Auxanographic method
a method for the study of bacterial enzymes in which agar is mixed with the material (e.g., starch or milk) which is to serve as an indicator of the enzyme action and is inoculated and plated; if the bacteria produce enzymes digesting the admixed material, there will be a zone of clearing in the medium about each colony.
Synonym: diffusion method.
Organisms employ different strategies to boost its defenses against antigens. Humans have an immune system to combat pathogens. Read this tutorial to learn the first and second lines of defense that the human body employs. ..
This tutorial deals with the structure and function of flowers, fruits, and seeds. Also included here are the types of fruits, fruit dispersal mechanisms, and seed germination. The distinctions between dicots and monocots, the two major groups of flowering plants, are presented in this tutorial...
Multicellular organisms evolved. The first ones were likely in the form of sponges. Multicellularity led to the evolution of cell specializations that form tissues. Another major event was the evolution of sexual reproduction. The emergence of sex cells in the timeline provided a means for organisms to further diversify. Know more about these crucial events in geologic time in this tutorial...
The arthropods were assumed to be the first taxon of species to possess jointed limbs and exoskeleton, exhibit more advanced receptors in the form of eyes, and develop various chemoreceptors. Since they possess such desirable features, their survival over the long term is apparent by their genetic diversity. Learn more elaborate details about arthropod evolution in this tutorial...
