inferential questions

Question 1

suggest

why (incubate at) this temperature

INFERENTIAL QUESTIONS

Answer 1

optimum temperature for enzyme activity –> fastest rate of enzyme activity

Question 2

how to evaluate

a conclusion drawn from a graph

INFERENTIAL QUESTIONS

Answer 2

accurate: because it shows is being correct
inaccurate: because there were insufficient number of trials / experiments / test smaples

EVALUATE = BOTH SIDES

Question 3

how to account

for a change / difference in __

INFERENTIAL QUESTIONS

Answer 3

state what increased / decreased OR more / less
⭐⭐ focus on the change

e.g.
✅ rate of anaerobic respiration increased
❌ anaerobic respiration occurs

Question 4

state

what change in body size affects

INFERENTIAL QUESTIONS

Answer 4

change in surface area to volume ratio
a decrease in SA:V reduces heat loss

(also, if SA:V is higher, rate of respiration increases to help maintain internal body temperature since heat is lost quickly)

Question 5

explain

reasons for why you boil something

INFERENTIAL QUESTIONS

Answer 5

• denature enzymes / kill cell
• denatures membrane proteins in cell surface membrane causing it to break down + (and since the XX also gain kinetic energy) = more diffuse out of the cell
• remove unwanted gases (e.g. dissolved oxygen to create an anaerobic environment)

Question 6

explain

a reason why you wash something

INFERENTIAL QUESTIONS

Answer 6

remove excess XX on the surface

Question 7

explain

why you choose a certain (large) sample size

Answer 7

• ensures representative sampling
• a more reliable mean/average/percentage etc

do NOT just say “more reliable”

Question 8

explain

why carbon dioxide (from the body) must be removed

Answer 8

accumulation of CO2 lowers pH of blood which could denature enzymes
