Correct Answer: B. Marketing research

Explanation

(a)(i) Appreciation in agricultural practices refers to the gain or increase in the value or worth of an asset as the asset is being used over time e.g growing crops, young farm animals, cash crops appreciate.

(ii) Depreciation refers to the loss or reduction in the value or worth of an asset as the asset is being used overtime. e.g Tractor, drinkers, tools, implements do depreciate.

(iii) Salvage value: This is the amount which an asset is sold off when it is longer economical to keep or when the cost of maintenance of the asset is too high.

(b)(i) The salvage value of the tractor N3,000.00 i.e. the price at which e tractor was sold off.

(ii) Total depreciation = Cost price - salvage value of the tractor = N12,000.00- N3,000.00 = N9,000.00

(iii) Annual depreciation = total depreciation/no of years OR = Cost price - Salvage value/life span of tractor = N12,000/1987 - N3000/1978 =N9000/9years = N1000.

(iv) Appreciation: The tractor suffered a loss or reduction in worth. 9 years. Therefore, appreciation is nil.

Correct Answer: C. Entrepreneurship

Correct Answer: C. Lysosome

Correct Answer: A. Free on Board (FOB)

Correct Answer:

Explanation

(a)(i) A saturated solution is one which will not dissolve any more of the solute at the given temperature in the presence of crystals of the solute.

(ii) Preparation: To a given volume of distilled water at a temperature above 30°C add NaNO\(^3\) crystals with stirring until no more dissolves, cool to 30°C and decant the clear solution on top

(iii) The two techniques are

(a) Evaporation to dryness

(b) Crystallization]

(b(i) Concentration of solutinn. KNO\(_3\) = \(\frac{404}{101}\) = 4.0mol dm\(^3\)

KClO\(_3\) = \(\frac{245}{122.5}\) = 2.0mol dm\(^3\)

From the information provided KCIO\(_3\) will crystallize out at 101 60°C

while KNO\(_3\) will remain in solution since its solubility at 60°C (5.14 mol dm\(^{-3}\)) is higher than the amount in solution.

(ii) Excess salt = (2.0 -1.61) = 0.39 mole. Mass that will separate = 0.39 x 122.5 = 47.78g

(c)(i) Two salts which cause hardness of water are

(a) Calcium hydrogen trioxocarbonate (iv) Ca(HCO\(_3\))\(_2\).

(b) Calcium tetraoxosulphate(VI) CaSO\(_4\).

(ii) If temporary hard water is boiled in kettle the calcium hydrogen trioxocarbonate(IV) salt causing the hardness decomposes forming the insoluble calcuim trioxocarbonate(iv) which coats the inside of the kettle;

Ca(HCO\(_3\))\(_{2(aq)}\) -> CaCO\(_3\) + H\(_2\)O\(_{(l)}\) + CO\(_{2(g)}\) Soluble insolubl

soluble insoluble

Correct Answer: A. herd

Correct Answer: D) forced labour

Explanation

Solomon was a wise king in Israel who made many good decisions during his reign. However, he also made some unwise decisions. This question is asking us to identify one of those unwise decisions. We are given four options to choose from, and we need to select the correct one.

Option A suggests that building the palace was an unwise decision, but this is not correct. Building the palace was a good decision because it provided a place for the king to live and work.

Option B suggests that building the temple was an unwise decision, but this is also not correct. Building the temple was one of Solomon's greatest achievements, and it was a wise decision because it provided a central place of worship for the people of Israel.

Option C suggests that felling of timber was an unwise decision, but this is not the answer we are looking for. Felling of timber was a necessary activity for building and construction during that time.

Option D is the correct answer. Forced labour was an unwise decision of Solomon because it put a heavy burden on the people of Israel. Solomon forced people to work without pay, which caused suffering and hardship for many. This decision went against God's commandments to treat all people with fairness and kindness.

In summary, the correct answer to this question is option D. Solomon's unwise decision was the use of forced labour. To learn more about this, please read the relevant sections of the recommended textbooks.
