AQA GCSE Biology revision
questions 2025-2024 A + GRADED
EXAM
, Homeostasis - CORRECT ANSWERS-The process of maintaining the constant
internal environment.
Motor Neurone - CORRECT ANSWERS-Motor Neurones connect the CNS to the
Effectors and take impulses away from CNS.
Sensory Neurone - CORRECT ANSWERS-Sensory Neurones connect sense
organs with the Central Nervous System.
Relay Neurone - CORRECT ANSWERS-Relay Neurones are present in the CNS
and occur between the sensory and motor neurons for distant transmission of
Impulses.
Reflex Actions - CORRECT ANSWERS-It is the automatic response of the body to a
stimulus, where the message from the sensory neurones is passed to the spinal
chord instead of brain.
Knee Jerk Reflexes - CORRECT ANSWERS-An example of a reflex action that is
rapid, quick, automatic, and instantaneous without conscious thoughts.
Synapse - CORRECT ANSWERS-Message is transmitted by chemicals.
Brain - CORRECT ANSWERS-It is the Central information processing organ of our
body, and acts as the command and Control System.
Cerebrum - CORRECT ANSWERS-It is nearly 80% part of the brain responsible for
consciousness, memory, intelligence, and language.
Cerebellum - CORRECT ANSWERS-It lies behind the cerebrum and above the
medulla oblongata, responsible for muscle coordination and balance.
Medulla Oblongata - CORRECT ANSWERS-It is the oblong cylindrical part of the
brain that forms the hindermost part and controls unconscious activities like heart
rate and breathing.
Brain Scan - CORRECT ANSWERS-Magnetic Resonance Imaging (MRI) helps to
take the Images of different parts of the brain and relating it with loss of functions of
the individual.
Accommodation - CORRECT ANSWERS-Ability of eye to adjust the focal length of
the lens to make clear image of the objects lying at varying distances.
Myopia - CORRECT ANSWERS-Short sightedness where the image falls in front of
the retina of the eye, corrected by concave lens.
Hypermetropia - CORRECT ANSWERS-Long sightedness where the image falls
behind the retina of the eye, corrected by convex lens.
