EPSP and IPSP calculation

The membrane potential, Em, of a post-synaptic cell can be calculated from the following equation:

 

equation in attachment

 

 

where grest is the leakage current which maintains the resting potential, Erest is the normal resting potential, gE is the conductance due to excitatory post-synaptic channels (e.g., AMPA channels), ErevE is the reversal potential for the excitatory channels, gI is the conductance due to inhibitory post-synaptic channels (e.g., GABA channels) and ErevI is the reversal potential for the inhibitory channels (this equation comes from the equivalence circuit discussed in Lecture 13 & 14, slide 21). Assume grest = 1 milliSiemens, Erest = -65 mV, ErevE = -10 mV, ErevI = -70 mV.

a) If gE at the peak of the EPSP is 2 milliSiemens, what is the height of the EPSP without an IPSP (i.e., what is the change in potential from resting)?

b) If gI at the peak of the IPSP is 1 milliSiemens, what is the change in potential from resting?

c) What is the sum of the peak IPSP voltage change and the peak EPSP voltage change?

d) What is the net change in synaptic potential when an EPSP and IPSP occur simultaneously? Why is your answer different from the simple sum of potentials in part c?

Experiment Mitosis

Experiment  Mitosis
Lab RepoRt assistant
This document is not meant to be a substitute for a formal laboratory report. The Lab Report
Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables
that should be addressed in a formal lab report. The intent is to facilitate student’s writing of lab
reports by providing this information in an editable file which can be sent to an instructor

Mitosis Worksheet – Answer the questions about the photos below:
Onion root tip photos at 600X and 1000X taken by Stan Carpenter of Hands-On Labs, Inc.

1. What phase is this cell undergoing?

1. The two center side-by-side cells are
undergoing two different phases of
mitosis.
a. What are these phases?

2. What happens after this phase?

b. What diagnostic features can help
you with your decision?

1. What phase is this cell undergoing?

1. This cell has clearly visible chromatids.
a. What’s the next phase this cell will
undergo?

2. How can you tell?

b. Where will the chromatids go in the
coming phase?

1. The cell in the lower center is exhibiting signs 1. Explain what happens during anaphase.
of what phase of mitosis?

2. What phase does it appear the cell above is
2. When the chromatids separate, what is
undergoing?
each called?

Questions
A. What is the purpose of mitosis?

B. Why is the cell cycle important for organisms?

C. What role does mitosis play in the growth of an embryo?

D. What is one main difference in the mitotic processes between plant and animal cells?

E. If the cell that has undergone mitosis originally had the diploid (2n) number of chromosomes,
then what number of chromosomes will the nuclei in the two new cells have?

F. Can mitosis ever be used for reproduction?

G. What parts of plants are most impacted by mitosis?

H. Why might mitosis be easier to study in the tip of the root?

I. Where else in a plant might you find a large amount of mitotic cell division occurring?

J. How might the mitotic index be applied in agriculture?

K. What did you compute to be the mitotic index of the combined six slides (assume there are
54 total cells)? In comparison to the indexes reflected in Figure 8, from approximately which area
of a root was the sample taken?

Biology Discussion 1&2

You must have atleast 4 meaningful sentences in the discussion.  Discussion must be in Microsoft Word and must be an original answer no plagiarism. Primary postings should include either a concise summary of information from the textbook or an analysis of the topic under study.  Please don’t use long quotations.  Please note within the text of your discussion posting where you got your information.  Outside research should be academic in nature and come from reputable peer reviewed sources.  You must include your references with your posting cited in APA style.  Answer each discussion seperately.

Discussion 1

The characteristiscs of life are considered to apply to all forms of life but they are not always easy to recognize.  Which characteristics of life do you feel is most difficult to apply to a plant and why?

Discussion 2

Water is considered to be a requirement for life.  This is a nice sounding statement but if it is true we should experience and benefit from all the properties of water daily, but do we?  What are your daily and routine experiences with water that demonstrate water is truly important for our existence

Discussion section of Research paper

Analyze and Interpret the results of the study.

Explain why you believe the hypothesis (tobacco will interact with DNA and cause genetic changes that will affect the lungs, also lung cancer will appear because gene-carcinogens will be activated) matches the results (gene carcinogens from tobacco will affect DNA and then cause lung cancer)

Explain why the number of lung cancer deaths have been increasing in the US, according to the table shown.

Explain why heavy smokers were found to be at greater risk of developing lung cancer.

Also, explain why there is a great relationship between smoking and lung cancer

Finally explain why children born by smoking mothers were also found at risk of contracting lung cancer
