Explanation

(i) An eclipse is a shadow that results from the obstruction of light from the sun by the moon or the earth.

(ii) Types of eclipse:

-Eclipse of the sun or solar eclipse.

-Annular eclipse

- Eclipse of the moon or lunar eclipse.

(b i) The eye defect is long sight or hypermetropia.

(ii) The type of lens to correct the defect is convex or converging lens.

(iii) Power of lens = \(\frac{1}{f} = \frac{1}{0.1} = dioptre(D)\)

(c) Velocity of an echo = \(\frac{2d}{t}\)

d = \(\frac{vt}{2} = \frac{340 \times 5 \times 10^{-3}}{2} = 0.952 m\)

(d) M = \(\frac{v}{u}\)

U = \(\frac{V}{M} = \frac{9}{0.6} = 15cm\)

\(\frac{1}{f} = \frac{1}{u} + \frac{1}{v} = \frac{1}{15} + \frac{1}{-9}\)

f = -22.5cm

Correct Answer: C. 0.95:1

Correct Answer: D. Unitary

Correct Answer: D) contrasting antigens and antibodies meet

Explanation

This question is asking about what happens during transfusion agglutination. Transfusion is the process of transferring blood from one person to another. Agglutination is a clumping together of particles, in this case, blood cells. The question is asking what causes this clumping to occur during transfusion. The correct answer to this question is Option D: contrasting antigens and antibodies meet. Antigens are proteins found on the surface of red blood cells, and antibodies are proteins produced by the immune system to attack foreign particles. When blood with different antigens is transfused into a person, their immune system may recognize the new antigens as foreign and produce antibodies to attack them. If the antibodies come into contact with the antigens on the surface of the red blood cells, they can cause the blood cells to clump together, leading to agglutination. It's important to match blood types before transfusion to ensure that the antigens on the surface of red blood cells are compatible with the antibodies in the recipient's blood. If incompatible blood is transfused, it can cause a dangerous reaction called hemolytic transfusion reaction, which can lead to kidney failure, shock, and even death. To learn more about blood transfusion, blood types, and the immune system, please see the relevant sections of your Biology textbook.

Explanation

1-When comes the Help of Allah, and Victory,

2- And thou dost see the people enter Allah.s Religion in crowds,

3- Celebrate the praises of thy Lord, and pray for His Forgiveness: For He is Oft-Returning (in Grace and Mercy).

1. When comes the Help of Allah, and Victory,

The victory in this verse refers to the conquest of Mecca. There can be no victory without Allah’s Help.

Victory comes only by the Help of Allah. Verily! Allah is Mighty, Wise.

In Surah al-Imran, Allah says:

If Allah is your Helper none can overcome you, and if He withdraws His Help from you, who is there who can help you after Him? In Allah let believers put their trust.

Prior to the conquest of Mecca, Allah gave Muslims the good news of this great victory in Surah al fatah, at the occasion of the Treaty of Hudaybiyyah (an agreement that took place between Prophet Muhammad (PBUH) and the Quraysh of Mecca although most of the clauses of the treaty were against Muslims).

Verily We have granted you a manifest Victory.

Allah guaranteed this victory to Muslims after a long period of trials and patience.

This verse also indicates that Allah has completed the mission of His Messenger by making him successful in conveying the message.

Narrated Ibn Abbas (RA):

Umar (RA) asked the people regarding Allah’s Statement: “When comes the Help of Allah (to you O Muhammad against your enemies) and the conquest of Mecca?” They replied, “It indicates the future conquest of towns and palaces (by Muslims).” Umar said, “What do you say about it, O Ibn Abbas?” I replied, “(This Surah) indicates the termination of the life of Muhammad. Through it he was informed of the nearness of his death.”

2. And you see the people enter Allah’s Religion in crowds,

Truly, the conquest of Mecca opened a new chapter in the history of Islam. Earlier, many of the Arab tribes resisted joining with the Prophet Muhammad (PBUH). They wanted to see who would emerge victorious between him and the Quraysh. They reasoned that if the Quraysh were victorious, then Prophet Muhammad (PBUH) was not really a prophet! But if he was victorious, they reasoned, then he must really be a Messenger of Allah. [6]

Narrated Hz Amr bin Salama (RA):

And the Arabs (other than Quraysh) delayed their acceptance of Islam till the Conquest (of Mecca). They used to say. “Leave him (i.e. Muhammad) and his people Quraysh: if he overpowers them, then he is a true Prophet.” So, when Mecca was conquered, then every tribe rushed to embrace Islam.

3. Celebrate the praises of your Lord, and pray for His Forgiveness: For He is Oft-Returning (in Grace and Mercy).

Allah is the One who gives victories, so thanks should be given to Him. This is why in this verse Allah tells us to celebrate His praises, and offer thanks to Him.
