Describe the structure of your ecosystem including important abiotic features and dominant plant and             animal species.

Ecosystem Paper

This is a TWO part paper which must consist outside reference – APA format not needed as it will be plugged into another sheet.
PART 1 – 
Select an ecosystem in your area (forest, lake, desert, grassland).
Write a 525- to 700-word paper explaining the following:
1)   Describe the structure of your ecosystem including important abiotic features and dominant plant and             animal species.
2)   Explain some functions/processes of your ecosystem including one nutrient cycle and one food chain.
3)  Give two examples of species interactions (predation, competition, mutualism, etc.) that occur in your ecosystem.
4)  Identify an invasive species in your ecosystem. Explain its effects on the ecosystem and efforts to control or eradicate it.
Include two outside references
PAST 2
Using the textbooks or resources, answer each of the following questions in 150- to 300-words.  Be sure to provide references for the sources you use
1)    Your neighbor faithfully applies fertilizer to his lawn to ensure beautiful, healthy green grass.  Explain how your neighbor’s fertilizing habit affects at least one nutrient cycle.
2)    Your friend commutes to work every day by driving a standard gasoline-powered car.  Explain how your friend’s commute affects one or more nutrient cycles.
3)    Urban areas typically have lots of pavement and compacted soils.  Explain how these impermeable surfaces affect at least one aspect of the hydrologic cycle
4)     Why is understanding the cycling of matter and energy in ecosystems important to environmental science? Provide an example.  What are some human effects on the natural cycling process of ecosystems in your community?
5)     Because ecosystems change and may recover naturally from disturbance over time, what factors affect decisions about whether human intervention is needed to help ecosystem recovery? Provide examples.

Introduction
Heart disease is the number one killer in the United States. One procedure to treat blockage in the arteries of the heart is bypass surgery. Someone you know may have already had this procedure; however, few people really realize what occurs during the surgery. The following lab will guide you through the steps of a virtual bypass surgery.
Objectives
1.     Identify the major structures and functions of the cardiovascular, respiratory, urinary, digestive, and immune systems.
2.     Evaluate various risk factors for diseases within body systems.
3.     Relate homeostatic imbalances to disease states.
4.     Discuss various treatments, cures, and procedures for common diseases.
Materials
Computer with internet access
Directions
1.     Go to the following website: http://www.abc.net.au/science/lcs/swf/heart.swf (or http://www.abc.net.au/science/lcs/heart.htm)
2.     Click on ENTER
3.     Click on ANATOMY to review the anatomy of the heart.
4.     When you are ready to conduct the surgery:
a.     Select INTERN from the three choices provided (Intern, Surgeon, Specialist). This will allow you more time.
b.     Make sure you read all information on the screen.
5.     Type all answers directly on the data sheet. All answers must be written in complete sentences.
6.     Select Save As, and use your last name and student ID as a file name.
7.     Upload the data sheet as a .doc, .docx, or .rtf file when finished.
Questions 1 – 10 are short answer questions and should be answered in two to three words or one to two complete sentences. Total: 60 points
1.     Which chamber of the heart receives oxygen-depleted blood from the superior and inferior vena cava? (6 points)
2.     Which chamber of the heart pumps oxygenated blood to the rest of the body? (6 points)
3.     How much blood can the heart move the through the body in an average lifetime? (6 points)
4.     How is the patient’s anxiety level reduced before surgery? (6 points)
5.     What are the responsibilities of the perfusionist? (6 points)
6.     What are the responsibilities of the anaesthetist? (6 points)
7.     What vein is harvested from the leg to be grafted to the heart? (6 points)
8.     What is the name of the membranous sac that encloses the heart? (6 points)
9.     What is injected into the heart to stop it from beating? (6 points)
10.  In your own words, what is the purpose of the drug protamine? (6 points)
Question 11 is an extended response question. Your response should go into significant detail and should be at least 200 words. Total: 40 points

Significance of Major Discoveries in Modern Biology

PART 1
Gene Therapy and Cloning
Cloning is a major topic of debate and is described in the textbook. Briefly describe the process of cloning in the lab incorporating facts.
How is cloning involved in gene therapy?
Give a specific and detailed example of how gene therapy may be used to solve problems associated with genetic disorders. Discuss the benefits and possible hazards of gene therapy to human health.
What might be the benefits of cloning? What are potential dangers or threats associated with the widespread use of cloning? Discuss the ethics of cloning in its various proposed forms and uses. Discuss how cloning is related to GMOs. (200 words max)

The purpose of this assignment is to explore approaches to instruction that support adolescents’ physical, cognitive, or socioemotional growth and to understand the unique challenges adolescents face with regards to classroom learning.
Respond to each of the following scenarios with a 500-750 word rationale. Your response to each scenario should include the following:
Assessment of developmental characteristics of adolescent behaviors.
Explanation of specific challenges the student is facing, based on developmental characteristics and behaviors.
Approaches to instruction that promotes the physical, cognitive, or socioemotional development of each student.
Opportunities to facilitate learning with the use of technology.
Scenario #1
Marco is a senior in one of your classes. He has appeared to be depressed, showing signs of sadness, self-criticism, and hopelessness. As a result, his grades have dropped. You are considering whether to use the Response to Intervention approach to provide more guided, supportive instruction to Marco.
Explain how and why you might use Response to Intervention (RTI) to support Marco’s learning in your classroom. Offer specific intervention strategies and steps you will take, including the use of technology in your response.
Scenario #2
Megan, a sophomore in one of your classes, has been struggling with substance abuse and chemical dependency for the last year. She is now on an Individualized Education Program (IEP). Tasks that involve memory and retention of information pose a challenge for her.
Explain how you might help Megan in the classroom by supporting her capacity to remember/retain information, enhance her study skills, and organize and process her thoughts.
What strategies might you use to support her learning? Explain why you selected these strategies. Include the use of a technological tool as a means of supporting her learning in your response.
Support your findings with a minimum of three scholarly resources.
