1 (g) [KB0605 - Predicting]
Question Mark Scheme Marks
1(g) Able to predict the number of students based on the following aspects:
P1 : Correct prediction ( Number of student with free earlobe increases /
more than 14 / (any value more than 14 but less than 50 ) / more than the
students with attached earlobe )
P2 : Free earlobe is dominant trait
P3 : More samples / students used
Sample answers:
The number of student is more than 14 . Free earlobe is a dominant trait.
More samples are used ( will increase the probability )

1 (h) [KB0609 - Define Operationally]
Question Mark Scheme Marks
1(h) Able to define variation based on the following aspects:
D1: Differences of characteristics / traits /phenotype in humans / male
students
D2 : Type of earlobe
D3 : Dominant and recessive trait // Hypothesis statement
Sample answer:
Variation is differences of characteristics in humans which is the type of
earlobe. Number of students with free earlobe trait is higher than the
number of students with attached earlobe.

Question Criteria Marks
2(i)
Able to state a problem statement correctly based on the following aspects:
P 1: Manipulated variable - Humidity
P 2: Responding variable - Population size of garden snail
P 3: Relationship in question form
Sample answers :
1. Does humidity affect the population size of garden snail?
2. What is the effect of humidity to the population size of garden snails?
3
Able to state the problem inaccurately based on two criteria:
Sample answers :
1. Does humidity affect the garden snail? ( P1 and P3 only )
2. Does the population size of garden snail different? ( P2 and P3 only )
2
Able to state the of problem statement at idea level based on one criterion:
P1or P2 only
Sample answer :
1. Population size of garden snail is different.
2. Humidity affects the garden snail.

2(ii) Hypothesis
Question Criteria Marks
2(ii) Able to state a hypothesis correctly based on the following criteria:
P1: Manipulated variable -Humidity
P2: Responding variable - Population size of garden snail
P3: Relationship
Sample answer :
1. When humidity is higher/lower, the population size of garden snail is
higher/lower
2.When humidity is higher/lower, the population size of garden snail is
lower/higher. (wrong conclusion)

Sample answer :
1. Humidity affects the population size of garden snail. ( P1 and P2 only )
2. When humidity is higher, the garden snail is more. ( P1 and P3 only )
Able to state a hypothesis at idea level.
P1 or P2 only
Sample answer :
1. Humidity affects the garden snail.
2. Population size of garden snail is different.
3. The higher the population size of garden snail, the higher the humidity.
