I’m studying and need help with a Anatomy question to help me learn.

Kidneys filter the blood and remove waste and extra fluid from the body and are essential for maintaining good health.

What is one possible reason for kidney failure? Why would someone die if kidney failure occurs?

Humans have two kidneys, but they can survive with one. Given the crucial function of the kidney, would you ever consider donating one of your kidneys to someone else? What factors would go into your decision?

• Hypothetically, what impact would having only one kidney have on a person’s health?

Please answer the questions below in full sentences- I will tip for a great answer, thanks!

1. Your graduate student has created the
following DNA sequence containing a cyclobutane pyrimidine dimer (denoted by
**), as well as several primers to use for primer extension. This will be used
as a test substrate to establish whether Pol4202 can bypass the lesion. Describe
the necessary biochemical components that must be added to carry out this
experiment and why each is required.

2. Interpret the results of the gel below (which was performed using the template and primers from Part A, above, with and without dimers as indicated at the top of each lane). Does Pol4202 possess the hypothesized activity? Recall that Polδ is a replicative polymerase. Describe the expected outcome on this gel for both successful and unsuccessful lesion bypass.

Reflect upon which of the labs completed since the midterm, Labs 8-13, has provided you with a deeper understanding of the concepts covered in the experiment (it may help to revisit the Lesson Objectives for that lab). In 2 paragraphs in a Word document, describe how the lab activities led to this deeper understanding (20 pts).

I’m working on a environmental science test / quiz prep and need a sample draft to help me study.

Answer all of the following essay questions. For maximum points, please use your text and course materials to compose a well-constructed and well-researched response to each question.

1. Present evidence for or against the statement:  “there are too many mouths to feed.  Global population growth has outstripped food production, leading to the high rates of hunger seen in the early years of the 21st century.”  List at least three lines of evidence that support or refute the statement. 

2. Discuss the role of individuals in water conservation. What actions can you take to conserve water? What are the obstacle(s) to these actions, and how might they be overcome? 

3. Identify the major components of soil and discuss the role of each in the support of living organisms. How do differences in the composition of the soil affect the productivity of a particular region? 

4. What are ecosystem services? How would you respond to the critic who says, “Forests are only good for providing timber”? Support your answer with examples of at least four different ecosystem services offered by forests. 

I’m working on a rocket science question and need a sample draft to help me learn.

Assess the benefits and drawbacks of the high-speed rail project. In your opinion, do benefits outweigh drawbacks, or vice versa? Why? Justify your answer.

What are the implications of starting a project based on tenuous projections that may or may not come true 10 years from now?

Could you justify the California high-speed rail project from the perspective of a massive public works initiative? In other words, what other factors enter into the decision of whether to pursue a high-speed rail project? Why are they important?

One approach to study human anatomy is based upon the body’s organ systems.  You may ask, what is an organ system?

An organ system is a group of organs that function together to produce coordinated effects.  There are eleven organ systems in the human body.  For example, the cardiovascular system is one of those eleven organ systems and consists of the blood, heart and blood vessles.  The following is a list of all eleven organ systems you will find in the human body:

1. Integumentary System
2. Skeletal System
3. Muscular System
4. Nervous System
5. Endocrine System
6. Cardiovascular System
7. Lymphatic System
8. Respiratory System
9. Digestive System
10. Urinary System
11. Reproductive System (Male and Female)

The eleven organ systems listed above allow the human body to carry out the essential functions such as growth, movement, responsiveness to our environment, reproduction and excretion of waste.  To understand the 11 organ systems of the human body and the essential functions that each of them enable us to perform, please watch this short 10 minute video that gives on overview of the eleven organ systems.

As you wat

ch this video, please note the primary functions and the organ components of each organ system.

Organ System Integration

Assignment Objectives

Demonstrate that you can accurately understand what organ systems are, identify which organs belong to each organ system, and the function of each organ system and how organ systems interact to carry out a specific bodily function.

Instructions

PART 1: Discussing Body System (2.5 points)

Now that you have learned about the eleven body systems in the human body, as well as the organs and functions that each contain, I would like you to pick your favorite body systems and begin to think about this body system in more detail.  In your response, include the following details.  Please number your response from 1 to 4.

1. Include all the organs that make up this body system.
2. Explain how each of the organ’s function help achieve the overall function of the organ system you chose.
3. Explain why this is your favorite body system.
4. Give one disease that afflicts this body system and explains what specific organ or organ is affected by this disease.

Initial post due by Wednesday at 11:59pm

PART 2: Peer Responses (5 points)

Once you have written your response, you are to respond to two of your peers’ paragraphs in at least 150 words each. Respond to a posts that have yet to be responded to by a classmate. If everyone’s post has been responded to, then respond to the ones with the least amount of responses. For example, if every student has at least one response, then evaluate the students who only have one or two responses instead of those who have 5 or 6 already.

Be sure to address your peer before responding. In your reply, respond to how your favorite system is needed for your peer’s favorite system to function properly. And the end of your response, describe a disease that afflicts your favorite organ system and the favorite organ system of your peer.

R1: Cardiovascular system

1. In the cardiovascular system there is the heart, arteries, veins and capillaries.

2. The heart is what is responsible for keeping blood moving throughout the system. Blood is pumped in and out to deliver oxygen throughout the body. This pumping and delivering of blood cannot be done with the arteries, which are responsible for carrying the blood away from the heart. The arteries bring the blood to the capillaries which diffuses gases and nutrient wastes. From the capillaries, blood is brought to the the veins and then brought back to the heart.

3. This is my favorite system because I feel it has the most relevant information. Heart problems are very common, especially in my family, so I like to know the physiological aspect of what is happening. Also this system is one of the most important in terms of someones health.

4. A disease common in the cardiac system is Arrhythmia. Arrhythmia is when the heart is pumping blood at irregular rates, either too fast or too slow. The heart is affected by this disease when the electrical impulses are not working properly.

R2: The Organ System that I chose is the Nervous System.

1. Include all the organs that make up this body system. The organs that make up this body system are the brain, spinal cord, nerves to body parts.

2. Explain how each of the organ’s function help achieve the overall function of the organ system you chose. The organs help function the body by regulating body activity.

3. Explain why this is your favorite body system. This system is one of my favorites because it is the central communication for what helps get our body going by sending signals. Without this system, the human body would be completely useless and the other organ systems would not be able to function without it.

4. Give one disease that afflicts this body system and explains what specific organ or organ is affected by this disease. Alzheimer’s disease is one of the diseases that affects the nervous system and more specifically the brain. This is due to the nerve cells in the brain die. When this happens, the brain or nervous system is no longer capable to communicate with the rest of the body. Unfortunately there is no cure for this and the disease gets worse over time.

Overview

Colleges and universities have begun offering online classes in order to attract a global audience. The concept of online classes was once considered challenging and complex. Today, schools have become more proficient in developing systems that serve thousands of students living anywhere in the world. These systems, sometimes called learning management systems (LMS), display course content, manage different user accounts, store grades, and more! In this assignment, you will research an LMS of your choice and how it provides its users with secured interaction, content, technical support, and more. You may also use your own experience as a student using Brightspace, Southern New Hampshire University’s LMS. With your knowledge of the system and your experience as a student, you will assume the role of a systems analyst who is designing a similar system for YOUser University, a new college offering online courses.

Prompt

Assume the role of a systems analyst designing an LMS for YOUser University. You have been asked to determine different functional and nonfunctional requirements for the new LMS. You have also been asked to determine limitations and assumptions for your system design. You will be asked to provide a rationale for your work, and to support your reasoning with quality sources.

• Research learning management systems used at other colleges. Commonly used LMSs include Brightspace, Canvas, Blackboard, and Moodle. Additionally, you may consider your own experiences as a student. Here are a few questions you might consider to guide your research:
  • What different functionalities do these systems have? What different functions do the systems perform?
  • What behavioral properties do these systems have?
    • Who are the different users and what types of access do they have?
    • What platforms do these systems operate on?
    • What security measures do these systems use?
    • How do these systems back up and recover data?
• Based on your research, complete the Module Two Assignment Template included below. You will describe the requirements, assumptions, and limitations for the LMS you are designing for YOUser University. Be sure to do each of the following:
  • Identify six different functional requirements for your LMS. For each requirement, you must include a rationale that explains why you chose that specific requirement.
  • Identify six different nonfunctional requirements for your LMS. For each requirement, you must include a rationale that explains why you chose that specific requirement.
  • Identify two assumptions and two limitations for this LMS design project. For each assumption and limitation, you must include a rationale that explains your choice.
  • Finally, be sure to include citations in APA format for the sources you used to help you determine different requirements, or explain your rationale.

TIP: The Module Two resources contain helpful links and examples of functional and nonfunctional requirements, assumptions, and limitations for different types of systems. These examples, in addition to your research, may be helpful to review as you complete this assignment.
