Catalase Lab Report

As the catalane and the substrate interact, the substrate is brought into the catalane and broken apart into water and oxygen. This process may be able to happen naturally, but the enzyme, catalane, speeds up the process. It does so by bringing a molecule into it’s active site and shifting it’s own shape to put…

A Better Understanding of Cephalopods

Asphodels are often regarded as he most intelligent of invertebrates as they posses large brains complemented by well-developed senses. The class developed during the late Cambrian, and early asphodels were likely predators near the top of the food chain. Their lengthy evolutionary history spans an impressive 500 million years and has left a vast record…

To pin the animal, we used etcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first incision had to locate the Oxford Process of the rat (distal aspect of the sternum). Once I had located the Oxford Process, I had to use…

Lab Report

Daphnia, or Daphnia magna, are microscopic organisms in which the students created an original lab to test the reactions. These organisms come from the group daphnia, which is also a part of the Clearer, a group related to freshwater shrimp. Daphnia acquired is common name due to the erratic movements. Daphnia are small crustaceans that…

Lab Report

Pure bending refers to flexure of a beam under a constant bending moment. Therefore, pure bending occurs only in regions of a beam where the shear force is zero ( because V = dim/DXL ). In contrast, uniform bending refers to flexure in the presence of shear forces, which means that the bending moment changes…
