Taste test control strips, tasteless
Taste test control strips without flavor are neutral test papers used as a reference in taste tests. The strips make it possible to compare the experience of control paper with PTC test paper, which contains a bitter flavoring. This allows test subjects to more clearly assess the difference between no taste and a possible bitter taste.

Testicle, cross-section, microscope slide
This microslide shows a cross-section of testicular tissue, showing the cells and structures involved in sperm formation. The slide is stained with red and blue contrast dyes, making it easier to distinguish the different cell types and tissue layers. The nuclei of the cells appear as darker structures, while the cytoplasm and cell membranes form the surrounding shapes. The slide is designed to closely resemble illustrations in biology textbooks, making it easy to recognize the most important details, even without a medical background.
