A microbiology student with a visual disability is viewing a sample of Bacillus endospores in a phase contrast microscope that is linked to an iPad.By "stretching" the image on the iPad screen, the student can increase the apparent size of the endospores.How does this manipulation affect resolution and contrast? (No software is being used to alter the image!)

Question

Stretching the image on the iPad screen only increases the apparent size of the endospores, which is equivalent to increasing the magnification. However, it does not alter the resolution or contrast of the image, as these are fixed properties of the microscope and the sample being observed. Therefore, choice A is the correct answer.
