Which statement is an inference based on the picture? the animal is ugly. the animal has hairless feet with sharp claws. the animal has prominent upper and lower incisor teeth. the animal likely has poor vision since its eyes are so small.

An inference is a conclusion reached on the basis of evidence and reasoning; because of this, then probably that.

Because the silvery mole rat has small eyes (and spends most of it's time underground), it can be inferred that its vision is poor. Therefore, "The animal likely has poor vision since its eyes are so small."

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
