Solution
Read the following passage carefully and answer the question on it.
The chalkboard is by far the commonest teaching aid used at virtually.all levels of education from the nursery to the university. It is the most enduring teaching aid and perhaps will be the most difficult to replace. In the advanced-countries of the world, it is being threatened by the overhead protector. However, the overhead projector requires constant supply of electricity which is one reason we cannot rely on it yet. The chalkboard used to be black, which why the name "blackboard" stuck for ages; but today, there are boards of various colours: blue, green, even white.
Now, most chalkboards are made of wood nailed to the wall, instead of the concrete board made of cement and f ine sand that was more common. some are also made of metal. The chalkboard has the advantages of low cost, availability and ease of maintenance, usually involving mere cleaning and occasional retouching of the surface with the renovator. However, if the board is metal, the felt marker should be protected against drying by replacing the cap When it is not in use. The major drawback in the use of the chalkboard is that the information on it can only be temporary. if there is only one board for the class, it is usually impossible to leave the information there for more than a few hours, since other teachers would want to use it.
It is not easy to draw complex diagrams showing minute details, such as part's of the body and contours, unless one is a good artist. Where one has succeeded with laborious illustrations, using different colours, it could be painful when the board has to be cleaned by the next teacher. However, there are nowadays various innovations, including foldable boards made of plywood, which allow teachers more room to leave their materials for longer periods.
Finally, it is a great disadvantage that during the course of teaching, more time is spent writing on the board than when one is using the overhead projector. So, in all, more time is needed for any lesson when one uses the board rather than the overhead projector.
(a) Why does the writer use the word chalkboard rather than blackboard most of the time?
(b) Mention two different types of chalkboard that have been in use.
(c) Mention two disadvantages of the chalkboard.
(d) Why should the cap of the felt pen be re placed when the pen is not in use?
(e) The major drawback in the use of the chalkboard (i) What grammatical name is given to the expression as it is used in the passage? (ii) What is its function?
(f) ...it is being threatened by the overhead projector... (i) What figure of speech is used in this expression? (ii) What does it mean? (g) For each of the following words, find another word or phrase which means the same and which can replace it as it used in the passage: (i) virtually (ii) constant (iii) various (iv) temporary (v) laborious (vi) room

Solution
Read the following passage carefully and answer the questions on it.
Dele groaned and got out of bed. There was no clock on the mantle-piece and the room was still dark, but he knew that he was already late for work, probably by up to an hour. He was a commercial bus driver and had to get started as early as 5.00 a.m. and go almost non-stop until about 9.00 p.m. to be able to make the daily returns that the bus owner demanded.
On the previous day, he had attended an all-night party - a late uncle's burial ceremony - where he had drunk himself almost senseless before crawling home on his face and hurried off to work, but not before carefully fastening on his upper left arm the amulet he had always worn for protection against accident. A similar amulet hung concealed under the steering column of his bus. On his way, still feeling groggy, he caught his left toe against a stump and had some misgiving. It was a bad sign, and he was supposed to go back home and then set out again. But there was no time for that now, so he hurried on. At the bus station, Dele quickly loaded his bus and sped off without any of the necessary checks on the vehicle. He had to make up for lost time. It was the rush hour, so the bus was overloaded as it often was, with many passengers hanging on to the doors. The tyres were threadbare, the brakes were faulty and the road was wet, but, still feeling a little sleepy, Dele sped on. Many passengers protested about his reckless driving, but he would not listen. After all, didn't he have protection against accident?
As the vehicle took the last turn before its destination, Dele saw a broken-down truck blocking his side of the road. Under normal circumstances, he could have brought the bus safely to a halt, but the circumstances were far from normal. The careening bus hit the parked vehicle, swerved wildly across the road and plunged into a ditch. Dele's surprise before he sank into oblivion was the failure of his supposed protective amulets.
(a) Why did Dele wake up late?
(b) ...he caught his left tow against a stump and had some misgiving. What does this tell us about Dele?
(c) Give two reasons why Dele drove recklessly.
(d) Why was Dele unable to stop his faulty vehicle?
(e) What was Dele's condition after the accident?
(f) After all; didn't he have protection against accident? What literary device is used in this expression?
(g) ...wildly across the road... (i) What is the grammatical name given to the expression as it is used in the passage? (ii) What is its function? (h) For each of the following words, find another word or phrase which means the same and which can replace it as it is used in the passage: (i) probably (ii) returns (iii) groggy (iv) misgiving (v) threadbare (vi) reckless.

Reading Comprehension, Summary & Composition
Solution
Read the following passage carefully and answer the question on it. .
You cannot expect to go through life without meeting problems. Difficulties, perplexities and frustrations are an inevitable part of human experience. Accepting this idea of the inevitability of problems will help you to approach them in a robust frame of mind rather than thinking that you are a victim specially singled out by a malignant fate.
When confronted with a problem, the first thing to do is to gather i all relevant data to get acquainted with all the facts of the case. Then write down exactly what the problem is, stating it simply in black and white. This gives you something definite with which to come to terms. The problem is, assessed and you will now have something concrete to deal with.
Next, give serious thought to the problem, making sure that such thought does not degenerate into worry as worry accomplishes nothing. Aim at clear, dispassionate thought, viewing the problem as if it were friend's and not your own. Look at it from all angles and from the view point. of all concerned. You court disaster if you are entirely selfish in your outlook. The single important purpose of all this is to discover all possible solutions to the problem.
Having examined the problem broadly and impartially, carefully examine all the possible solutions or courses of action. the knowledge that you have done this will keep you from useless regrets later, when you can remind yourself that all possible courses of action were examined and you chose what appeared to be the best. Next, eliminate all proposed solutions which are seen on further thought to be impracticable.
You will now find that your list has been whittled down to two or three possibilities. At this stage it is often a good plan to get out into the open air. go for a walk or a ride, preferably somewhere with wide horizons. There out in the open, review the problem afresh. You will find it appears much less formidable. Ask yourself how the difficulty will appear in ten years time, or even one! This fresh review enable you to make a final choice as you turn to the remaining solutions and. before you return home, decide which you are going to adopt. As you go to sleep that night, let your last thoughts be upon your decision. If, in the morning, you still feel it is the best one to take, go ahead.
If you have a friend you think is capable of giving sound advice, consult him. Do this before your final decision, so that you will have the benefit of his views before you decide. Talking things over with another is always a great help. It enables you to isolate the problem and to decide which are the important factors. Even if the friend offers no advice, a sympathetic word will help you, you will see them in a clearer light. Some will appear impossible even while you speak. Alternatively, one will appear most attractive.
In dealing with problems, remember the time factor. Although some problems solve themselves in time, and delaying tactics are therefore the best form of action for them, most other problems generally get more complicated the longer they are left. You should therefore get to grips with problems immediately they occur.
All told, reasonable foresight and imagination can prevent many problems ever arising. Tact, thoughtfulness and responsible conduct can also keep life largely problem-free.
(a)In six sentences. one for each, summarise the steps to be taken when faced with a problem and state why each step is necessary.

Cell Structure, Organization & Cell Division
Solution
The organelle common to both plant and animal cells is the
A
centrioles
B
plasmalemma
C
cell wall
D
chloroplast
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Centrioles are primarily found in animal cells, where they play a crucial role in cell division by organizing microtubules and forming the spindle fibers that separate chromosomes. While centrioles are generally absent in higher plants, they can be found in some lower plants and in the male gametes of certain plant species.
The plasmalemma, also known as the cell membrane or plasma membrane, is a biological membrane that separates the cell's interior from the external environment, regulating the movement of materials and facilitating communication.The plasmalemma (or cell membrane) is a common structure found in both plant and animal cells, but not regarded as an organelle, rather the outer boundary of the cell, separating the inside from the outside environment, and it's a membrane, not an organelle.
Cell walls are a defining feature of plant cells, but are absent in animal cells. Plant cells have a rigid cell wall surrounding the cell membrane, which provides structural support and protection. Also, a cell wall is not considered an organelle, but rather a non-membrane-bound, extracellular structure that provides support and protection to cells, particularly in plants, fungi, and bacteria.
Plant cells have chloroplast and cell walls, whereas animal cells do not. Plant cells must be rigid to maintain their posture, and they require chlorophyll, which is found in the chloroplast, for food production.

Solution
Which of the following is likely to have a higher concentration of the mitochondria?
A
Sperm cell
B
white blood cell
C
Egg cell
D
Red blood cell
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Sperm cells are likely to have a higher concentration of mitochondria than white blood cells, red blood cells or even the egg cells because sperm require a significant amount of energy for motility, while white blood cells have a more diverse range of energy needs.
Sperm cells, specifically in their midpiece, contain a high concentration of mitochondria, which are the "powerhouses" of the cell, producing the energy (ATP) needed for the sperm to swim and travel towards the egg.
Mitochondria, often called the "powerhouses of the cell," are organelles that generate energy in the form of ATP (adenosine triphosphate) through cellular respiration, a process that breaks down glucose and other molecules to produce energy.

Solution
The hyphal wall of fungi is rigid owing to the
A
cell wall
B
lignin
C
cellulose
D
chitin
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
The rigidity of fungal hyphal walls is primarily attributed to chitin, a complex polysaccharide, along with other polysaccharides like glucans, and proteins, which together form a robust structural framework.
This is a major structural component of fungal cell walls, similar to how it forms the exoskeleton of insects and crustaceans. Chitin is a homopolymer of \beta-1,4-linked N-acetylglucosamine units, providing significant strength and rigidity.

Angiosperms and gymnosperms belong to the class
A
schizophyta
B
spermatophyta
C
pteridophyta
D
bryophyta
medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
Both angiosperms (flowering plants) and gymnosperms (conifers, cycads, etc.) are considered to be part of the group of seed-bearing plants, often referred to as "spermatophytes" or "seed plants".
Spermatophytes (Seed Plants) broadly refers to the group of plants that produce seeds as their reproductive structure.
Angiosperms are flowering plants, characterized by having their seeds enclosed within a fruit (e.g., apples, berries, nuts).
Gymnosperms are plants that produce "naked seeds," meaning their seeds are not enclosed within a fruit, and are often found on cones (e.g., pine cones).

medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
The pulmonary veins are the only veins in the body that carry oxygen-rich (or oxygenated) blood, bringing it from the lungs back to the heart.
Typically, veins carry deoxygenated blood (blood that has given up oxygen to the body's tissues) back to the heart. The pulmonary veins are an exception to this rule, as they transport oxygenated blood from the lungs to the left atrium of the heart.

The function of the fluid - filled pericadium is to
A
reduce the friction caused by the pumping movements of the heart
B
supply the heart with organisms from attacking the heart
C
prevent disease organism from attacking the heart
D
reduce the intensity of the pumping
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The fluid-filled pericardium, the sac surrounding the heart, functions to cushion and protect the heart from outside forces, reduce friction during heartbeats, and prevent excessive heart expansion. The pericardium, with its fluid-filled space, helps to limit the heart's ability to expand too much, which can occur when there's an overfilling of blood or other fluids, potentially leading to low cardiac output.

A
respiring in the absence of oxygen
B
liberating oxygen on their own
C
living and consuming oxygen
D
being killed by the alcohol produced
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The bubbles of carbon (IV) oxide produced by yeast cells in a glucose solution containing pyrogallol indicate that the yeast cells are performing anaerobic respiration (fermentation), breaking down glucose to produce carbon dioxide and ethanol.
Yeast, like many microorganisms, can survive and reproduce in the absence of oxygen through a process called fermentation.During fermentation, yeast breaks down glucose (a type of sugar) into simpler molecules, such as ethanol and carbon dioxide, releasing energy in the process.
