Correct Answer: A. avoided the real issue

Correct Answer: C. sacrifice made for the satisfaction of a want

Correct Answer: D) ii, iv, and v

Explanation

This Biology question is asking which structures are found in both animal cells and plant cells. The structures listed in the question are cell wall, cell membrane, chloroplast, cytoplasm, nucleus, and sap vacuole. We are to identify which of these structures are present in both animal and plant cells. Animal cells and plant cells have some similarities and differences in their structures. Both animal cells and plant cells have a cell membrane, which is a thin and flexible layer that surrounds the cell. The cell membrane controls the movement of substances in and out of the cell. Both animal cells and plant cells also have a nucleus, which is the control center of the cell that contains the genetic material of the cell. However, there are some structures that are present in plant cells but not in animal cells. For example, plant cells have a cell wall, which is a rigid layer that provides support and protection to the cell. Plant cells also have chloroplasts, which are organelles that carry out photosynthesis, the process by which plants make their own food. Based on the structures listed in the question, the structures that are found in both animal cells and plant cells are the cell membrane, nucleus, and cytoplasm. The correct answer is Option D, which includes these three structures. The other options include structures that are only found in either plant cells or animal cells. In summary, both animal cells and plant cells have a cell membrane, nucleus, and cytoplasm. Plant cells have additional structures such as a cell wall and chloroplasts that are not present in animal cells.

Correct Answer: D) former does not require any of the country to have absolute advantage in any of the two goods but latter require that one of the countries should have absolute advantage in at least one of the goods

Explanation

This Economics question is asking about the differences between the law of comparative cost and absolute cost advantage. The options provide different statements about these differences, and we are to choose the correct option.

Option A says that the former requires that one of the countries has absolute advantage in both goods, while the latter does not. This is incorrect because the law of comparative cost does not require that one country has absolute advantage in both goods.

Option B says that the former requires one country to have at least absolute advantage in one of the trading goods over the other country, while the latter does not. This is also incorrect because the law of comparative cost does not require absolute advantage in any of the goods.

Option C says that the former does not require any of the country to have absolute advantage in any of the two goods, but the latter requires that one of the countries should have absolute advantage in all the goods. This is incorrect because the law of absolute cost advantage does not require absolute advantage in all the goods.

Option D is the correct answer. It says that the former does not require any of the country to have absolute advantage in any of the two goods, but the latter requires that one of the countries should have absolute advantage in at least one of the goods. This means that while the law of comparative cost does not require absolute advantage, the law of absolute cost advantage requires at least one country to have absolute advantage in one of the goods.

In summary, the key difference between the law of comparative cost and absolute cost advantage is that the former does not require absolute advantage in any of the goods, while the latter requires at least one country to have absolute advantage in one of the goods.

Correct Answer: A. constant high temperature

Explanation

(a) \(y = k + \frac{c}{x^{2}}\)

where c and k are constants.

(b) When x = 1, y = 11

\(11 = k + \frac{c}{1^{2}} \implies 11 = k + c ... (1)\)

When x = 2, y = 5

\(5 = k + \frac{c}{2^{2}} \implies 5 = k + \frac{c}{4}\)

\(\equiv 20 = 4k + c ... (2)\)

(2) - (1) :

\(4k - k = 20 - 11 \implies 3k = 9\)

\(k = 3\)

Put k = 3 in (1), we have

\(11 = 3 + c \implies c = 11 - 3 = 8\)

\(\therefore y = 3 + \frac{8}{x^{2}}\)

When x = 4,

\(y = 3 + \frac{8}{4^{2}} = 3 + \frac{1}{2}\)

= \(3\frac{1}{2}\)
