Correct Answer: B

Rationale: The correct answer is B because not all fungi are parasitic and harmful to humans. Some fungi are beneficial, while others are neutral. A is correct as fungi can be unicellular or multicellular. C is true as fungi are crucial in breaking down organic matter. D is accurate as some fungi, such as mushrooms, are consumed as food. Overall, choice B is false because it wrongly generalizes all fungi as harmful, which is not the case.

Correct Answer: A

Rationale: The correct answer is A: Convergent evolution. Dinosaurs evolving feathers before birds supports convergent evolution because it shows unrelated organisms (dinosaurs and birds) developing similar traits (feathers) independently to adapt to similar environmental pressures. This scenario is not an example of divergent evolution (B) where related organisms evolve different traits. It also does not demonstrate coevolution (C) where two species influence each other's evolution. The extinction of dinosaurs due to an asteroid impact (D) is not directly related to the evolution of feathers in dinosaurs before birds.

Correct Answer: C

Rationale: The correct answer is C: Electroencephalogram (EEG). EEG is used to record the electrical activity of the brain by placing electrodes on the scalp. It is specifically designed to measure brain waves. A CAT scan (A) uses X-rays to create detailed images of the brain's structure, not its electrical activity. An MRI scan (B) uses magnetic fields to produce detailed images of the brain's anatomy, not its electrical activity. X-ray (D) is used to visualize bones and dense tissues, not brain activity. EEG is the only option that directly measures the brain's electrical activity, making it the correct choice.

Correct Answer: D

Rationale: The correct answer is D: Aorta. The aorta is responsible for pumping oxygenated blood to the body. This happens after the oxygenated blood leaves the left ventricle of the heart through the aortic valve. The aorta is the largest artery in the body and carries blood to all parts of the body, supplying oxygen and nutrients. The other choices are incorrect because: A: Right ventricle pumps deoxygenated blood to the lungs. B: Left ventricle pumps oxygenated blood to the body. C: Pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.
