Directions: In this module, you learned about body size and temperature regulation strategies. Scientists have argued for many years about whether dinosaurs were warm- or cold-blooded, with most recent findings supporting warm-blooded. Compare what you know about the Earth’s temperatures now versus then (65 million years ago) and to the […]

Lab – Spectrophotometry for the qualitative and quantitative measurement of biochemical compounds OBJECTIVES: At the conclusion of this unit the student will be expected to: Apply the principles of spectrophotometry to the qualitative and quantitative measurement of biochemical compounds. LABORATORY SEQUENCE: 1. Pre-lab discussion on the program for the session […]

Each wavelength corresponds to a different (spectral) color; thus, there are an infinite number of colors between 400 nm and 700 nm, our visual range. Furthermore, most objects have colors which are mixtures of different spectral colors – for example, purple results from a mixture of red and blue light. […]

You have a rabbit with an unknown illness. Apply Koch’s postulates to prove that a specific bacterial species is responsible for the rabbit’s illness. Identify all four postulates in your answer and describe how you would set up experiments to specifically address each postulate. – List and describe 2 distinguishing […]
