Use this template to sketch your predictions: Gel Template.jpg

Example of a gel: GMO PCR Data for report.png

Experimental Design must include:

  • Identify the independent variable and dependent variable in this experiment. (2 points)
  • Choose a food of interest and write an acting hypothesis for this experiment. (2 points)
    • This hypothesis should include the predicted cause and effect (the if ___, then _____) as well as the reason for that prediction (because ________). A hypothesis can be multiple sentences and does not need to follow the “if-then-because” format so long as it communicates the necessary information. See tips on hypothesis writing here: Hypothesis-Writing Resources.docx
  • Annotated gel figure with description (4 points)
    • Label each lane with its contents. Each of these should be depicted in a lane:
      • standard ladder
      • positive GMO control
      • negative GMO control
      • positive Plant control
      • negative Plant control
      • your prediction for the experimental food with GMO primer and with Plant primer

Discussion Points (3 points each):

    1. Explain the purpose of the standard ladder in gel electrophoresis.
    2. Explain the purpose of positive and negative controls. Why do we use both?
    3. Why would we use two different primers in this experiment? Can we trust a result from a test using only one sample amplified with the GMO primers (as opposed to two samples, one amplified with GMO primers and one amplified with Plant primers)?
    4. This experiment is extremely similar to COVID-19 PCR tests. What is the difference between this GMO PCR test and the COVID-19 PCR test? (Cite outside sources if needed)

*For all discussion points, use the data to support your conclusions. One-sentence answers will not be considered a discussion and will not receive full credit.*

Presence of Arsenic in Montezuma Well Essay

/in /by

I need help with a Chemistry question. All explanations and answers will be used to help me learn.

Canned Research Project – Arsenic Project – abstract (150 =/+ words), results, discussion, and conclusion (700 =/+ words, excluding data & text in tables, figures, titles, and captions)

Write a non-full lab report based on the provided canned research project. Posted are the 3 documents: (1) a PDF, filename: “Arsenic Project;” (2) an Excel spreadsheet, filename: “Arsenic Data” and (3) my draft document filename “84” with comments in BLUE

The final report will include the following sections: abstract, results, discussion, and conclusion. Write the report as if submitting it to a peer-reviewed journal following the iterative style.

1. References: Support the discussion (interpretation of the results) with scientific literature references. The canned research project provides five (5) references. When writing your R & D, use a minimum of three (3) references in writing this non-full report; one of these three must be a reference you found in this Project pdf; the other two I have provided in the attachment (Johnson2012 & ZK article).

2. Audience: Write the report for a scientific audience (e.g., readers knowledgeable in a specific area of science).

3. Results & Discussion: (1) write these in the iterative style, (2) the results in an appropriate format (text and at least one graphic, e.g., a table or a figure but no more than three graphics), (3) align left paragraph spacing.

4. Conclusion: This should be a separate section. 5. Abstract: (1) justify paragraph spacing, (2) write this section last

Biology and Thermodynamics Questions

/in /by

I’m studying for my Biology class and don’t understand how to answer this. Can you help me study?

 

  1. The second law of thermodynamics says that energy transformations result in the universe becoming more disordered. If this is the case, how do we account for biological order?
  2. Describe the two types of chemical reactions and provide an example of each type of reaction as it occurs in living cells.
  3. How are chemical work, transport work, and mechanical work powered by ATP?
  4. What do enzymes have to do with chemical reactions?
  5. Explain how the unifying theme of “interactions between components of a system” relates to the cellular control of enzyme activity.
  6. How is energy harvested through cellular respiration?
  7. How is the transfer of electrons involved when your cells extract energy from fuel molecules?
  8. Outline and describe each step in glycolysis in a way that helps you understand the overall process.
  9. Outline and describe each step in the citric acid cycle in a way that helps you understand the overall process.
  10. What is the estimated number of ATP molecules produced from a single molecule of glucose? How many from each process in cellular respiration?
  11. What are autotrophs and why are they significant?
  12. Explain (in writing…using you own words) what is being diagrammed in Figure 7.2 starting with the picture of the leaf and ending with the picture of the thylakoid. Demonstrate your understanding by using the bold terms from section 7.2 in your description.
  13. What do light reactions and the Calvin cycle have to do with photosynthesis?
  14. What three components involved in the light reactions are imbedded in the thylakoid membrane?
  15. How is the energy created by the light reactions used to reduce CO2 to sugar?
  16. Explain some ways in which photosynthesis is globally significant.

American Commercial College of Texas Hydrogeology Slug Tests Lab Report

/in /by

I’m trying to study for my Geology course and I need some help to understand this question.

 

During lab we conducted slug tests on wells located at Miles Crossing near Ramsay. For this lab you will need to use the data from the well you tested and determine the hydraulic conductivity of the aquifer surrounding the well.

  1. Labs must have names! Labs without names will be deducted 2 points (If you chose a digit submission via Moodle, make sure you name in both in the actual document and in the document submission name)
  2. Include all graphs and/or data tables you make.
  3. Include symbolically represented equations and define your variables. Please label each equation.
  4. You do not need to include a calculation for every iterative process. However, you should have at least one sample calculation for each equation you use.
  5. This is a very calculation heavy lab assignment so please be neat/organized. Use as much scrap paper as you need (the trees will forgive you, I promise).

everything is attached.

Mitosis Data and Calculations Biology Lab Worksheet

/in /by

I’m studying for my Biology class and don’t understand how to answer this. Can you help me study?

 

Mitosis Worksheet

For each stage of mitosis, label the stage with the name,draw the configuration of two sets of chromosomes and spindle fibers, then below your drawing list the things that happen for the stage. You can work with other students in the class, but you must do your own drawing. When you are done, upload the drawing for your instructor to check.

Table 1: Mitosis Data and Calculations

 

  Interphase Prophase Metaphase Anaphase Telophase
Number of cells in stage

 

          
Mitotic Index =

# Cells Dividing /

Total # cells Observed

          

Questions:

Which phase of mitosis has the longest duration in this organism? How do you know?

 

Which of the phases of mitosis has the shortest duration in this organism? How do you know?

Which phase is longer overall, mitosis or interphase? How do you know?

If you were to assume that the total cell cycle time for these cells was 16 hours, use the information in your table to determine how much time would be spent in each of the 5 phases (interphase, prophase, metaphase, anaphase & telophase).
