Which part of the human brain is responsible for processing auditory information? Topic: Nervous System Occipital lobe Parietal lobe Temporal lobe Frontal lobe None 2. In a reflex arc, which type of neuron is directly responsible for activating the effector? Topic: Reflex Action Sensory neuron Motor neuron Interneuron Association neuron None 3. Which hormone is involved in the regulation of calcium levels in the blood? Topic: Endocrine System Insulin Glucagon Parathyroid hormone Thyroxine None 4. Which hormone is responsible for the fight or flight response and how does it affect the body? Topic: Hormones Insulin - Decreases blood glucose levels Thyroxine - Increases metabolic rate Adrenaline - Increases heart rate and blood pressure Melatonin - Regulates sleep cycle None 5. How do gibberellins affect plant growth and development? Topic: Plant Hormones Promote root growth Inhibit seed germination Stimulate stem elongation Delay leaf senescence None 6. Which type of plant movement is caused by chemical stimuli? Topic: Coordination in Plants Phototropism Geotropism Chemotropism Thigmotropism None 7. What is the primary function of the myelin sheath in neurons? Topic: Human Nervous System To transmit electrical impulses To protect the neuron To insulate the axon and speed up nerve impulse transmission To connect neurons to blood vessels None 8. How do interneurons differ from sensory and motor neurons? Topic: Types of Neurons They transmit impulses to muscles They carry impulses from sensory organs to the brain They connect sensory and motor neurons within the central nervous system They produce neurotransmitters None 9. Which part of the brain is responsible for maintaining homeostasis? Topic: Brain Parts Cerebrum Cerebellum Medulla oblongata Hypothalamus None 10. Why are reflex actions faster than voluntary actions? Topic: Reflex Arc They involve fewer neurons They bypass the brain and are processed in the spinal cord They require conscious thought They use chemical signals None 11. Which hormone is responsible for the aging and dropping of leaves in plants? Topic: Plant Growth Auxin Gibberellin Cytokinin Ethylene None 12. Which hormone is crucial for regulating the body's metabolism? Topic: Hormones in Animals Insulin Thyroxine Adrenaline Oxytocin None 13. What is the role of the synapse in the nervous system? Topic: Nervous Coordination Transmit electrical impulses within the neuron Connect neurons to blood vessels Allow communication between neurons by transmitting chemical signals Protect neurons from damage None 14. How does an action potential travel along a neuron? Topic: Structure of Neuron As a chemical signal As an electrical impulse As a wave of depolarization As a mechanical vibration None 15. Which part of the brain is involved in higher cognitive functions such as thinking, reasoning, and memory? Topic: Human Brain Cerebellum Brainstem Cerebrum Medulla oblongata None 16. What is the primary function of the pancreas in the endocrine system? Topic: Endocrine System in Humans Regulate blood calcium levels Control metabolic rate Produce insulin and glucagon to regulate blood glucose levels Stimulate growth and development None 17. What is the effect of auxin on the shaded side of a plant stem? Topic: Phototropism Inhibits cell elongation Promotes cell elongation Causes cells to die Has no effect on cell growth None 18. Which part of the brain is primarily involved in regulating involuntary actions such as heart rate and breathing? Topic: Human Nervous System Cerebrum Cerebellum Medulla oblongata Hypothalamus None 19. Which hormone is secreted by the adrenal cortex and helps in regulating metabolism and immune response? Topic: Endocrine System Insulin Glucagon Cortisol Adrenaline None 20. Which lobe of the brain is responsible for processing visual information? Topic: Human Brain Frontal lobe Parietal lobe Temporal lobe Occipital lobe None 21. What is the primary advantage of having reflex actions? Topic: Reflex Action They are slow and deliberate They involve conscious thought They protect the body from harm by providing quick responses They require complex processing in the brain None 22. Which part of the brain is involved in the regulation of hormonal secretions by the pituitary gland? Topic: Coordination in Animals Cerebellum Medulla oblongata Hypothalamus Thalamus None 23. Which plant hormone is primarily responsible for promoting seed germination and breaking dormancy? Topic: Plant Responses Auxin Gibberellin Cytokinin Ethylene None 24. What is the role of the peripheral nervous system (PNS)? Topic: Nervous System Control involuntary actions Transmit signals between the central nervous system and the rest of the body Process sensory information Coordinate voluntary movements None 25. Which structure in the brain acts as a relay station for sensory and motor signals? Topic: Human Brain Cerebrum Thalamus Cerebellum Medulla oblongata None 1 out of 25 Time's up
