Explain the development of a drug or protein.
Name the three R's of the ethical framework
Reduction: the use of as less animals as needed, or do more tests on one animal > produces low statistical power.
Refinement: makes it pleasant for the animal. This makes trustworthy outcomes.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are the three types of validity?
Predictive validity: animal predicts the way the compound will effect humans
Construct validity: the same biological processes are involved, you can test this with neurochemistry, anatomy, molecular pathways and genes

3. a GM mouse is born and its cognitive abilities are tested: through primary (observation), secondary (motor and sensory functions) and tertiary (specific behaviour) screening.
