The effect of quantum physics on biology on a cellular level

Lab #6: DNA Extraction You are going to use two online resources to extract DNA. One will be a virtual lab and one you will do in your own kitchen following the directions. Use the worksheet in the assignment resources to complete the lab write-up for the Part 2. Resources:  Virtual DNA Extraction How to Extract DNA from Anything Living!  Part 1: Virtual DNA Extraction Go to the above website and follow the instructions. Answer the questions below. Note: This part does not need to be in a “lab write-up format.” What are some reasons we extract DNA? Where is DNA found in the cell? What type of cells were collected from the test subject? What are the four steps of DNA purification? Explain what the ingredients in the lysis solution do.  What is the end result of the DNA extraction? Part 2: How to Extract DNA From Anything Living! (this part needs to follow the lab write-up format) Problem: What is the appearance of DNA when it is isolated from the rest of the cell? Hypothesis: write in an if…then…format Materials: list the materials you used Method: briefly summarize the steps you took in the lab Note: Place isopropyl alcohol into the freezer…it should work better! Results: (Make a sketch of the test tube with labels for each layer.) Discussion/Analysis: Why did we need to use the liquid soap? (hint: what does the soap do to the cell membranes?) Why did we add enzymes to the solution?  Try at least on other experiment with DNA extraction. What did you change? What was the result? DNA can be isolated from any cell in a manner similar to this. What could extracted DNA be used for? The DNA of all organisms contains the same four bases – adenine, thymine, guanine, and cytosine. What might this similarity indicate about the origins of life on Earth?  Conclusion: Answer the problem question.

7. Defend or refute this statement “Stem cell biotechnologically has the potential to produce revolutionary therapies for the treatment of some human diseases”. (Clearly explain biotechnological concepts and techniques, inclusive of legal and ethical constraints)

The critique must include the following points: You will be graded for each of these points.  I will pay particular attention to G) A) Brief introduction of the scientific process being investigated B) Objective of the Study-  What was the goal of the study? What question(s) did the author(s) ask?       What was their hypothesis? C) Key observations:  What were their most important findings? D) What techniques were used: Materials and Methods. E) How did this work help advance our understanding of the topic?  F) What is the conclusion? G) Your own perspective – were the data convincing? What other experiments would you have done?

What risk are associated with high cholesterol intake? The RDA for protein intake is 0.8 grams per 1 kilogram (kg) of body weight. Calculate body weight in kilograms then multiply that by 0.8 to obtain the recommended grams of protein Body weight is 160.

Fungi tend to reproduce sexually when nutrients are limited or other conditions are unfavorable, but they reproduce asexually in more ideal conditions. Why is this strategy successful?

Pick a region of the body (e.g., pectoral girdle, hand, neck, thigh, etc.) and prepare a written paper of at least 1000 words on the following bullet points: Describe the type(s) of muscle, patterns of fascicle organization, actions, and attachment points for the muscles present in your chosen region. Trace the pathways by which the presence of a sensory stimulus (e.g., a bug crawling across your skin) in your chosen region is processed and the subsequent motor behavior that carried out. Be sure to identify the initiation and termination points of the tracts, where the cell bodies of the neurons present in the pathway are located, along with locations of any synapses that occur along the tract. Focusing on one specific movement performed by muscles in your chosen region, identify the prime mover, synergists, and antagonists. Predict how a stroke in the primary somatosensory cortex would affect both the anatomy and function of your chosen region differently than a stroke in the primary motor cortex.

What other animal materials harvested or purchased by humans besides meat/blood may serve as viable transmission for zoonoses? That is my question.  I have already picked what I want to look into which is animal skin are viable transmission    I just can’t find scholarly articles from a database, I will need a database for the rationale in the introduction and the background. The methods part I have the section done. Provide articles for me to provide in my final.

Please separate them out under headings.

Review the major aspects of how the human immune system functions. How is the proper functioning of this system of major importance to all other systems in the body? What kinds of things can go wrong with the immune function and how do these problems interfere with human life?
