Let us take a look the 2025 BECE Integrated Science Theory Questions and Answers (Trial Test 2)
ii. A pair of scissors, a wheelbarrow and forceps are classified as first, second, and third class levers, respectively. Based on what factor are the simple machines classified? (2 marks)
They are classified based on the relative positions of the pivot (fulcrum), effort, and load. 2 marks
2b. i. What is Transplanting?
m. Transplanting is the process of moving a plant from one growing location to another. 2 marks
ii. State four precautions to observed when transplanting pepper. (3 marks)
2b. ii. Precautions to Observe When Transplanting Pepper
v. Avoid damaging roots
vi. Transplant during cool parts of the day
vii. Water plants before and after transplanting
viii. Prepare the soil properly
ix. Maintain proper spacing 1 mark each × any 4 = 4 marks
2c. i. What are Magnetic Lines of Force?
l. Magnetic lines of force are imaginary lines that represent the direction and strength of a magnetic field. 2 marks
2 (c) iiState any three metals that are exception. (3 marks)
2c. ii. Five Metals That Are Exceptions to Magnetic Attraction
20. Aluminum
21. Copper
22. Gold
23. Silver
24. Brass 1 mark each × any 3 = 3 marks
d. Explain any two of the major processes in the carbon cycle. (4 marks)
2d. Four Major Processes in the Carbon Cycle
v. Photosynthesis:
Photosynthesis is the process by which green plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This process provides the essential energy and organic compounds necessary for plant growth and the sustenance of almost all life forms on Earth.
vi. Respiration:
Respiration is the process by which living organisms, including plants and animals, convert glucose and oxygen into energy, carbon dioxide, and water. This energy is vital for all cellular activities and overall survival.
vii. Burning/Combustion:
Combustion is the process of burning organic matter, such as wood, coal, or fossil fuels, which releases energy, carbon dioxide, and various other gases into the atmosphere. This process is a significant source of energy for human activities but also contributes to air pollution and greenhouse gas emissions.
viii. Decay/Decomposition:
Decay or decomposition is the breakdown of dead organic matter by microorganisms such as bacteria and fungi. This process recycles essential nutrients back into the environment, making them available for use by living organisms and maintaining the balance of ecosystems.
1 mark for process and 1 mark for explanation × any 2 = 4 marks
