Correct Answer: C. appendicular skeleton

Correct Answer: C. previous year's sales volume

Correct Answer: D. Gopher wood

Correct Answer: A) Ethyne

Explanation

Ethyne (C₂H₂) is the correct answer because it will undergo addition reactions, while the other options will not. Ethyne is an alkyne, which is a hydrocarbon containing a carbon-carbon triple bond. Alkynes can participate in addition reactions due to the presence of the triple bond, which can break and form new bonds with other atoms or molecules.

Butane (C₄H₁₀) and Pentane (C₅H₁₂) are both alkanes, a type of hydrocarbon with only single bonds between carbon atoms. Alkanes generally do not undergo addition reactions because they have no reactive sites, like double or triple bonds, in their structure.

Ethanol (C₂H₅OH) is an alcohol, which means it contains an -OH group. Alcohols are less likely to undergo addition reactions because the hydroxyl group is not as reactive as the carbon-carbon double or triple bonds found in alkenes or alkynes.

Tetrachloromethane (CCl₄) is a compound with a carbon atom surrounded by four chlorine atoms. It does not have any reactive sites, like double or triple bonds, which would allow it to undergo addition reactions.

In summary, ethyne is the compound that will undergo addition reactions, due to the presence of a carbon-carbon triple bond, while the other compounds do not have the necessary reactive sites to participate in these types of reactions.

Correct Answer: B. the Ark of God was captured

Correct Answer: B. materiality

Correct Answer: C. marginal utility deceases as consumption increase

Explanation

diminishing marginal utility explains that as a person consumes an item or a product, the satisfaction or utility that they derive from the product reduces as they consume more and more of that product. This means that the satisfaction that is meant to be derived from consuming an additional unit of a commodity reduces as you consume more of that commodity.

Correct Answer: D) water molecules from a dilute solution to a concentrated solution through a semi permeable membrane

Explanation

Osmosis refers to the movement of water molecules from a region of high concentration to a region of low concentration across a semi-permeable membrane. This process is passive and does not require energy. The question is asking us to identify the correct definition of osmosis from the given options. Option A is incorrect because osmosis is specifically the diffusion of water molecules, not atoms and molecules in general. Option B is correct because it describes the movement of water molecules from a dilute solution to a concentrated solution across a semi-permeable membrane. Option C is incorrect because it describes the process of diffusion, not osmosis. Option E is also incorrect because it does not relate to the movement of water molecules across a semi-permeable membrane. Therefore, the correct answer to this question is Option D, which correctly describes the movement of water molecules from a dilute solution to a concentrated solution through a semi-permeable membrane.
