Read Behavioural Assays
A focused NSEB read for the behavioural assays pattern. Learn the linked concept, then apply it in the source questions.
Living-system questions are solved by matching a structure or organism to its function, process and stated condition.
Behavioural Assays
Escape activity serves as an experimental response. Greater immobilization means the animal spends less time attempting escape. HFD animals show greater immobilization than controls, consistent with reduced agility/escape effort (C). Lithium-treated animals show lower immobilization, indicating improved persistence in escape/stress-coping behaviour (D). The graph alone does not demonstrate brain toxicity or simply greater energy availability as causal explanations.
Compare choice across conditions
Read the response before explaining it: the response is the percentage of young bees in each temperature zone after 30 minutes. The 36°C panel has the highest medians at every group size, so it is the preferred zone. At larger group sizes, more bees occupy the cooler zones, consistent with crowding. Choose B and D; do not call the group-size differences absent or reverse their direction.

- ✓Compare medians across all conditions before inferring preference or crowding.
Read the conditions in the stem carefully and use the stated model, labels, or assumptions before choosing an answer.
