Question Approach

Question 1

When given a graph and asked to describe the effect of…
What key words must you use?

Answer 1

• Increase in X led to a rapid increase in Y
• Increase in X resulted in a rapid increase in Y
• Increase in X caused a rapid increase in Y

Question 2

When drawing a line to determine whether an increase or decrease is rapid or gradual, the curve falling below the line implies?

Answer 2

Gradual

(Above the line implies rapid)

Question 3

Steep lines in graphs imply?

Answer 3

Rapid

(Less steep imply gradual)

Question 4

When asked to explain the effect of X on Y in graphwork, how would you answer?

Answer 4

• Start with effect
  Eg Far red light led to (caused, resulted in) inhibition of flowering in long day plants
• Explain why
  This is because…

Question 5

When given a question with commas, how does one approach it?

Answer 5

Account for each part of the question divided by the commas

Question 6

When given 3 things to compare on a graph, which word would you use for the similarities?

Answer 6

All (not both)

Question 7

When differentiating in graph work what are some of the key differences to look out for?

Answer 7

• Which is generally higher, lower
• Which is initially higher, lower
• Which attains a maximum/ peak earlier
• Which attains a higher maximum/peak
• Increase, decrease
• Gradual, rapid

Question 8

What is the difference between a maximum and a peak?

Answer 8

Peak- You rise and come back down like a mountain peak
Maximum- No return, you go up but don’t come down

Question 9

When given a graph number in paper 2, what should you do first?

Answer 9

Read the question carefully and underline where necessary

Question 10

When asked to describe the variation of two variables in a graph number, how do you approach it?

Answer 10

Describe each separately

Question 11

What words should you use when a graph question is given asking for the relationship between two variables eg A and B?

Answer 11

• As A increases, B decreases
• Both A and B increase
• A increases whereas/ while B…

Question 12

What do you associate temperature with?

Answer 12

• Enzyme action
• Kinetic energy (Rate of diffusion, cooling of the skin etc)

Question 13

What do you associate the globular structure of proteins with?

Answer 13

Solubility

Question 14

When asked to differentiate between x and y, what must you avoid?

Answer 14

• X has while Y doesn’t have
  (Be specific and state what each has that are different from each other)
