1. What is the study of the geographical distribution of organisms and the factors that influence it known as?

Correct answer: C

Rationale: Biogeography is the scientific discipline that focuses on studying the geographical distribution of organisms and the factors that influence their patterns of distribution. This field investigates the reasons behind why species are located where they are, taking into account historical events, ecological interactions, and physical geography. Paleontology (option A) specifically deals with the study of fossils and the history of life on Earth, mainly focusing on extinct organisms. Taxonomy (option B) is the science that involves classifying and naming organisms based on their characteristics. Population genetics (option D) is concerned with the study of genetic variation and evolutionary processes within populations of organisms. Therefore, in the context of studying the distribution of organisms across space and time, biogeography is the most appropriate choice.

2. What is the formula to calculate work?

Correct answer: A

Rationale: Work is defined as the product of the force applied to an object and the distance over which the force is applied. The formula to calculate work is represented by Work = Force × Distance, where force is the applied force on an object and distance is the displacement over which the force is applied. Therefore, the correct formula to calculate work is Work = Force × Distance. Choice B, 'Work = Mass × Velocity,' is incorrect because work involves force and distance, not mass and velocity. Choice C, 'Work = Power × Time,' is incorrect because work is not directly calculated using power and time. Choice D, 'Work = Energy ÷ Time,' is incorrect because work is not typically calculated by dividing energy by time; rather, it involves the product of force and distance.

3. Which of the following best describes the process of osmosis?

Correct answer: B

Rationale: The correct answer is B. Osmosis is the process where water moves across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. Choice A is incorrect because osmosis does not involve movement against the concentration gradient. Choice C is incorrect because osmosis primarily involves the movement of water, not water and solutes together. Choice D is incorrect as osmosis specifically refers to the movement of water molecules, not large molecules, through a membrane.

4. Which of the following is NOT a property of a catalyst?

Correct answer: D

Rationale: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It remains unchanged after the reaction, which eliminates option B. A catalyst works by lowering the activation energy required for the reaction to occur, which eliminates option C. A catalyst does not create new products in a reaction; it only facilitates the conversion of reactants into products more efficiently. Therefore, option D is NOT a property of a catalyst.

5. Which of the following statements regarding the working of the heart is not correct?

Correct answer: B

Rationale: The correct answer is B because the heartbeat actually begins when the heart muscles relax, allowing the chambers to fill with blood. The contraction phase follows, which propels blood out of the heart. The other statements are accurate in describing the normal sequence of events in the heart's functioning: the atria contract to push blood into the ventricles, the valves close to prevent backflow of blood, and the ventricles contract to pump blood out of the heart.
