Directions Open the link to the document to find the experimental procedure and instructions for extracting DNA from a banana. Once completed, you will submit a photograph of your final result, along with the answers to several questions included in the file. Follow the detailed directions below: First, read the full instructions in the document, Isolating DNA From a Banana.docx (????????). Gather your supplies, most of which you may have at home already, others of which are readily available at local grocery stores or pharmacies. Collect the DNA. Take a photograph and answer the questions in the document. Save the document in .doc or .docx format. Name it as "Mod3-Activity-Your Initials." Hands-on Activity Grading Rubric Question 1 (7 points for each reagent)Describe the purpose for each of the following reagents (ingredients) in your experiment. In other words, why are these necessary in the DNA extraction process? Please use complete and descriptive sentences when formulating your answers. Banana, Salt, Dish Detergent, Isopropyl Alcohol A picture of your completed experiment
Description Identify an environmental issue facing your community. (Air Pollution in California). Imagine that you have been asked to educate the members of your community on this environmental issue. Create a 12- to 14-Microsoft® PowerPoint® slide presentation about your selected environmental issue. Include the following in your presentation: An overview of your selected issue. The effects of human activities on your community and the biosphere and how this has led to your chosen issue. The biotic and abiotic environmental components involved in this issue and how their interaction has affected the diversity of organisms in your environment. How energy and materials flow in your local ecosystem and how this is related to your selected issue. Some actions those in your community can take to diminish the issue
Description Question 1. Watch this video Links to an external site. Do you think we are living during the 6th mass extinction? Answer this question and in your answer, include your reasoning. It is perfectly ok to be undecided and choose the "I don't know" stance; however, you still need to discuss scientific reasons why you are undecided. https://www.youtube.com/watch?v=AKbJqNhadqU Links to an external site. Questions 2. Create a phylogeny for jellybeans A through E and the ancestor using their characteristics (color and flavor) listed below. Include the "trait table" and "number of changes" matrix. Remember to make one column for each trait in the character table. For example, if a jelly bean tastes like coconut and milk, make one column for coconut and another column for milk. A: white, tastes like cream soda B: white, tastes like coconut C: yellow, tastes like coconut and milk D: orange, tastes like tangerine and milk E: yellow, tastes like lemon Ancestor jelly bean: orange, tastes like raspberries and milk Question 3. Multiple choice question: Examine the figure below. Which of the following clade(s) is (are) consistently found in all phylogenies? a. AF b. CE c. Neither AF nor CE d. Both AF and CE. Question 4. Multiple choice question: You visited an island on which you found many closely related species of mice that form unresolved clade during phylogenetic reconstruction. After further studying these species, you concluded that they evolved in the absence of geographical barriers. Which of these statements falsely represent this scenario? a. this is an example of allopatric speciation b. this is an example of sympatric speciation c. this is an example of adaptive radiation d. this is an example of either adaptive radiation or sympatric speciation but not allopatric speciation (PLEASE MAKE SURE NOT TO PLAGIARIZE OR USE CHAT GPT!!!!)
Description Hello this is a very important biology lab needed to be done well. I will attach the slides you'll need as well as a youtube you'll need to watch to complete the lab successfully. I also have a low grade grade in this subject so its very important to go over your ork so it can be well and precise. Thank you so much!!
Description Go through the HHMI Biointeractive on Virus Explorer (Links to an external site.) and complete the accompanying worksheet Virus are considered to be obligate intracellular parasites, they consists of nucleic acid (DNA or RNA) and a protein coat. Some viruses (enveloped) have an additional lipid layer that which is derived from the host plasma membrane with modified viral specific proteins (spikes). Launch the interactive and explore the viruses in this activity.
Description Searching and Evaluating Scientific and/or Mathematical/Analytical Resources This week, you will find three scholarly, peer-reviewed research articles on your topic. Remember that next week you will submit a paper on Scientific and/or Mathematical/Analytical perspectives of inquiry, so use this week’s assignment to prepare materials and collect information for that purpose. Use articles that will help you explain and describe scientific issues and/or statistical data or economic information related to your topic. You will analyze and evaluate these articles in your submission, which should include:
Description Discussion : The integumentary system plays an important role in maintaining homeostasis of body temperature. In your initial post, discuss how one or all of the following tissue types help regulate body temperature: Epithelial tissue (surface area, sweat glands, oil glands) Connective tissue (blood vessels, fat cells) Nervous tissue (temperature sensors) -I know we have not studied them in detail yet, but you can jump over to the nervous system chapter for some inspiration if you’d like! Explain the physiologic mechanisms involving these tissues that help control body temperature when faced with changes like exercise, hot/humid weather, or a fever. Reply to a classmate's post and compare the role of the integumentary system in temperature regulation to how another organ system, like the respiratory system, also helps maintain homeostasis. This discussion aims to connect tissue structure/function to the larger goal of temperature homeostasis. This is just a two-point assignment, so don’t sweat it (sorry, I couldn’t help)! Have fun interacting with and learning from your classmates! OR for this module, you can discuss the Bone Tissue Discussion : The skeletal system plays a vital role in calcium homeostasis. In your initial post, discuss the major anatomical structures and cellular components involved in calcium regulation: Gross skeletal anatomy (compact bone, spongy bone, epiphyseal plates) Microscopic bone anatomy (osteoblasts, osteoclasts, osteocytes) Bone matrix (hydroxyapatite crystals, collagen fibers) Explain how these anatomical features help maintain normal calcium levels via bone remodeling and storage/release of calcium. Discuss the homeostatic feedback mechanisms that regulate osteoblast/osteoclast activities. We have talked about this in the lecture, but you might have to read some more in the textbook readings for this one! Think about including something about How might a condition like osteoporosis disrupt skeletal system homeostasis? Explain the effects on anatomy and calcium regulation. OR discuss the homeostatic roles of the skeletal system in maintaining normal calcium levels. This discussion helps you focus on applying skeletal system anatomy concepts to calcium regulation. You must demonstrate an understanding of bone cell/matrix structure-function relationships critical for homeostasis. Remember, this is just a two-point assignment, so don’t be too hard on yourself (anyone get that? It’s a bone joke!)
Description Provide a summary that includes ALL of the following elements: A short (less than 100 words) biographical summary about the lead author, including their background, any challenges, and major contributions to the field of study.
