3. What is the difference between a reflex and a reaction? DRAW AND LABEL A SIMPLE DIAGRAM to explain your answer. 4. Close your right eye, look at the cross with your left eye. The circle will disappear. EXPLAIN WHAT IS HAPPENING 5. In this lab we will be measuring 2 factors that affect the rate of photosynthesis they are A) temperature and light B) chlorophyll A and chlorophyll B C) wavelength and intensity D) DCPIP and NADPH E) glucose and sucrose
What is indicated by the arrow, and what is its function?
List two structures of the eye are directly involved in accommodation.
QUIZ 1 Quiz Bank: NOTE the number of the question you wish to substitute - DO NOT answer that question!
The Reaction Rate ve. Intensity graph -- The amount of energy falls off as the square of the distance from the source (= the inverse square law).
The Reaction Rate vs. wavelength graph might mimic (roughly) the absorption spectrum for chlorophylls a and b .
2 more graphs 1. reaction rate vs wavelength 2. reaction rate vs. intensity
A Reaction Rate versus distance graph would be an exponential curve. A Reaction Rate versus intensity should be linear. Figures
A. These take some time to get right.
B. Pay close attention to format.
C. There will need four for this assignment
2 raw data figures (absorbance vs. time)
2 reaction rate figures (reaction rate vs. parameters, I.e., wavelength and intensity)
Example of a proper graph... * Ensure that axes are properly labeled, with units specified, even if there are no units (AU=arbitraty units) * Do not connect the points on the graph with lines; draw a best-fit line through the data set. * The independent variable (the variable you manipulate) should always be on the X-axis and the dependent variable (the read out from the instrument) should be on the Y-axis. * Include a descriptive title that explains what kind of plot it is, the technique that was used, which substance was measured, and what instrument was used to measure it. * IMPORTANT: Titles should not include (or be) "Plot of...", "Graph of...", or "...over a range of data points." - Be concise, but complete. * Do not plot too many data sets on a single graph - make multiple graphs if required.
