Experience the Quality With Free PAX Exam Questions That Helps Candidates Pass

Solar energy is renewable because it is continuously replenished by the sun. Coal, oil, and natural gas are fossil fuels, which are nonrenewable and deplete over time. On PAX, science questions often integrate environmental awareness. Renewable = solar, wind, hydro, geothermal; Nonrenewable = fossil fuels. A strategy is to classify quickly: “Does it regenerate naturally on a human timescale?”

Area = ½ × base × height = ½ × 12 × 5 = 30 cm². Option A is correct. Option B is the full product without halving. Option C doubles again. Option D is miscalculated. On PAX, always apply ½ for triangle area.

During photosynthesis, plants absorb carbon dioxide and water, using sunlight to produce glucose and oxygen. Thus, oxygen is released as a by-product, making B correct. Option A is what plants take in, not release. Nitrogen (C) is abundant in the atmosphere but not exchanged in photosynthesis. Hydrogen (D) is involved internally but not released. PAX science emphasizes contrasts between photosynthesis and respiration: plants release O₂, animals consume O₂.

“Genuine” means real or authentic. Its opposite is “fake.” Options A, B, and D are synonyms. On PAX, antonym questions often test simple, everyday vocabulary with precise opposites.

The heart, with its four chambers, pumps blood through pulmonary and systemic circuits. The brain directs function, lungs exchange gases, and liver detoxifies. PAX science often emphasizes cardiovascular function basics.
