The yeast I use to make bread doubles in size overnight, but I take a fixed weight away each day.Which one of the following plots could not show the weight of yeast on consecutive days after the ixed weight has been removed?
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
Option B is the correct answer because it exhibits an inconsistent pattern not compatible with the systematic doubling and subtraction process described. For a plot to be incorrect, it must represent a pattern that is impossible given the scenario. Options A, C, and D could potentially depict the yeast's weight changes over time, as they can illustrate a regular pattern of growth (doubling) and reduction (fixed weight removal). Option A shows a consistent decrease, Option C depicts a steady pattern, and Option D aligns with the expected growth and reduction cycle.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.

A cleaning solution is used to remove limescale, CaCO3, from bathroom surfaces. When the solution is sprayed onto the limescale, effervescence (fizzing) occurs and the solid limescale begins to disappear. This chemical reaction is needed because the limescale cannot be removed with water alone. Which of the following statements about this chemical reaction are correct? 1. The cleaning solution is acidic. 2. The effervescence (fizzing) is caused by the release of hydrogen gas. 3. The pH of the reacting solution will go down as the reaction proceeds. 4. The salt produced in the reaction is more soluble than CaCO3
