Correct Answer: C. Punnett square

Explanation

A Punnett square is a graphical representation used in genetics to predict the possible genotypes of offspring in a cross between two individuals. It is named after Reginald Punnett, a British geneticist who developed the method. In a Punnett square, the genotypes of the parents are represented on the top and left sides of the square. The possible combinations of alleles from each parent are then filled in the cells of the square to show the potential genotypes of their offspring.

Explanation

(a) Area of?PQR = \(\frac{1}{2}\) * b * 12 = 20

b = \(\frac{2 x 20}{12}\) = 3.33cm

|QR| = |UT| = 3.33cm

IPQ| = √(12\(^2\) + 5\(^2\))\(^2\) = 13cm

IRT| = |QU| = 12cm

From?RTS

sin 50°= \(\frac{12}{|RS|}\)

|RS| = \(\frac{12}{sin 50°}\) = 15.6649 cm

|TS| = \(\frac{12}{tan 50°}\) = 10.069cm

Perimeter = 13 + 3.33 + 15.6649 + 18.399

= 50.3939cm = 50cm (nearest whole number)

(b)Area= \(\frac{1}{2}\) (3.33+ 18.4004)12

6 (21.7304) = 130.3824cm\(^2\)

= 130 cm\(^2\) (nearest whole number)

Explanation

There are three forms of Hajj:Tamattu, Ifraad andQiran. For the purpose of this Hajj guide, we will use theTamattuform of Hajj, which is what the Prophet Muhammad (SAW) encouraged his followers to perform.

Before you arrive at Makkah to start Hajj, it’s important to make your intention (niyah) within your heart. The intention must be to perform the Hajj for the sake of Allah alone, with a desire for the Hereafter. It should not be done with the intention of being seen among others or for worldly gain.

Next, you’ll enter into the state ofihram (ritual purity). For men, this means wearing the designated white cloth with one piece wrapped around your shoulder and one around your waist. Ladies can wear any clothing of their choice but should ensure they observe the rules of hijab. Face coverings, however, are not permitted. Fully-covering shoes are also not permitted. Footwear must be in the form of sandals for both men and women.

In Ihram designated white cloth

Ihram is the spiritual state you enter once you have made the intention to go to Hajj. When over three million pilgrims descend into Makkah, there should not be any outwardly distinction between pilgrims. Everyone stands equal in the eyes of Allah (SWT), whether you’re rich or poor and irrespective of ethnicity. Hence, the rules around the clothing of Ihram are extremely simple, yet strict andmust be adhered to.

Throughout these holy days, we should also be particularly mindful of our behaviour and words. We should avoid smoking, engaging in sexual relations, swearing, shaving our hair and cutting our nails. We must also not use perfume or scented soaps.

Once you arrive at the holy Masjid al-Haram, in Makkah, you’re then ready to start the biggest spiritual journey of your life!

Tip: Carry a spare set of ihram if you can. As for sandals, I recommend investing in a decent pair of trekking sandals. They tend to be the most comfortable and practical, given that you will be walking long distances on tarmac as well as gravel. Try to get used to your sandals before you depart for Saudi so that you don’t break out in blisters or face discomfort once there.

Correct Answer: B. conduct of elections into local government offices

Correct Answer: A. 246cm

Correct Answer: B. fulfil all righteousness

Explanation

When Jesus was baptized by John the Baptist, it was to fulfil all righteousness. This act demonstrated Jesus' obedience to God's will and his identification with humanity. Though Jesus was sinless, he participated in the baptism to align with God's plan and set an example for others. This event is recorded in the Gospel accounts, including Matthew 3:13-17.

Explanation

(a) The positively charged conductor attracts the negative charges in the air and repels the positive charges i.e. the candle flame ionizes the air around it.

= 1.6 x 10\(^{-19}\) X 5.0 X 10\(^5\) x 0.2 x Sin 30°

= 0.8 x 10\(^{-1}\)

(c)(i)E = I (Rc + r)

9 = 4(Rc + 0.5)

R: =9/4-0.5

= 1.75Ω

(ii) Lost volt = Ir = 4.0 x 0.5 =2.0 V

V oltage across 2Ω and RΩ

V = 9.0 - 2.0 = 7.0V

Current in A\(_2\) = I\(_2\) =\(\frac{2}{VR}\)=7/2= 3.5A

Current in A\(_3\) = I\(_3\) = V/R = 7/14 = 0.5A

OR

A\(_3\) = A\(_1\) - A\(_2\)

= 4.0 - 3.5 = 0.5A

(iii) 1/RC =\(\frac{1}{R}\)+\(\frac{1}{R_2}\)

1/1.75 =\(\frac{1}{R}\)+ \(\frac{1}{2}\)

\(\frac{1}{R}\)= 1/1.75 - \(\frac{1}{2}\)

R = 14Ω

DearAdewale,

I am very happy to write this letter to you in a most respectful manner, fully conscious of the fact that you are studying well. How is your health and your studies? I hope that everything is running smoothly in your school. Dear friend, it is a thing of joy for me to write this letter to you after one year of silence between two of us. I could recalled that the last time I received your letter was on the 6th of April, 2021. This is not normal considering how closed we are to each other.

Dear Ade, I am writing this letter to intimate you of my future career and how it will be a beneficial to my country, Nigeria. I earnestly want to red medicine in the university. I want to be a medical doctor. This is a profession that I like, cherish and have passion for. I always envy medical practitioners because they are well-respected in the society. Though the profession is highly competitive, I have aptitude for science and desire to came for others.

As a medical doctor, i shall be beneficial to my country, Nigeria, by helping others in an incredibly significant way. When someone is sick or injured, his or her normal way of life is disrupted, as a doctor I have the incredible opportunity to restore these people's lives to normalcy and even save some from

death. Therefore, l being a medical doctor will be extremely rewarding to my country, Nigeria. As a medical doctor, I will have the ability to build meaningful relationships with my patients. By seeing my patients over and over again, I shall be able to build meaningful friendly relationships with them.

Again, if l am a medical doctor in the nearest future, I shall learn everything there is to know about the human body. I shall have the opportunity to study and further examine human body with the innovative technology. From the pumping of the hea
