If an imaging sensor has more pixels, what happens to image resolution?

More pixels means greater image resolution. When a sensor has more pixels, it can sample the scene at finer intervals, capturing smaller details in the image. Think of each pixel as a tiny measure of light from a specific spot; increasing their number increases how finely you sample that scene, so you can distinguish finer features in mammography or any detailed image. Keep in mind that actual perceived sharpness also depends on the lens resolving power, pixel size, and how the image is processed and displayed. If the optics can’t resolve those fine details, adding more pixels won’t produce new information. Color depth, on the other hand, relates to how many bits are used to represent color per pixel and doesn’t change the amount of spatial detail.
