when living cells or blood take in food or oxygen
light energy hits a surface and is converted into heat energy
what happens when digested food particles pass from the digestive system into the bloodstream.
to build up
the process of building up or gathering together
has a pH less than 7, for example stomach acid.
changes to organisms which allow them to survive or to do their job
glucose from food reacts with oxygen to produce energy
has a pH greater than 7.
air sacs in the lungs where gaseous exchange happens
determines how loud or soft a sound is
enzyme responsible for the breakdown of starch.
chemical reactions that release energy without oxygen
Angle of incidence
angle between the normal and an incident ray
Angle of reflection
angle between the normal and a reflected ray
Angle of refraction
angle between the normal and a refracted ray
chemicals produced by certain white blood cells, help to destroy microbes
the end point of the digestive system.
distance an object appears to be below the surface of a transparent material (due to refraction)
blood vessels that carry blood away from the heart
the smallest bit of something
force pulling towards something
nerve that carries electrical signals from the ear to the brain so we can hear
