DECLINE IN DISCIPLINE AND MORALITY IN NIGERIA

There. is no doubt that there is a general decline in discipline and morality in our society. Everyday there are reported cases of indiscipline and immorality. In fact, it has reached a frightening proportion. The youths disrespect the elders and one often hears of students beating up their teachers. Cultism and all other forms of immoral acts are now common in our society. Policemen and women brazenly collect bribe while government officials embezzle public funds

The causes of indiscipline and immorality in our society are not far-fetched. The seed of indiscipline is sown at home when youths begin to disrespect their parents. From there, they grow to disobeying constituted authorities. The high point is when they begin to behave immorally at home and in public. In other words, indiscipline and immorality start from home. Nowadays, parents have no time for their children's upbringing. Parents go out early in the morning and come back late in the night. Some parents are drunkards and quarrelsome. They exhibit many other bad characters not worthy of emulation. Therefore, the home influence is a great factor.

Similarly, societal influence is another strong factor causing a decline in the level of discipline. The society which is immoral and which encourages indiscipline cannot produce disciplined youths. Here and there. Nigerians acquire illegal wealth by crooked means. Public officials, more often than not, embezzle public funds and it is a common sight to see policemen and women collecting bribe publicly. They even aid and abet armed robbery and smuggling.

Nevertheless, this ugly situation can be reversed. If we want to eradicate indiscipline and immorality in our society, all hands must be on deck. Since indiscipline and immorality begin from home, parents have a lot of work to do. They should consider it a priority to train their children. In addition to this, the religious bodies should be ready to do a lot too. They should educate the youths and the elderly alike on the vices of crimes and immorality. Our people must be told and encouraged to be disciplined and of good morals in their dealings. The leaders and the elders should live a life worthy of emulation and set good moral standards. The society can change for the better if our public officials in government can be disciplined and upright. If the changes start from the top, the level of discipline and morality will be raised.

Correct Answer: A. less of the other goods is produced

Explanation

A production possibility curve (PPC) is a curve which shows various combinations of the amounts of two goods which can be produced within the given resources. It shows that, as a firm produces more of a particular good, less of the other combination would be produced. For instance, if two different products say X and Y are meant to be produced from a particular raw material, if the producer produces more of commodity X from the available material, the materials used in the production of commodity Y would be less. The producer can decide to produce equal amount of each product, but if more of one is produced, less of the other product would be produced.

Correct Answer: D. 0.56dm³

Correct Answer: B. Turn.

Correct Answer: D. 120

Explanation

\(\frac{^{n}P_{5}}{^{n}C_{5}} = \frac{n!}{(n-5)!} ÷ \frac{n!}{(n-5)!5!}\)

= \(\frac{n!}{(n-5)!} \times \frac{(n-5)!5!}{n!} = 5! = 120\)

Correct Answer: A. the final image is inverted

Correct Answer: B) I and III are rostellum and suckers

Explanation

In the given image of a tapeworm, we can see different parts of its anatomy, including proglottids, hooks, rostellum, and suckers. Let's identify these parts and their functions: Proglottids: These are the flat, rectangular segments that make up the body of the tapeworm. They contain both male and female reproductive organs, allowing the tapeworm to reproduce. In the image, proglottids are not labeled. Hooks: These are small, sharp structures present on the rostellum that help the tapeworm attach itself to the host's intestine. In the image, hooks are labeled as II. Rostellum: This is a small, knob-like structure present at the anterior end of the tapeworm. It contains hooks that help in attachment to the host. In the image, the rostellum is labeled as I. Suckers: These are circular, muscular structures present around the rostellum. They also help the tapeworm attach itself to the host's intestine. In the image, suckers are labeled as III. Now, let's analyze the given options: Option A: I and II are proglottides and hooks - This option is incorrect because I is the rostellum, not the proglottides. Option B: I and III are rostellum and suckers - This option is correct because I is indeed the rostellum, and III are the suckers. Option C: III and IV are hooks and proglottids - This option is incorrect because III are the suckers, not the hooks. Option D: II and IV are hooks and rostellum - This option is incorrect because II are the hooks, but IV is not labeled in the image, and the rostellum is labeled as I. So, the correct answer is Option B: I and III are rostellum and suckers.

Correct Answer: D. yam and potato shots growing out through the same window

Explanation

(a)

(b)

(c)(i) x = -2.9 or 1.9

(ii) \(y + (3 - 2x - 2x^{2}) = 11 - 2x - 2x^{2}\)

\(y = 11 - 2x - 2x^{2} - 3 + 2x + 2x^{2}\)

\(y = 8\)

\(\therefore x = \text{-1.8 or 0.8}\)

(iii) \(y = 11 - 2x - 2x^{2}\)

\(\frac{\mathrm d y}{\mathrm d x} = -2 - 4x\)

Gradient at x = 1 : \(-2 - 4(1) = -2 - 4 = -6\)
