<!-- /wp:heading -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-1-anabolic-process"><strong>Question 1 – Anabolic Process</strong></h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Which of the following is an <strong>anabolic process</strong>?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. Excretion<br>B. Fermentation<br>C. Photolysis<br>D. Photosynthesis<br>E. Transportation</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p> <strong>Answer:</strong> D. Photosynthesis<br> Anabolic processes build up molecules rather than break them down. For example, photosynthesis combines carbon dioxide and water to form glucose, making it anabolic. By contrast, fermentation is catabolic.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-2-kidney-diseases"><strong>Question 2 – Kidney Diseases</strong></h3>
<!-- /wp:heading -->

<p>The following are kidney diseases <strong>except</strong>:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. Diuresis<br>B. Hepatitis<br>C. Kidney stones<br>D. Nephritis<br>E. Oedema</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p> <strong>Answer:</strong> B. Hepatitis<br>Hepatitis is a disease of the <strong>liver</strong>, not the kidney. In contrast, nephritis and kidney stones directly affect kidney function.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-3-reflex-action"><strong>Question 3 – Reflex Action</strong></h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>The following are involved in reflex action <strong>except</strong>:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. Receptors<br>B. Sensory neurons<br>C. Brain<br>D. Motor neurons<br>E. Effectors</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Answer:</strong> C. Brain<br> Reflexes are automatic responses coordinated by the spinal cord. As a result, the brain is not directly involved.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-4-plant-transport"><strong>Question 4 – Plant Transport</strong></h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Which tissue is responsible for transporting water in plants?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. Phloem<br>B. Xylem<br>C. Cortex<br>D. Epidermis</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Answer:</strong> B. Xylem<br>Xylem vessels transport water and minerals from the roots upward. On the other hand, phloem transports food.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-5-photosynthesis"><strong>Question 5 – Photosynthesis</strong></h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Which of these is the correct equation for photosynthesis?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. CO₂ + H₂O → Glucose + O₂<br>B. CO₂ + O₂ → Glucose + H₂O<br>C. Glucose + O₂ → CO₂ + H₂O<br>D. CO₂ → O₂ + Water</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p> <strong>Answer:</strong> A. CO₂ + H₂O → Glucose + O₂<br>This process captures sunlight to form glucose while releasing oxygen. Therefore, photosynthesis is both essential for plants and beneficial to animals.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-6-human-nutrition"><strong>Question 6 – Human Nutrition</strong></h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Which vitamin prevents rickets in children?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. Vitamin A<br>B. Vitamin B<br>C. Vitamin C<br>D. Vitamin D</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Answer:</strong> D. Vitamin D<br>Vitamin D helps the body absorb calcium. Consequently, it prevents weak bones and deformities like rickets.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading" id="h-question-7-blood-circulation"><strong>Question 7 – Blood Circulation</strong></h3>
<!-- /wp:heading -->

<p>Which component of blood is responsible for clotting?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A. Plasma<br>B. Platelets<br>C. Red blood cells<br>D. White blood cells</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->

<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p> <strong>Answer:</strong> D. Plants<br>Biotic factors are living things such as plants and animals. In contrast, temperature and soil pH are abiotic factors.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>A. Nucleus<br>B. Ribosome<br>C. Mitochondrion<br>D. Chloroplast</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->

<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>GCE Biology questions test your knowledge of <strong>cells, organs, ecology, and vital life processes</strong>. However, with consistent practice, you’ll begin to recognize patterns in how questions are asked. Furthermore, answering with explanations improves both your confidence and accuracy.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>In summary, use this practice set as a revision guide. Combine it with past questions, and you’ll be well-prepared to score high in your GCE Biology exam.</p>
