What phase of the neuron is represented in the diagram? 

Study the diagram.   Identify the main cell type involved in antibody-mediated immunity.

Describe what happens to the field of view as you increase magnification.

 Which type of channel is responsible for the repolarization of the neuron indicated by the yellow box?

Select all of the standard lab safety protocols.

Study the chart and then answer the following question.   Which of the following would most appropriately be placed in the “A” box?

How is total magnification determined?

 Which letter corresponds to the conducting region of the neuron?

Explain the difference between magnification and resolution.

A student was investigating factors that influence enzyme reactions.  In the experiment, they used an enzyme called catalase which catalyzes the breakdown of H2O2  (hydrogen peroxide) into H2O (water) and O2 (oxygen gas).  In each of the tubes, they put a different amount of catalase.   Tube 1 – no catalase + 5ml hydrogen peroxide Tube 2 – 1ml catalase + 5ml hydrogen peroxide Tube 3 – 2ml catalase + 5ml hydrogen peroxide Then the student recorded the following results: TUBE Volume of Bubbles Observations 1 0ml No bubbles visible 2 5ml Bubbles are white, frothy and about halfway up the tube 3 9ml Bubbles are white, frothy and almost to the top of the tube   Which column in the student’s data chart represents quantitative data?
