My boy’s school science teacher, HOD told them that top school papers answer key usually have a lot of mistakes. Can’t use the answer keys, parents, teachers or tutors have to do the marking. I could only supply the correct answers for ACS. Don’t have the rest of the school papers.

7) 3
10) 1
13) 3
18) 4
21) 3
22) 4
23) 2
34) The height of the water left in the water
43a) male flower
b) Plant A. It’s big petal that attract the insects to pollinate it.
