Briefly describe the environment

/in /by

Identify an organism that lives within 50 miles of your home.

Write a 1,050- to 1,400-word paper about how the organism has adapted to survive in their specific environment. Include the following points in your paper:

  • *Briefly describe the environment (temperature, landscape, food sources, etc.) and describe the organism’s role in the environment. Determine which organism your chosen organism would be most closely related to using a phylogenetic tree.
  • *Identify the structures and functions of the main organs found in your selected organism.
  • *Explain how the organism has evolved physiologically to become suited to its environment.
  • *Explain how things would change if the organism were to be transplanted to a significantly different environment: 
  • *Would their organ system still be as efficient? Why or why not? 
  • *Would the organism survive in this new environment? Why or why not?

Include the diagram and other appropriate pictures in your paper and make sure to provide a full reference for the images in your reference section. 

Format your paper consistent with APA guidelines including references and in-text citations. Your paper should include a well written introduction and conclusion. Use only academic research sources.

Photosynthesis

/in /by

The Introduction:

Photosynthesis is arguably one of the most important processes on Earth – essentially all life depends on it. Humans and other animals depend on plants to capture the energy of the sun and use that energy to manufacture carbohydrates – subsequently releasing the oxygen that we breathe. But plants are vital to our lives in other ways as well. Think about the pencil you write with (or used to), the toothpick you used last night, the cotton T-shirt you wore today or the maple syrup you had on your pancakes this morning. These all came from plants! Ethnobotany is the study of the relationship between plants and people – plants used for practical, ceremonial, spiritual, medicinal, decorative, edible, etc. purposes.

You are to find a plant product that we use every day.

Make sure to include the product name in the title of your forum post so that others can quickly see what you have chosen.

Do some research and address the following:

From what plant does your product come? Include the common and scientific name (properly formatted).

What is the product? What does it do? How do we extract it from the plant. Describe in detail.

What is the primary use: medicinal, ceremonial, etc.?

Are there commercial fields for the plant? Where?

Are there any substitutes for your product? If there is no information, feel free to take an educated guess and support it.

What is the most fascinating thing you learned about your product?

What did Frank mean by his statement above?

/in /by


Topic 3 [article]:  Earth will survive; we may not.  Astrophysicist Adam Frank says that “pretending we can just extend the Holocene in perpetuity” is just a foolish excuse to put off making inevitable choices brought about by climate change.

  • (a)  What did Frank mean by his statement above?
  • (b)  Some biologists, particularly conservation biologists reacted negatively to this essay. What is your reaction to this essay?
  • (c)  Share what you feel this teaches you about biology (the study of living organisms).

Immunity and the Lymphatic System

/in /by

Immunity and the Lymphatic System

This week you will delve into the complex world of our immune and lymphatic systems. Here you will discover how this system protects and defends the body from various external and internal stressors. You will learn how the three stages of General Adaptation Syndrome or GAS helps us deal with stress. You will also learn about the three lines of defense: skin and mucous membranes, innate defense as well as the lymphatic system and specific immunity. You will also discuss what happens when this system fails to work properly.

Reading- Chapter 9: “Immunity and the Lymphatic System”

Discussion- Oh…My Crazy Stress Hormones!

Annie is a new district attorney (DA) for her county and she has her first day in court. She walks into the courtroom and sits at the plaintiff’s table. She feels pretty relaxed and is excited about her first case as a DA; but she is also nervous. The judge enters the courtroom, introduces the case and asks Annie to make her opening statement. As Annie begins to stand, she suddenly feels terror, her hands are trembling, her heart is racing, her mouth is dry and she thinks that she may faint.

  1. What is Annie experiencing?
  2. What are the three stages of General Adaptation Syndrome (GAS)?
  3. What stage is she currently experiencing? What hormone is released during this phase and how does it affect the body?
  4. What are the main organs involved in this response?
  5. What techniques do you recommend to help Annie calm down?
  6. Think about your own experiences. Describe an incident where your system activated the “fight or flight response.’

a. What caused this reaction?

b. How did you feel?

c. What was the outcome?

d. Be sure to explain in your example how many of the GAS stages you experienced.

  1. What is post-traumatic stress disorder (PTSD)? What stage of GAS is affected in PTSD?
  2. What treatments are available for PTSD?
