Correct Answer: B. aversions

Correct Answer: A) epiphytism

Explanation

In this Biology question, we are asked about the type of association that is shown by a fern growing on the stem of an oil palm. The options given are epiphytism, saprophytism, commensalism, and symbiosis. Epiphytism is a type of association where one plant grows on the surface of another plant, usually on a branch or stem, without harming the host plant. This association benefits the epiphyte plant as it gains access to sunlight and nutrients from the air and rain. Therefore, Option A (epiphytism) is the correct answer to this question because a fern growing on the stem of an oil palm is an example of epiphytism. Saprophytism, on the other hand, is a type of association where a plant obtains nutrients from dead or decaying organic matter. Commensalism is a type of association where one organism benefits, and the other is neither helped nor harmed. Symbiosis, on the other hand, is a close and long-term interaction between two different biological species, where both organisms benefit from each other. In summary, the correct answer to this Biology question is Option A (epiphytism) because a fern growing on the stem of an oil palm is an example of epiphytism, a type of association where one plant grows on the surface of another plant without harming it.

Correct Answer: B. playing on words

Explanation

Pun is the repetition of words with similar sound which has different meanings in the context in which they were used.

Correct Answer: B) gross profit

Explanation

a)(i) Storage Device: It is a piece of computer equipment/device/hardware/peripheral which can hold or store data/information. It can also be used to transfer data.

OR

Storage device can either be external/internal device used to hold/store data/information, for example, magnetic disk, diskette, flash drive, hard drive. DVD and VCD.

OR

Storage device is a digital medium/piece of computer equipment/device/hardware capable of storing/holding data/information either temporarily or permanently.

(i) Virtual Memory: This is the type of memory which allows a programmer to make a memory device behave as itf it has unlimited storage capacity. This supposed 'extra' memory is stored on secondary storage.

OR

Virtual memory is a technique by which additional memory is created on hard disc to compliment the activity of computer real memory.

OR

It is temporary.storage used by a computer to run programs that need more memory than it has.

OR

It is a memory management technique that provides an idealized abstraction of the storage resources that are actually available.

OR

It is a given machine which creates the illusion to users of a very large memory.

OR

It is a memory management capability of an operating system that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to dick storage.

(b)(i) Calculating Number of Bits Held by Each Device: 2KB (ii) Calculation of Total Capacity:

1 Kilobyte = 1024 bytes

1 byte = 8 bits

2 kilobytes = 2 x 1024 x 8

→ 16384 bits

2MB

1 Megabyte = 1024 kilobytes

1 kilobyte = 1024 bytes

2 kilobytes = 2 x 1024 x 8

1 byte = 8 bits

Therefore, 2MB = 2 x 1024 x 1024 x 8 = 16777216 bits

To add 2MB and 2KB together,

2Mb = 2 x 1024 x 1024 bytes

= 2097152 bytes

2KB = 2 x 1024 bytes

= 2048 bytes

Total in bytes = 2097152+ 2048 bytes

= 2,099,200 bytes

Explanation

f(x) =2xp\(^3\) + px\(^2\) + qx - 5

f(1) = 2(1)\(^3\) + p(1)\(^2\) + q(1) - 5

2+ p + q - 5;

p + q =3 -- (i)

f(-2) = 27

i.e, 2(-2)\(^3\) + p(-2)\(^2\) +q(-2) - 5 = 27

-16 +4p - 2q - 5 = 27

2p - q = 24--- (ii)

Solving(i) and (ii) Simultaneously

P = 9, q= -6
