1. The concentration of an undiluted sample is 26.4 mg/ml. To calculate that answer, the concentration of the diluted sample was multiplied by the dilution factor. Knowing that the dilution factor is 2, work backwards to determine the concentration of the DILUTED sample.

What is the unit used to describe cell solutions measured in a spectrophotometer?

Spectroscopy is based on the ability of compounds to specifically create certain wavelengths of light.

true or false

You are reading chlorophyll a samples in the spectrophotometer at 665 nm. Which of the following absorbance readings are considered to be inaccurate?

Ideally, a standard curve should be a curved line, not a straight line.

True

False

which of the following are common uses for a spectrophotometer in a biology lab? There may be more than one correct answer.

Light with a wavelength of 600 nm is used to read the absorbance of microbial cell cultures because cellular compounds (proteins, DNA, chromophores) absorb light at this wavelength and therefore do not interfere with the measurement.

True

False

The spectrophotometer output is in what units?

Carrots appear orange in color because they are reflecting what color of visible light?

Describe how filtrate is formed and what substances normally end up in filtrate (and what substances do not). This should include a description of the anatomy and physiology of the glomerus and the glomerular capsule and how they interact with each other.

Cancer/Viral Scenarios Worksheet: For each scenario, diagram and/or explain the activities of the cells involved including the self cell, Cytotoxic T cell, Natural Killer Cell and/or T helper cell along with any pertinent cytokines and proteins.

1. The Human Papilloma Virus has infected the cervical cells of a patient and the cancerous cells have stopped producing MHC. Diagram the immune system’s response to these changes in the cervical cells
2. The Herpes Simplex Virus has infected your patient’s mucosal cells of the genitals and those infected cells are actively replicating the virus
