The West African Senior School Certificate Examination (WASSCE) is a highly anticipated examination taken by final-year high school students across West Africa.
One of the key subjects in the WASSCE is Integrated Science, which tests students’ knowledge in various scientific disciplines such as Physics, Chemistry, Biology, and Earth Science.
Section B of the Integrated Science examination consists of structured questions that require students to apply their knowledge to solve problems and answer specific questions.
These questions are designed to test the student’s ability to think critically, analyze information, and draw conclusions based on scientific principles.
In this article, we will provide some sample WASSCE 2023 Integrated Science Section B questions that are of WAEC standard. These questions will cover different topics in science and will give students an idea of the type of questions they can expect to encounter on the actual examination.
By practicing these sample questions, students will be better prepared for the WASSCE and will have the confidence to tackle any challenges that may arise.
Solve The Following Questions
1. Define the term ‘wave’ and explain the difference between transverse and longitudinal waves. Provide examples of each type of wave and describe how they propagate through different mediums.
2. Discuss the concept of wave interference and its different types. Provide examples of constructive and destructive interference, and explain how they affect the amplitude of the resulting wave.
3. Explain the phenomenon of refraction and its relationship to wave speed and angle of incidence. Provide examples of how refraction occurs in different mediums, such as water and air.
4. Explain the concept of carrying capacity in an ecosystem. Give an example of how the carrying capacity of an ecosystem can be affected by human activities.
5. What is biomagnification, and how does it occur in food chains? Provide an example of a pollutant that can undergo biomagnification and the harmful effects it can have on animals and humans.
6. Describe the process of eutrophication in bodies of water. What are the causes and consequences of eutrophication, and what can be done to prevent or mitigate its effects?
7. Explain the difference between dominant and recessive traits in genetics. Using a Punnett square, illustrate the possible genotypes and phenotypes of offspring resulting from a cross between a homozygous dominant parent and a heterozygous parent for a particular trait.
8. Describe the process of meiosis and its importance in the formation of gametes. Explain how the process of crossing over during meiosis contributes to genetic diversity in offspring.
9. Discuss the role of mutations in genetic variation. Provide examples of different types of mutations, their effects on the DNA sequence, and how they can be inherited.
Make sure to solve these sample questions and prepare for your final examinations. We wish you all the best of luck.
