Conduct this experiment the shell must be removed. To remove the shell place the two eggs in a jar of vinegar large enough to cover the two eggs with the liquid. Allow standing for three days. Because the inner semipermeable membrane is fragile, take care not to puncture or tear the membrane when moving the eggs.

Place each egg in a clear glass. Cover the first egg in water. Cover the second egg in corn syrup. Allow the eggs to sit in the solutions for 8 hours.

  1. What is your null hypothesis?
  2. What is your alternative hypothesis?
  3. Explain your alternative hypothesis.

  5. Measure each egg and record the results.
  6. Explain the results.
  7. Which egg shows the greatest change? Why?
  8. Now reverse the process. Place the egg that was originally in the water into a glass with corn syrup and place the egg that was in the corn syrup into a glass with water. Let stand for 8 hours. Measure each egg and record the results.
  9. Using key terms from this lesson, describe your results
  10. Which egg shows the greatest change?

What animal do you expect to see the most of during the course of the first week of the block? Identify the independent/dependent variables of your study.

Recording observations and background research

Use animals touch as birds and lizards. Say that you expect seeing lizards most in your observation this week. You can also list other animals that live in Florida and would be around campus.

Recording Observations and Background Research

Lab 1: Students are introduced to the initial processes involved in the scientific method, which includes making observations, collecting preliminary data, and performing background research.

Objective:

To understand the importance of recording observations and good data collection along with performing background research prior to making any substantive hypothesis

Materials

Log (spreadsheet)

Computer/iPad with internet access

Part A: Research Question and Hypothesis

  1. Begin with a research question: What animal do you expect to see the most of during the course of the first week of the block?
  2. The “answer” to this question forms the basis of your hypothesis. This is what will be tested in your experiment.
  3. Identify the independent/dependent variables of your study.

Part B: Lab Assignment, Recording Observations

  1. For the next five days, log every animal you see on and off campus in an Excel workbook. Be sure to indicate the location. If you spend all of your time on campus, you will not have any “off-campus” observations.
  2. Only use basic terminology to describe what animal you saw. If you don’t know the species, just write the generic term — i.e. if you see a white bird and you don’t know if it is an ibis or a heron, just write “bird”
  3. Upload this document to the Canvas assignment portal when you are finished.

Concentration of Reb.

You discover a plant species in South America used by local populations that contains a chemical compound in its leaves that tastes sweet but does not contain calories (the chemical is abbreviated Reb. A.) You immediately think of selling this artificial sweetener in the USA and earning tons of money. The problem is that the concentration of Reb. A is very low in the leaves of the wild population of this plant and therefore expensive to grow, purify, and sell. You decide to breed a population of these plants with super-concentrated Reb. A.

You have plenty of land, greenhouses etc… Explain how you would breed a population of plants with super-concentrated Reb. A. Your initial population was collected from the wild and has an average concentration of 0.02g Reb. A/ g leaves. (Assume you have the ability to easily check for Reb.A concentration). In your explanation, clearly connect what you are doing with your population to Darwin’s four postulates we discussed in class.

(There is no need to use any information beyond what we discussed in class.)

 

History of Evolutionary Thought

Summarize the Idea/Person assigned to you and connect that Idea/Person to two other Ideas/People presented in class. Your response should place your idea/person in the context of the history of evolutionary thought. Discuss how the other ideas influenced your idea, or how your idea influenced the other ideas.

In your answer, start with a paragraph summarizing the Idea assigned to you (You might need to change the first and last sentence to create a cohesive response.) Include additional paragraphs addressing the connections as prompted above.

Branched-chain amino acids

The paper will consist of 4 single-spaced pages on branched-chain amino acids (BCAAs). The cover page and reference list will not count toward the length requirement. The paper will contain an introduction, body and conclusion.

The introduction will provide a brief outline of the ergogenic aid.

In the body you will discuss the pathophysiology of the ergogenic aid as well as the benefits and any possible side effects.

The paper will cover research conducted on the ergogenic aid and results of those studies will be discussed.

Using Ergogenic Aids as an Adjunct to Proper Training and Diet

It goes without saying that any ergogenic effect you experience from taking a supplement or drug is not going to make up for a poor diet or lack of training consistency. If you want to increase muscle mass, get stronger, and cut body fat, you need to eat properly and push yourself in the gym. Nothing will turn you into a professional-level athlete without those pillars in place.
