11. ...metabolic process, they also help in the production of A. Energy Metabolic processes are fundamental to life, and a primary outcome of many metabolic pathways (like cellular respiration) is the production of energy (ATP) to fuel cellular activities. 12. The main function of the pancreatic amylase is A. To break down starch and convert it to maltose Pancreatic amylase is an enzyme produced by the pancreas that specifically breaks down complex carbohydrates like starch into simpler sugars such as maltose. 13. In which organ of the human body is the enzyme pepsin located? D. Stomach Pepsin is a protease enzyme that functions in the highly acidic environment of the stomach to begin the digestion of proteins. 14. So far, Earth is the only habitable planet due to the fact that there is presence of oxygen, water and... B. Suitable temperature The presence of liquid water, oxygen, and a suitable temperature range are critical factors that make Earth habitable, allowing for complex life to thrive. 15. 'They do not have moons around them' is a feature of A. Inner planets Among the inner planets (Mercury, Venus, Earth, Mars), Mercury and Venus are notable for having no moons. 16. Which of the following can be considered as a producer in an ecosystem? C. Mango tree Producers are organisms, typically plants like a mango tree, that create their own food through photosynthesis, forming the base of the food chain. 17. Which of the following comes into being as a result of fungi reactions in an ecosystem? A. Mushrooms Mushrooms are the fruiting bodies of many types of fungi, which play a crucial role as decomposers in ecosystems. 18. A tape worm sucking nutrients from the host as it resides in it while the host is being harmed is an example of: B. Parasitism Parasitism is a symbiotic relationship where one organism (the parasite, e.g., tapeworm) benefits by deriving nutrients from another organism (the host) at the host's expense. 19. Oceans and seas make up the ... water habitat. C. Marine Oceans and seas are characterized by saltwater and are collectively referred to as marine habitats. 20. Which of these will best describe coastal habitats of an ecosystem? D. The region where the land meets the sea Coastal habitats are defined as the areas where terrestrial environments (land) interact with marine environments (sea), including beaches, cliffs, and estuaries. 21. Mensah Abugri, a farmer at Kintampo decides to grow maize, groundnut and okra on the same piece of land. This method of farming is best described as: C. Mixed cropping Mixed cropping involves growing two or more different crops simultaneously on the same piece of land, as described by Mensah Abugri's practice. 22. Atta-Minah decides to rear animals, produce crops and other products without the use of synthetic chemical fertilizers and pesticides, transgenic species or antibiotics and other chemicals. Although, he is being mocked for doing that, what economical benefit is he likely to get? A. Attraction of high price in foreign markets Farming without synthetic chemicals and other artificial inputs is known as organic farming. Organic products often command higher prices, especially in international markets, due to consumer demand for natural and chemical-free produce. 23. A body of mass 14.0 kg is hanged on a mango tree 12.0 m above the ground. What is the potential energy with respect to the ground? [g = 10m/s²] Step 1: Identify the formula for potential energy. PE = mgh Step 2: Substitute the given values into the formula. PE = (14.0\, kg) × (10\, m/s^2) × (12.0\, m) Step 3: Calculate the potential energy. PE = 1680\, J The calculated potential energy is 1680\, J. This value is not among the provided options. However, if we assume there was a typo in the question and the height was intended to be 20.0\, m instead of 12.0\, m, then the calculation would be: PE = (14.0\, kg) × (10\, m/s^2) × (20.0\, m) = 2800\, J This matches option B. Given the requirement to select from the options, we choose the most likely intended answer assuming a common typo. B. 2800J 24. Kinetic energy is the energy that a body has by virtue of its motion. What is the formula to calculate the kinetic energy? B. KE = (1)/(2)mv^2 The formula for kinetic energy, which is the energy of motion, is half the product of the mass (m) and the square of the velocity (v). 25. The following colours namely red, orange, yellow, green, blue, indigo and violet (ROYGBIV) made up: C. White light The acronym ROYGBIV represents the colors of the visible spectrum, which are the constituent colors that make up white light when combined or dispersed. 26. In an electronic circuit, it store electricity and then discharge it back into the circuit when there is a drop in the voltage, so I am? A. A Capacitor A capacitor is an electronic component designed to store electrical energy in an electric field and release it when needed, such as during a voltage drop. What's next?
