Biology 2 Passage Sample Questions
Summary
The lesson focuses on understanding and analyzing a complex scientific passage related to diabetes insipidus, its types, and the physiological effects of ADH and aldosterone on the body, using a series of practice questions to enhance comprehension and application of biological concepts in preparation for the GRE exam.
- Introduction to diabetes insipidus, distinguishing between central and nephrogenic types based on ADH production and response.
- Analysis of a water deprivation test to identify patients with central or nephrogenic diabetes insipidus through changes in urine osmolarity.
- Exploration of ADH's additional actions beyond water retention, emphasizing its role in increasing blood pressure through vascular smooth muscle constriction.
- Discussion on Conn's syndrome (primary hyperaldosteronism), highlighting its effects such as hypertension and hypokalemia, and the physiological implications on membrane excitability and action potential production.
- Application of core knowledge to extrapolate and answer complex questions, demonstrating the critical thinking required for GRE-level biological sciences questions.
