How was bio paper 52
can someone give me point on what they wrote for the planning question i want to compare because i think in that they said to use the same apparatus
was time taken to be determined for color change?
or were color changes to be compared at 10 minutes
What did you all write for question 2 last part because all evidence was supporting the deer thing
Also what did you write for random sampling technique

well yh time was determined for colour change
well it was abt need for culling but fig. 2.3 showed no significant difference whether sheep or no sheep so there was no point of having sheep for decreasing deer
also fig 2.2 explained that deer needed to be decreased as they caused decrease in plants

well random number generator using phone and dividing the whole area into small study plots
