Your undergraduate colleague accidentally mislabels tissue samples taken from different parts of a rat. In order to correct his mistake, you make slides from each sample and stain all tissue red and all nuclei blue. Upon analyzing one slide under a compound light microscope, you see many small reddish pink dots but no blue. This slide must be a sample of tissue from the rat's ___________. Select one: a. lungs b. thymus c. liver d. blood e. striated muscle

The body is organized in a particular manner and order. The cells identical in configuration and operation bind together to form a tissue. Different layers of comparable cells form tissue of the body which have a specific function in an organ.

The correct answer is:

Option D. blood.

This can be explained as:

The cells of the lungs, thymus, liver and striated muscles all have a nucleus that is why when stained will show a blue colour for the presence of nuclei.

The cells of blood or the red blood cells are the sole eukaryotic cells that do not contain nuclei in their developed form.

The blood cells expel the nuclei and other organelles from within so that it can transport more oxygen and haemoglobin.

Therefore, the slide in the experiment is of a blood sample.
