Correct Answer: B) at zero price, quantity supplied exceeds quantity demanded

Explanation

This question is asking about a free good and which situation represents a free good. A free good is a good that is available in abundance and has no opportunity cost. In other words, it is a good that can be obtained without paying a price.

Option A states that when more is demanded than supplied at zero price, we have a free good. This is incorrect because if there is more demand than supply, it means the good is scarce and not freely available.

Option C states that at equilibrium price, quantity supply is equal to quantity demanded. This does not represent a free good because there is still a price attached to it.

Option D states that any quantity can be obtained when the price is low. This does not represent a free good because there is still a price attached to it.

Option B states that at zero price, quantity supplied exceeds quantity demanded. This represents a free good because it is available in abundance and there is no price attached to it. Examples of free goods include air, sunlight, and water from natural sources.

In summary, the correct answer is Option B, which represents a free good. To learn more about this, please read the relevant sections of the recommended textbooks.

Correct Answer: B) Xylem

Explanation

Vascular tissues play an essential role in the transportation of water and minerals in plants. They are responsible for the structural support of plants as they provide a system of tubes that help in the distribution of nutrients throughout the plant. The question is asking to identify an example of vascular tissue. The correct answer to this question is Option B: Xylem. Xylem is a type of vascular tissue that carries water and minerals from the roots to the stems and leaves of plants. It is made up of hollow, tube-like structures called vessels, which are connected end-to-end to form long continuous tubes. These tubes are strengthened by lignin, a complex polymer that provides structural support to the plant. It is important to note that while all vascular tissues serve a similar function, there are two types of vascular tissues in plants: xylem and phloem. Xylem carries water and minerals from the roots to the rest of the plant, while phloem transports organic compounds such as sugars from the leaves to the rest of the plant. To summarize, the correct answer to this question is Option B: Xylem, which is an example of vascular tissue responsible for the transportation of water and minerals in plants.
