Correct Answer: B. wiped out

Correct Answer: A. re-afforestation and planting of tress on wind break

Correct Answer: B. gets discount if he pays within 3 months

Correct Answer: D) 8.3 cm³

Explanation

Using dilution factor \(C_1V_1 = C_2V_2\)

Where \(C_1\) is concentration 1 in mol per dm\(^3\)

\(C_2\) is concentration 2 in mol per dm\(^3\)

\(V_1\) is volume 1

\(V_2\) is volume 2

Therefore it can be deduced as

\(0.750 \times V_1 = 250 \times 0.025\)

\(V_1 = \cfrac{6.25}{0.75}\)

\(V_1 = 8.333\) cm\(^3\)

Correct Answer: D) Nigeria

Explanation

The legislative council was a form of government in British West Africa where people were elected to represent their community and make laws. Before Africans were allowed to participate in the council, it was made up of only British officials.

Nigeria was the first country in British West Africa to have Africans elected to the legislative council. This happened in 1946, when three Nigerians were elected. This was an important moment in Nigeria's history, as it marked the beginning of a movement towards independence from British rule.

Sierra Leone, The Gambia, and Ghana also eventually had Africans elected to their legislative councils, but Nigeria was the first. It's important to know about the history of government and politics in Africa, as it has a big impact on the continent's present and future.

Correct Answer: D) cell membrane

Explanation

This question is asking for a similarity between a typical animal cell and a typical plant cell. The options are cellulose, chlorophyll, centrally placed nucleus, cell membrane, and large vacuole. Both animal and plant cells are two types of eukaryotic cells, which means they have a nucleus and other membrane-bound organelles. In terms of similarities, both types of cells have a cell membrane which is responsible for controlling what goes in and out of the cell, and for providing structure and support to the cell. Option A, cellulose, is a carbohydrate that is found in the cell walls of plant cells but not in animal cells. Option B, chlorophyll, is a pigment that is found in plant cells but not in animal cells. Chlorophyll is responsible for absorbing light energy for photosynthesis. Option C, centrally placed nucleus, is not a similarity between the two cells because in animal cells, the nucleus is not always centrally placed while in plant cells, the nucleus is usually located at the periphery of the cell. Option E, large vacuole, is a characteristic of plant cells but not typical animal cells. Therefore, the correct answer is option D, cell membrane, which is a similarity between typical animal and plant cells as both types of cells have cell membranes. It is important to note that while there are similarities between animal and plant cells, there are also many differences. For example, plant cells have chloroplasts and a large central vacuole, while animal cells do not. Overall, understanding the similarities and differences between animal and plant cells is important for understanding basic cell biology and the functions of different organelles within the cell.
