Seketul tumbuhan air (Hydrilla) dalam larutan natrium hidrogenkarbonat; sebuah lampu pada 30 cm, 20 cm dan 10 cm memberi tiga keamatan cahaya. Gelembung oksigen yang dibebaskan dikira selama 2 minit pada setiap keamatan.
Kenal pasti pembolehubah dimalarkan (tetap) dan pembolehubah bergerak balas dalam eksperimen ini.
A water plant (Hydrilla) in sodium hydrogencarbonate solution; a lamp at 30 cm, 20 cm and 10 cm gives three light intensities. Oxygen bubbles released are counted for 2 minutes at each intensity.
Identify the constant (fixed) variable and the responding variable in this experiment.
