This biology exam emphasizes foundational concepts, including cellular structures, photosynthesis, and nutrient transport in plants. Key topics include osmosis experiments, the role of enzymes in respiration, and hormonal regulation during the menstrual cycle. It explores comparative anatomy, such as lungfish versus human circulatory systems, and investigates diabetes management and amino acid requirements. Experimental methods, like measuring gas production in yeast respiration, are tested alongside data interpretation and graphing skills. The paper integrates biological principles with practical applications, fostering critical thinking in human health, plant physiology, and molecular biology contexts.
