Correct Answer: C) Mitochondria

Explanation

In a cell, energy is produced in a specific organelle called the mitochondria. The mitochondria are often referred to as the powerhouse of the cell because they are responsible for producing ATP, which is the primary source of energy for the cell. ATP is produced through a process called cellular respiration, which occurs in the mitochondria. The process of cellular respiration involves breaking down glucose and other molecules to release energy, which is then used to produce ATP. The other options listed in the question, such as the nucleus, lysosomes, and nucleolus, do not play a role in energy production. The nucleus contains genetic material and is responsible for controlling cellular activities, while lysosomes are involved in breaking down waste and foreign substances. The nucleolus is involved in the production of ribosomes, which are responsible for synthesizing proteins. It is important to understand the functions of different organelles within the cell, as they all play important roles in maintaining cellular function. For example, the endoplasmic reticulum is responsible for protein synthesis and lipid metabolism, while the Golgi apparatus is involved in the processing and packaging of proteins for secretion. In summary, the correct answer to the question is option C: Mitochondria. To better understand the functions of various organelles within the cell, it is important to study cellular biology in more detail.

Correct Answer: B. weather

Correct Answer: B) Bromine water

Explanation

Butene and benzene are two different types of hydrocarbons. Butene is an alkene, which contains a carbon-carbon double bond, while benzene is an aromatic compound with a ring structure and alternating single and double bonds.

Alkenes, like butene, undergo addition reactions due to the presence of the carbon-carbon double bond. One such reaction is with bromine water. When bromine water is added to butene, the orange color of bromine water disappears, and a colorless dibromo compound is formed. This reaction is known as the bromine test and is used to distinguish alkenes from other types of hydrocarbons.

On the other hand, benzene does not react with bromine water under normal conditions because the aromatic ring is more stable and less reactive than a carbon-carbon double bond. Benzene can react with bromine only in the presence of a catalyst, such as FeBr₃, and the reaction is a substitution rather than an addition.

Therefore, butene can be distinguished from benzene by its reaction with bromine water (Option B). The other options, hydrochloric acid (Option A), potassium sulfate (Option C), and sodium hydroxide (Option D), do not react with either butene or benzene in a way that would distinguish them.

Correct Answer: C. POS.

Explanation

(a) King Hiram's Role towards the Building of the Temple (1 Kings 5: 1 - 12):

(i) King Hiram of Tyre was a friend of David .

(ii) He sent congratulatory message to Solomon upon hearing of Solomon's succession to David.

(iii) Solomon in. turn sent word to Hiram about David's unsuccessful attempts to build the temple because of wars that faced him.

(iv) David's initiatives included the acquisition of the land for the site and arrangements for the supply of timber from Phoenicia.

(v) Solomon decided to build the temple in fulfillment of his father's aspirations.

(vi) Thus Solomon, after introducing himself to Hiram, had a treaty of friendship made to forge peace and unity.

(vii) Solomon then made a request for the sale of cedar and cypress wood to him by Hiram.

(viii) He further requested that the servants of the king of Tyre work together with his servants as he was prepared to pay them.

(ix) Hiram agreed and decided to have his servants cut the woods into rafts and get them for shipping down the Mediterranean sea to Lebanon.

(x) And when this was done, Solomon was to pay by supplying food for the king's household.

(xi) Thus Hiram supplied Solomon with all the timber of cedars and cypress wood desired while Solomon gave Hiram wheat and oil.

(xii) The building of the temple provided a proper religious centre for the worship of Yahweh in Israel.

(b) Benefits of making friends:

(i) promotes love and peace.

(ii) provides support for one another in times of need/mutual co-operation.

(iii) encourages shared responsibility/teaming up to do things.

(iv) promotes trust, faithfulness and commitment.

(v) opens up job opportunities

(vi) offers expertise knowledge/skills etc.

(vii) offers protection/defence and security.

(viii) promotes companionship

Correct Answer: D. retailers

Correct Answer: B. stores of value

Correct Answer: D. Queen Amina

Explanation

The British colonial policies contributed to the rise of nationalism in West Africa in many ways. These include:

(i) The crown-colony policy was not acceptable to the nationalists, e.g. both the legislative and executive councils were dominated by British officials. Only illiterate African chiefs were nominated as members of the legislative council.

(ii) The land law was unfavourable to the chiefs and people.

(iii) The whites adopted colour bar and social segregation, e.g. housing estates, recreational facilities, hospital and schools.

(iv) Economic inequalities between 9. the whites and the indigenes especially in commercial enterprises contributed a lot to the rise of nationalism, e.g. granting of loans by banks, the activities of companies like UAC, UTC and P.Z.

(v) There was little or no opportunities for the advancement of the Africans in the public service.

(vi) There was inequality in wages between whites and natives especially in commercial enterprises were.

(vii) Provision of educational facilities through missionaries made the Africans politically conscious.

(viii)There opportunities for the Africans to participate in government through constitutional developments.

Correct Answer: C) Lord Lugard

Explanation

Option A, Dr. Nnamdi Azikiwe, was a Nigerian nationalist and the first President of Nigeria, but he did not introduce indirect rule.

Option B, Sir James Robertson, was a British colonial administrator who served as Governor-General of Nigeria, but he did not introduce indirect rule.

Option C, Lord Lugard, is the correct answer. He was a British colonial administrator who was instrumental in the founding of Nigeria and implemented indirect rule as a means of governing the country.

Option D, Mungo Park, was a Scottish explorer who traveled extensively in West Africa in the late 18th and early 19th centuries, but he did not introduce indirect rule in Nigeria.

It is important for students to understand the concept of indirect rule and how it impacted Nigeria's colonial history. They should also be familiar with other key figures in Nigeria's history, such as Nnamdi Azikiwe and Lord Lugard.
