Human Nervous System & Homeostasis MCQs Reflex Arc, Eye, Hormones, Tropisms A Level & O Level Bio
Welcome to Learn With Miss Sehrish 🌿 In this video, we solve 14 important MCQs from the topics of Nervous System, Reflex Action, Eye Structure & Function, Hormones, Tropisms, Temperature Regulation, and Homeostasis. Perfect for A Level & O Level Biology revision and exam preparation! 🧠 Topics Covered in This MCQ Video This lesson includes detailed explanations for: Reflex Arc Pathway (sensory → relay → motor neurone) Neuron structure & function (dendrites, axon, myelin sheath) Effect of exercise on water loss (skin vs kidneys) Eye anatomy – iris, pupil, retina, optic nerve Adrenaline effects (fight or flight response) Effect of drinking iced water at high temperature Plant Tropisms (gravitropism / geotropism) Hormone-producing organs Impulse pathway in reflex diagrams Light-sensitive part of eye (retina) Plant response experiment controls Why mammals sweat? Accommodation in the eye (focusing far vs near objects) Capillary loop changes when cold (vasoconstriction) Each MCQ is explained with reasoning, helping students understand why the correct answer is correct. 🎯 Learning Outcomes By the end of this video, students will be able to: ✔ Identify the correct order of neurones in a reflex arc ✔ Label & understand parts of a neurone ✔ Understand eye structures and their functions ✔ Explain hormone actions and their effects ✔ Understand sweating, thermoregulation, and homeostasis ✔ Define tropisms (phototropism & geotropism) ✔ Explain vasodilation and vasoconstriction ✔ Improve exam-style MCQ solving skills Perfect for CAIE, IGCSE, GCSE, AQA, Edexcel, O Levels, and A Levels. 👩🏫 Who This Video Helps This MCQ series helps: A Level Biology students O Level / IGCSE Biology students Students preparing past papers Students who need quick revision before exams Anyone struggling with control & coordination, nervous system, eye, homeostasis A Level Biology MCQs, O Level Biology MCQs, Human Nervous System MCQs, Reflex Arc explained, Eye structure biology, Adrenaline effects biology, Tropism MCQs, Homeostasis MCQs, Thermoregulation, Sweat response, Plant experiment control, Biology exam preparation, CAIE Biology past paper questions, Learn With Miss Sehrish Biology. 👉 If this video helps, please LIKE 👍, COMMENT 💬 and SUBSCRIBE 🔔 to stay updated with the next classes in the series! #OLevelBiology #ALevelBiology #BiologyMCQs #ReflexArc #NervousSystem #EyeBiology #Homeostasis #Tropisms #Hormones #IGCSEBiology #CAIEBiology #LearnWithMissSehrish
