Which of the numbered structures contain chlorophyll?

• A 1.

• B 2.

• C 3.

• D 4.

9. The part of the eye responsible for image formation is the:

• A Cornea.

• B Pupil.

• C Retina.

• D Choroid.

Quick Study Tips for These O-Level Questions

• Don’t Fall into the Bile Trap (Question 5): This is one of the most common mistakes students make! Always remember that the liver produces bile, while the gall bladder is only responsible for storing and concentrating it.

• Food Tests Reagents (Question 4): Memorizing color changes is key. Million’s reagent specifically turns brick-red in the presence of proteins. If the question asked about Benedict’s solution, you’d be looking for reducing sugars!
