"VWR"

Often mistaken for beetles, these wingless crustaceans live their whole lives on land, feeding on decaying organic matter.

You will receive a sample of both green and brown hydra mixed together, allowing you to observe the differences between the two organisms.

These plasmids allow you to perform bacterial transformations, conferring new antibiotic resistance, as a visual way of demonstrating gene transfer.

These unique salamanders keep their gills and stay fully aquatic even into adulthood, making them ideal subjects for embryological and developmental studies.

This organism is commonly isolated from human nasopharyngeal mucosa

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

Feldspar group; pink cleavages showing perthitic texture, common potassium feldspar, Mohs’ hardness of 6.
