Biology homework help

Topic: Respiratory Syncytial Virus

This microbe has been in the news in the past year.You must provide a written review a major news article focusing on the  microbe as the primary discussion!Find a media-based, mass-distributed news source where even Grandma gets her news, that reported the microbe within the past year, as the main reference.Use government-based or other scholarly references only as secondary information, to explain details missing above such as, how the organism affects us, or follow -up information not known at the time of the news release but has been provided since that time.

You must write a review of the news article contents, discuss what type of microorganism it is, and if the organism is in nature or is used in industry or causes disease. If it causes disease you must discuss transmission, increasing incidence, factors contributing to the spread of the organism, lab culturing, etc.

  2. Use the M.U.S.E. link to complete the lab for this Unit.
  3. Track your results in the lab worksheet that is provided.
  4. Complete a lab report using the scientific method.
  5. Submit your completed lab worksheet to the assignment box.

Using the Scientific Method Lab

Establish a better understanding of photosynthesis and cellular respiration, and apply the scientific method to solve (or understand) a problem. Photosynthesis and respiration are reactions that complement each other in the environment. They are essentially the same reactions, but they occur in reverse. During photosynthesis, carbon dioxide and water yield glucose and oxygen. Through the respiration process, glucose and oxygen yield carbon dioxide and water. They work well together because living organisms supply plants with carbon dioxide, which undergoes photosynthesis and produces glucose, and these plants and bacteria give out oxygen, which all living organisms need for respiration.

Using the M.U.S.E. link, review the background information and animation to complete your report. Use the lab 1 worksheet for assignment instructions and data collection.

Please submit your completed assignment in your assignment box.

Compare the definitions of Acute Infections and Chronic Infections

/in /by

Question: Compare the definitions of Acute Infections and Chronic Infections below. Based on what you know about HIV/AIDS at this point, which description most closely matches AIDS? Explain your answer, using evidence from the book to support your position.

What is an acute infection?

1. Produces symptoms and makes a person infectious soon after infection.

2. The infected person may:                                                                                                                                                                                          transmit the disease

die from the infection

recover and develop immunity

3. the acute microorganism

STRIKES QUICKLY

infects entire group (small group)

dies out

What is a chronic infection?

Person may never show symptoms

Person continues to carry infectious agent at a low level

Does NOT mount an effective immune response

Subtopic 4: Controlling infectious disease

Question: Explain what herd immunity is and how it works. Use an example from either the book or the internet to explain your position.

Herd immunity = when all, or nearly all susceptibles are immunized, no new infection can occur. Agent can be eradicated from the population.

Subtopic 5: Modern concepts of Infectious Disease and Koch’s Postulates

From the Oxford Dictionary:

Definition: postulate

verb |ˈpäsCHəˌlāt| [ with obj. ]

1 suggest or assume the existence, fact, or truth of (something) as a basis for reasoning, discussion, or belief: his theory postulated a rotatory movement for hurricanes | [ with clause ] : he postulated that the environmentalists might have a case.

a thing suggested or assumed as true as the basis for reasoning, discussion, or belief: perhaps the postulate of Babylonian influence on Greek astronomy is incorrect.

Robert Koch was a physician/scientist in the 1800s who studied the transmission of infectious disease. He proposed 4 postulates, also known as Koch’s Postulates (p. 12-13) help control the spread of infectious disease.  He proposed that a microorganism can be considered to be a disease if it fulfills certain criteria or conditions. These are listed on p. 12 in the textbook. The book also goes on to describe how these postulates helped to prevent the spread of the plague pandemic in the late 1800s.

Question: Using what you learned from the movie “And the Band Played On”, described the ways that Koch’s postulates helped scientists to identify what was going on with this new acquired immune deficiency syndrome (AIDS), and to help it from exploding completely out of control.

Module 2 Reflection

In each module, we’ll have a final discussion to “reflect” on what we learned this week. Here you can post commentary on something that we discussed, how a concept would apply to a particular situation, etc. For Week 2, why don’t you each just tell me a new insight that you learned about infectious disease. You can make multiple posts if you’d like, or pose questions for additional discussions. be creative. Everyone should make at least one meaningful comment, and that should be at least 100 words.
