BTEC LEVEL 2 APPLIED SCIENCE
EXAMINED UNIT BIOLOGY EXAM
2024
Name the process by which our bodies respond to changes in the
environment to keep the conditions inside our bodies the same - CORRECT
ANSWERS-Homeostasis
Name the two systems that controls the internal environment of the body -
CORRECT ANSWERS-nervous system and endocrine system
Name the part of the nervous system that is not involved in a reflex action -
CORRECT ANSWERS-Brain
Give an example of a reflex - CORRECT ANSWERS-Dropping a hot pan
Give an example of a voluntary response - CORRECT ANSWERS-Chewing
when food is in your mouth
Give the two structures that make up the CNS - CORRECT ANSWERS-brain
and spinal cord
Give 2 differences between involuntary and voluntary responses - CORRECT
ANSWERS-Involuntary uses spinal cord but voluntary uses brain; voluntary is
slower than involuntary; Involuntary is a relax
Describe a reflex arc - CORRECT ANSWERS-Receptor detects stimuli,
impulses send down sensory neurone to spinal cord and passed via relay
neurone to motor neurone. The motor neurone passes impulses to the
muscle which contracts and brings about the response
How are impulses carried across the synapses - CORRECT ANSWERS-
chemical diffusion
Which neurones make up the peripheral nervous system - CORRECT
ANSWERS-Sensory and motorPowered by TCPDF (www.tcpdf.org)
