Worked Solution & Example Answer:Bees are flying insects that feed on nectar made in flowers - AQA - A-Level Biology - Question 3 - 2018 - Paper 1
Step 1
Step 2
Step 3
From the data in Figure 4, a student made the following conclusions. b. The town is the least favourable for bees.
Answer
The town shows a peak in species richness later in the year compared to natural and farmland habitats and has the lowest mean number of bees, indicating it is the least favourable environment for bees.
Step 4
Step 5
The scientists collected bees using a method that was ethical and allowed them to identify accurately the species to which each belonged. 2. allowed them to identify accurately the species to which each belonged.
Answer
The method should facilitate close examination of bees, possibly using identification keys or photographic documentation to ensure accurate species identification.
Step 6
Suggest and explain two ways in which the scientists could have improved the method used for data collection in this investigation. 1.
Answer
The scientists could collect data more frequently throughout the year to observe variations in bee populations effectively. This could provide better insights into trends over time.
Step 7
Suggest and explain two ways in which the scientists could have improved the method used for data collection in this investigation. 2.
Answer
They could survey a greater number of sites within each habitat, which would enhance the representativeness of their data and improve the accuracy of their findings.
Step 8
What do these names suggest about the evolutionary relationships between these bee species? Explain your answer.
Answer
The inclusion of 'Andrena' in two of the species names suggests that Peponapis pruinosa and Andrena chlorogaster are more closely related to each other than to Andrena piper. This indicates they share a more recent common ancestor, highlighting the evolutionary relationships among these bee species.
