(Let's discuss one popular SPM question example as shown below):
SPM 2014: Terangkan apakah yang berlaku kepada sel darah merah (SDM) pada R (5 markah)
SPM 2014: Explain what happens to the red blood cells in R (5 marks)
2. Kita akan gunakan teknik LAOS untuk menulis jawapan.
(We shall use LAOS technique to write our answer).
L = LARUTAN - huraikan larutan samada hipotonik, hipertonik, atau isotonik.
(describe the solution either hypotonic, hypertonic, or isotonic one).
A = AIR - bahan yang meresap ialah air, bukan bahan lain!
(water as diffusing substance, nothing else!)
O = OSMOSIS - air meresap masuk/keluar secara osmosis.
(water diffuses into/out of cell via osmosis)
S = SEL (huraikan keadaan sel pada akhir proses - segah/flasid/krenasi/hemolisis)
(describe the cell condition in the end - turgid, flaccid, crenation, haemolysis)
3. Diagram proses:
 |
| SDM dalam air suling yg bersifat hipotonik (RBC in hypotonic distilled water) |
 |
| Air meresap masuk sel (Water diffuses into cell) |
 |
| Sel mengalami hemolisis (Cell undergo haemolysis) |
