Flashcard 1: What is the role of the brain in an animal sense-and-response model?
Answer: It processes information and decides on an action. Central control center that interprets and plans responses.
Flashcard 2: What is a stimulus in an animal sense-and-response model?
Answer: A change in the environment that can be detected. Any environmental change that triggers sensory detection.
Flashcard 3: What is the role of sense organs in an animal sense-and-response model?
Answer: They detect stimuli and gather information. First step where environmental changes are detected.
Flashcard 4: What is a response in an animal sense-and-response model?
Answer: An action or behavior that happens after processing. Final step where the body acts on brain's decision.
Flashcard 5: Which sense organ detects light to provide information for the brain to process?
Answer: Eyes. Specialized organs containing photoreceptors for vision.
Flashcard 6: Which sense organ detects sound vibrations to provide information for the brain to process?
Answer: Ears. Contains receptors that convert sound waves to nerve signals.
Flashcard 7: Which sense organ detects chemicals in the air for the sense of smell?
Answer: Nose. Contains olfactory receptors that detect airborne molecules.
Flashcard 8: Which sense organ detects chemicals in food for the sense of taste?
Answer: Tongue. Contains taste buds that detect dissolved chemicals.
Flashcard 9: Which sense organ detects touch, pressure, and temperature for the brain to process?
Answer: Skin. Largest organ with receptors for multiple sensations.
Flashcard 10: Which body system carries messages from sense organs to the brain and back to muscles?
Answer: The nervous system. Network of neurons connecting all body parts to brain.
Flashcard 11: What are nerves in a sense-and-response model?
Answer: Body pathways that carry messages to and from the brain. Bundles of neurons that transmit electrical signals.
Flashcard 12: Identify the correct response type: Is pulling a hand away from a hot surface a voluntary or involuntary response?
Answer: Involuntary response. Automatic reflex that doesn't require conscious thought.
Flashcard 13: Which option best matches the model: loud thunder → ears → brain → what response helps protect the animal?
Answer: Startle and move to a safer place. Protective response to sudden, potentially dangerous sound.
Flashcard 14: Which option completes the model: smell of smoke → nose → brain → what response is most likely?
Answer: Move away from the smoke source. Safety response to potential fire danger signal.
Flashcard 15: Which option completes the model: bright light → eyes → brain → what response protects the eyes?
Answer: Blink or squint. Automatic reflex protecting eyes from damage.
Flashcard 16: Which option completes the model: very cold air → skin → brain → what response helps keep warm?
Answer: Shiver. Body's automatic response to generate heat.
Flashcard 17: Identify the missing step: stimulus → sense organ → → response
Answer: Brain processes information. Critical step where sensory input becomes action plan.
Flashcard 18: Which option is the best model for a rabbit hearing a predator: stimulus, sense organ, brain action, response?
Answer: Sound → ears → process danger → run or hide. Complete model showing predator avoidance behavior.
Flashcard 19: Which option correctly labels a model arrow: sense organ → brain represents what kind of information transfer?
Answer: Messages carried by nerves to the brain. Neural signals traveling along nerve pathways.
Flashcard 20: Which sense organ detects light and sends visual information to the brain?
Answer: Eyes. They convert light waves into electrical signals for the brain.
Flashcard 21: What are the three main steps in the sense–brain–response model for animals?
Answer: Sense organs receive input; brain processes; body responds. This sequence shows how animals detect, process, and react to their environment.
Flashcard 22: Which sense organ detects chemicals in the air and sends smell information to the brain?
Answer: Nose. It has receptors that detect airborne chemical molecules.
Flashcard 23: Which sense organ detects chemicals in food and sends taste information to the brain?
Answer: Tongue. Taste buds detect dissolved chemicals in saliva.
Flashcard 24: Which sense organ detects touch, pressure, heat, and pain and sends signals to the brain?
Answer: Skin. It contains various receptors for different physical sensations.
Flashcard 25: What is the correct order of these steps: response, brain processes, sense organ detects?
Answer: Sense organ detects → brain processes → response. Information flows from sensing to processing to action.
Flashcard 26: Identify the stimulus in this model: A loud clap makes a rabbit run into its burrow.
Answer: The loud clap (sound). The stimulus is what triggers the sense organs to send signals.
Flashcard 27: Identify the response in this model: A loud clap makes a rabbit run into its burrow.
Answer: Running into the burrow. This is the action taken after the brain processes the sound.
Flashcard 28: Which sense organ receives the stimulus: Bright light causes a person to blink?
Answer: Eyes. Light receptors in eyes detect brightness changes.
Flashcard 29: Which part processes the information: Smelling smoke makes a person leave the room?
Answer: The brain. It interprets the smell signal and decides to leave for safety.
Flashcard 30: Choose the response: Touching a hot pan causes a hand to pull away. What is the response?
Answer: Pulling the hand away. This protective reflex removes the body part from danger.
