Final answer:
Yasmeen, searching for keys under the bed in a dim environment, is likely to have the most rods activated in her retina as rods are more active in low light conditions, contrary to cones which are active in bright light.
Step-by-step explanation:
The question seeks to determine who among the given individuals is likely to have the most rods activated in their retina. Rods are light-sensitive photoreceptors in the retina that are particularly sensitive to dim light, important for peripheral vision, and do not allow for color vision, but enable the detection of shades of gray. Considering the scenarios described:
- Blake is reading a book while sunbathing, so the intensity of the light is high, and cones would be more active.
- Yasmeen is searching for her keys under the bed in a likely dim environment, which suggests greater rod activation.
- Gavin is painting a mural during the day, in what can be presumed to be a well-lit environment, thus relying more on cone activity.
- Dale is working on a detailed pen and ink drawing which doesn't specify the lighting condition, but could be done in a well-lit environment for precision.
Based on this information, Yasmeen, who is searching for her keys under the bed in a low-light environment, is likely to have the most rods activated in her retina.
