Alife science student uses a compound microscope to look at a slide of human tissue. he is not sure what part of the body the tissue is from, but makes an educated guess based on the cells he sees on the slide. there are hundreds of round disks with no nucleus, as well as a couple of purple-colored spherical cells. the student would most likely guess that the tissue is of: (a) bone(b) tymus(c) blood(d) muscle(e) lung

C

Explanation:

Blood contains red blood cells (erythrocytes) that do not contain nuclei and are biconcave to allow them to carry more oxygen for diffusion. Therefore the round disks with no nuclei are red blood cells.

The purple-colored spherical cells are probably blood platelets if they are small or they could be white blood cells (lymphocytes) if they are larger.
