Explanation

Constitutional evolution of Federalism up to 1954 include:

(i) In 1914, Lord Lugard amalgamated the Southern and Northern Protectorates for easy administration.

(ii) Also in 1922, Clifford Constitution made the provision for a Legislative Council for the colony and Southern protectorate of Nigeria only.

(iii) The three provinces became known as three regions - Northern, Western and Eastern regions. This introduction came in 1946, by Arthur Richards in his constitution. Though regional assemblies were constituted, they had no legislative powers.

(iv) Legislative powers were given to regional assemblies, though on specific issues, with final approval from the central government. Macpherson Constitution brought these changes in 1951.

(v) Lyttleton constitution established a true federal structure in Nigeria in 1954. Powers were shared between central and regional governments with exclusive powers for the central government, concurrent for both governments and residual powers for the regions.

Correct Answer: A. 3

Correct Answer: A. London -> Moscow -> Baghdad

Correct Answer: B. x ≤ -1, 1 ≥ x ≥ 2

Correct Answer: A. -25^oC

Explanation

\(\frac{440 - 380}{680 - 380} = \frac{0 - x}{100 - x}\)

= -25^oC

Explanation

(a) Difference between subsistence agriculture and commercial agriculture

Subsistence Agriculture

• Production is mainly for family consumption
• Less capital is required
• Uses family labour/unskilled labour
• Use of local breeds of animals
• Use of local crop varieties
• Hardly use agro-chemicals/Cultural methods are used to control pests and diseases
• Records are rarely kept Use of primitive/local tools
• Poor housing facilities for rearing animals
• Peasant farmers are involved
• Doer not require improved processing facilities
• Does not involve any marketing Uses crude storage facilities
• Yield per unit area is low
• Food crops are produced
• Small area of land is cultivated
• Use of inorganic fertilizers is limited

Commercial Agriculture

• Production is mainly for sale
• Huge amount of capital is required
• Skilled/hired labour is employed
• Use of exotic/improved breeds of animals
• Use of improved crop varieties
• Mostly use agro-chemicals
• Records are kept Mechanized/use of machines
• Modern housing facilities for rearing animals
• Farmers involved may be rich
• Requires improved processing facilities
• Requires organised market Uses modern storage facilities
• Yield per unit area is high
• Cash crops are produced
• Large area of land may be cultivated
• Frequent use of inorganic fertilizers

(b) Advantages and Disadvantages of sources of farm power

(i) Wind :

Advantages

- Running cost is low

- Wind is safe to use

-Wind is a renewable source of energy

- Wind power is environmentally friendly

Disadvantages

-Wind energy converters work only during windy period and as such lie idle during less windy months/ Excessive variation in wind regimes can adversely affect the cost effectiveness of wind energy

-Too weak a wind force cannot be used for any work Success in exploitation of wind energy highly depends

on the specific site

- Wind mills occupy a large portion of land

- Requires high technical expertise

- Initial cost may be high

(ii) Internal Combustion Engine:

Advantages

- It is versatile/can be used for many farm operations

- Efficient source of power

-Not weather dependent

Disadvantages

-A high capital investment is required

- It requires specialized skills in its operation and maintenance

- In developing countries, there is inadequate spare parts for machines

-It contributes to the degradation of the environment/ It Exhaust gases pollute the environment

-Use is subject to to vagaries of fuel shortage

(iii) Electricity

Advantages:

-A very efficient source of farm Power

-it is versatile, with many valued uses

- It is a clean source of power •

-A large amount of energy can be supplied

- It is a fairly reliable source of farm Power

Disadvantages

-High capital outlay to set up

- Very dangerous to operate

- In developing countries, supply cannot be guaranteed at all time

-Needs technical know-how '

-Maintenance cost is high

Correct Answer: A. bearing of risks

Correct Answer: B. holozoic

Explanation

Holozoic nutrition is a type of nutrition in which organisms consume solid organic materials. This is the type of nutrition seen in most animals, where food is ingested and then broken down through digestion. This is different from symbiotic (where two organisms live together and benefit from each other), saprophytic (where organisms feed on dead and decaying matter), and parasitic (where one organism benefits at the expense of another) nutrition.

Correct Answer: A. 219 and 87

Explanation

\(^{235}_{92}U\) \(\to\) 4\((^{4}_{2}\alpha)\) + 3\((^{0}_{-1}e)\) + \(^{b}_{a}y\)

a + (4 + 2) + (3x - 1) = 92 \(\Rightarrow\) a = 87

b + (4 x 4) + (3 x 0) = 235 \(\Rightarrow\) b = 219

\(^{b}_{a}Y\) = \(^{219}_{87}Y\)

Correct Answer: B) He climbs into the sheepfold by another way

Explanation

This Christian Religious Knowledge question is asking you about the qualities of the good shepherd as described by St. John. The question is asking you to identify the quality that the good shepherd does not possess.

The options are:

Option A: He enters the sheepfold by the door

Option B: He climbs into the sheepfold by another way (Correct)

Option C: He leads the sheep out by the door

Option D: The gatekeeper opens the gate for him

According to St. John, the good shepherd has the qualities of entering the sheepfold by the door, leading the sheep out by the door, and the gatekeeper opens the gate for him. However, the correct option, option B, states that the good shepherd climbs into the sheepfold by another way. This means that the good shepherd does not have this quality.

The analogy of the good shepherd is often used in the Bible to describe how Jesus takes care of his followers. The good shepherd is a symbol of love, care, and protection. As Christians, we are expected to follow Jesus, our good shepherd, and allow him to guide and protect us.
