◍ List ONE key difference between 'diffusion' and 'facilitated
diffusion'. Answer: Diffusion — the movement of small substances
from a high to low concentration.
Facilitated diffusion — the movement of larger substances from high
to low concentration with the aid of transmembrane proteins
◍ Explain what is meant by a 'free radical'. Answer: Free radicals are
unstable and highly reactive molecules. They lack an electron in their
atomic structure, which can be donated by antioxidants.

Answer: Any two of the following
Colour: dark red
Respiration: aerobic
Myoglobin and mitochondria: highest
Duration: Longest
Good for: endurance
Diameter: small
◍ Describe the difference between muscle properties 'excitability' and
'extensibility'. Answer: Excitability → ability to conduct an electrical
current. Nerve impulses cause muscles to contract.
Extensibility → ability to stretch without being damaged.
◍ Describe specifically how the muscular system maintains 'body
posture'. Answer: Stabilising joints, posture, and balance through
continued partial muscle contraction.
