Final answer:
The answer key for the diffusion in agar cubes lab depends on the specific experiment, but it generally involves measuring the rate or extent of diffusion in agar cubes.
Step-by-step explanation:
The answer key for the diffusion in agar cubes lab would depend on the specific experiment and the variables that were tested. However, in general, the results of the lab would typically involve observing the diffusion of a substance in agar cubes and measuring the rate or extent of diffusion. This can be done by measuring the diameter of the zone of diffusion or the distance the substance has diffused. The answer key would provide the expected measurements or results for different substances or experimental conditions.
