Answer :
Final answer:
An experimental investigation testing groups of yeast at different temperatures is the best approach to gather evidence regarding yeast growth rates in relation to temperature.
Explanation:
An experimental investigation testing groups of yeast by exposing them to different temperatures for equal amounts of time and then measuring their growth rates would be the most suitable investigation to gather evidence to support or refute the claim that yeast cells grow more rapidly at higher temperatures. By exposing yeast to varying temperatures and measuring growth rates, the scientist can analyze the effect of temperature on yeast growth.
