Controversy and controversial Science. Based on what you have read so far, please describe the difference between a “scientific controversy” and “controversial science”? Choose an example and describe where the controversy comes in and where the science comes in. For example, does most of the uproar come from inside or outside the scientific community? Are scientists generally in agreement about the general underlying knowledge or behavior of the people involved in generating that knowledge? How does all of this relate to the social side of science, or to the relationship between science and society?

A sample solution containing lipids. Started my lab but don’t understand what would be the proper way to the conclusion as many of my hypotheses were wrong. As well how to properly answer the questions
Part 2: Testing for Lipids
Background Information:
Lipids are a class of molecules that are not soluble (do not dissolve) in water. They are composed of molecular building blocks of glycerol and three fatty acids. Fatty acids come in two major types, saturated and unsaturated. This difference is due to the presence of particular types of bonds within the fatty acid molecule and affects the shape and characteristics of the overall lipid-containing these fatty acids. Today we will be performing the Paper Test to identify the presence of lipids. The paper turns translucent (gets a grease spot) in presence of lipids.
Question: Which sample solution will contain lipids?
Hypothesis: Hypothesize what will be which solution will have lipids present in the sample (no lipids, some lipids, etc), if any, for each solution. Record your prediction in Table 2 below.
Materials:
Distilled water
Vegetable oil
Hand cream diluted in water
Shampoo diluted in water
Brown paper bag
4 Disposable pipets
Timer
Paper and Pencil
Procedure:
Draw four circles in a brown paper bag and label them: Water, Oil, Cream, and Shampoo.
Put two drops of each corresponding substance on a brown paper bag.
Put the bag off to the side and let it sit for 15 minutes.
Record the appearance of the bag where you placed the spots in Table 2.
Results: (Watch the Lab 4. Chemical Composition of Cells video)

Conclusion:
What are the monomers for lipids?
Which type of lipids should we try to avoid eating: saturated or unsaturated? Explain.
Which samples were your positive and negative controls?
What happens when you mix oil and water? How does this relate to the phospholipid bilayer?
What types of gene or protein families may be important for multicellularity? Can we compare the genomes of different multicellular lineages like animals and plants to identify the most important genes critical for multicellularity? Why or why not?
10) As we have discussed in the lecture, homeotic genes specify the segmental identity and all encode the DNA binding motif called a homeodomain. In “Endless Forms Most Beautiful” Sean Carroll highlights other master regulatory genes like Pax6, Distal-less, and Tinman that regulate eye, appendage, and heart development respectively. Each of these genes also encodes the homeodomain DNA binding motif. 1) How do the homeodomain amino acid sequences compare amongst these different types of master regulators? 2) What does this suggest about how these master regulators work? 3) How can genes that encode the same type of motif, a homeodomain, direct the development of such different structures? Briefly address these three questions based on your reading of “Endless Forms Most Beautiful”.
11) Animal design is modular and composed of repeating units that vary in number and kind. Provide an example(s) that highlights the underlined concepts from the first sentence and briefly make the connection between each concept term and the example.

Analyze these drinks to see which substances they are comprised of each have different amounts of carbohydrates ( sugars), electrolytes, and flavor. What roles does carbohydrates play in each of these sports and what is the best combination for a particular sport ? Which drink is best for an athlete’s performance and why ?

Discuss the parameters of your major and the types of jobs typically associated with it. Use the Kean University Online Library Research Guide for your major or intended field to help you find resources that will allow you to discuss the types of jobs your major could offer, the history of the major or field, and what you will need to accomplish in college to be successful in that career (does your potential career require certain degrees, experiences, grades, etc.?), and anything else you feel is particularly important for someone interested in your potential career to know.

Deoxyribonucleic acid in enzyme restriction. How often would a restriction enzyme such as Not I, which has 8 nucleotides in its recognition sites 5′-GCGGCCGC-3′, cleave DNA on average?
Would it cleave a species’ DNA more or less often if the DNA from that species were 70% A-T rich?
