammonia - nitrogen A:
A: nitrogen

Q: Q: What is the name of the cell that results when a sperm nucleus fuses with a egg nucleus? Read this paragraph and choose the correct option from the provided answers: When a sperm penetrates the egg, it triggers the egg to complete meiosis. The sperm also undergoes changes. Its tail falls off, and its nucleus fuses with the nucleus of the egg. The resulting cell, called a zygote , contains all the chromosomes needed for a new human organism. Half the chromosomes come from the egg and half from the sperm. Choices: - t cell - a cytoplasm - a filament - a zygote A:
A: a zygote

Q: Q: What is the name of vesicles that are formed by the golgi apparatus? Read this paragraph and choose the correct option from the provided answers: Lysosomes are vesicles that are formed by the Golgi apparatus. They contain powerful enzymes that could break down (digest) the cell. Lysosomes break down harmful cell products, waste materials, and cellular debris and then force them out of the cell. They also digest invading organisms such as bacteria. Lysosomes also break down cells that are ready to die, a process called autolysis. Choices: - vessels - lymphocytes - capillaries - lysosomes A:
A: lysosomes

Q: Q: Liquids with strong intermolecular forces have higher what than liquids with weaker forces? Read this paragraph and choose the correct option from the provided answers: Liquids with strong intermolecular forces have higher surface tensions than liquids with weaker forces. Choices: - temperature - melting point - freezing point - surface tension A:
A: surface tension
