Question 1
a) To investigate the relationship between the type of activity and the pulse
rate after activity in 1 minute.Untuk menyiasat hubungan di antara jenis aktiviti dan kadar denyutan
nadi selepas aktiviti dalam seminit.
b) type of activity
jenis aktiviti the pulse rate after activity in 1 minute.
kadar denyutan nadi selepas aktiviti dalam seminit.c) The type of activity more active, the pulse rate after activity in 1 minute
increases.Jenis aktiviti bertambah aktif, kadar denyutan nadi selepas aktiviti dalam
seminit bertambah.
More active the type of activity, more pulse rate after activity in 1 minute.
Lebih aktif jenis aktiviti, lebih banyak kadar denyutan nadi selepasaktiviti dalam seminit.
d) Because sleeping is less active activity.
Kerana tidur adalah aktiviti yang kurang aktif.Question 2
a) Because seeds of plant W is carried away by animals than seeds of plant
X.
Kerana biji benih tumbuhan W dibawa pergi oleh haiwan daripada biji

Buah tumbuhan W berwarna terang daripada buah tumbuhan X.c) Distance dispersal of seeds.
Jarak pencaran biji benih.d) The way to dispersal by animal, the distance dispersal of seeds further.
Cara pencaran oleh haiwan, jarak pencaran biji benih lebih jauh. The way to dispersal by explosive mechanism, the distance dispersal of
seeds nearer.Cara pencaran oleh mekanisma letupan, jarak pencaran biji benih lebih
dekat.
a) Decreases until C, increases.
Berkurang hingga C, bertambah.b) Type of light source.

Jenis bekas. Surrounding temperature.
Suhu persekitaran.c) 30°C - 10°C
d) The type of container steel, the water temperature reading low.
Jenis bekas logam, bacaan suhu rendah. The surrounding temperature increases, the water temperature reading
increases.Suhu persekitaran bertambah, bacaan suhu air bertambah.
a) 9
b) WTC: shape of structure
bentuk struktur WTKS: type of coin / type of material used
