Biology: Control and Coordination for NTSE Prep

Succeeding in the NTSE biology section requires a deep, conceptual understanding of how organisms respond to their environment. This text-based course breaks down the complex mechanisms of biological control and coordination into clear, digestible lessons. You will build a solid foundation in both human and plant physiology, transitioning from basic definitions to analyzing exam-style application questions. By studying the precise pathways of electrical and chemical signals, you will develop the analytical skills needed to score high on NTSE Stage 1 and 2. What you'll learn: Understand the fundamental structure and function of neurons, synapses, and the central nervous system; Explain the mechanism of reflex actions and reflex arcs with step-by-step biological pathways; Compare the functions of major human endocrine glands and their hormone feedback loops; Analyze plant movements and phytohormones, including auxins, gibberellins, and abscisic acid; Apply scientific reasoning to solve multiple-choice questions modeled after recent NTSE exam patterns. The course starts with foundational definitions of stimuli and responses, progresses through the human nervous and endocrine systems, and concludes with plant coordination and exam-style practice scenarios. This course is designed for high school students preparing for competitive science exams, with no prior advanced biology knowledge required.
