I’m working on a biology question and need support to help me learn.
Choose one of the following:
#1 Construct the process of mitosis starting from prophase to metaphase. Your explanation must include a written and visual (picture) representation that should be uploaded for credit. Clearly identify each stage and give a description of the process. You can use household items to demonstrate your understanding.
#2 Construct the process of cellular respiration from glycolysis to the electron transport chain. Your explanation must include a written and visual (picture) representation that should be uploaded for credit. Clearly identify all three steps and give a description of each process.

Microorganism Profile
Introduction
This project requires the ability to understand and apply scientific knowledge that you acquire both inside and outside the microbiology classroom. You will construct a comprehensive profile of a microorganism that you are assigned by the instructor. This microorganism is a pathogen that you may encounter in your nursing career. All written answers are expected to meet accepted standards for grammar, syntax, and punctuation and follow APA format. Proper microbiology terminology is also expected. The completed APA paper is to be submitted electronically via the Assignment Drop Box in Canvas. Total APA paper should be between 5 to 7 pages including a title and reference page.
The Big Picture
As you progress through this course, you will acquire information in a sequential, topic-specific manner. Each topic will include information that is relevant to this assignment. For example, the knowledge you gain from the lesson on bacterial cell morphology will be applied to the first paragraph topic, Cell Morphology and Growth Requirements. Your answers are expected to include information from sources that go beyond the textbook or classroom. Examples include peer-reviewed journal articles, interviews with clinicians who deal with microbes on a daily basis, personal experiences, and other reputable sources. You are expected to clearly understand the meaning of each topic before you construct your answer. For example, you are expected to know the meaning of “epidemiology” and to understand the topics that are connected to it. Don’t forget to read and understand the rubric before you start. Refer to it often – it will help guide you through the process. Name of Microorganism: ________________________________________________________
1. Description of the Microorganism (week 1)
Write a paragraph describing your organism. Please be sure to include the type of organism (bacterial, viral, fungal, protozoa, helminth, etc), morphology (shape, arrangement , colony morphology if applicable), description of structure (gram result, type of nucleic acid or virion structure, spore type, etc if applicable) and also the type of microscope and/or stain you would use to view the organism. Please use proper scientific terminology and good grammar and sentence structure throughout this project.
2. Virulence Factors
Include a paragraph on the virulence factors the pathogen has and how they affect the host. Please enhance this with detailed explanations of the virulence factors and how they affect the host as you gain a better understanding of them throughout the semester.
3. Immunity
Which innate and/or adaptive defenses protect us from infection by this bacterium?
Does this pathogen induce a specific type of immune response (example: delayed-type hypersensitivity)? If so, which one(s)?
4. Pathology (Infectious Disease Information)
What condition(s) or infectious disease(s) does it cause?
Which tissues or organs are affected, and how are they affected (for example, chronic TB is characterized by lung tubercles)?
Describe the complications that can result if the infection is left untreated.
Are these acute, chronic, or latent infections?
What organ system(s) does it infect?
Is it an opportunistic pathogen? If so, where is it normally found in the body?
5. Epidemiology
Draw and label a diagram on how this organism is transmitted. Make sure you include the reservoirs of infection, any vectors if involved in transmission, the type of transmission, and portals of entry and exit.
6. Prevention
Is there a childhood vaccine against this microbe? Name of vaccine
If so, when is it administered (the recommended schedule, including boosters if recommended)?
If the vaccine is not recommended during childhood, which at-risk group should get the vaccine, and when?
Describe the type of vaccine and how it works :
If there is no vaccine available, list at least three measures the can be implemented to prevent people from acquiring this infection.
7. Treatment
Chemotherapeutic agents: antibiotic or antiviral etc. used to treat.
Mechanism of action for these chemotherapeutic agents.
Why is this agent efficacious against this particular organism ?
Additional therapeutic agents or practices.
If there is no treatment specific for your organism what measures are take?
8. Clinical relevance
Are there any MDR (multi-drug resistant) strains of this microorganism? If so, name the strain(s)
Is this strain a known healthcare-associated pathogen?
Which persons/procedures within a clinical or healthcare-assisted setting are particularly at risk
Which antibiotics are used against the multi-drug resistant strains? Be specific
9. References
Include at least 4 APA style references (scientifically appropriate credible resources) that show where you found the information in this microorganism profile.

APA 7th edition Title page:
This is a separate page by itself, with the following information centered in the middle of the page: course title, paper title, student’s name, instructor’s name, and date.
Description of Pathology:
Start the paper on a new page.
In this section, you will describe the pathology (statistics about it, background information, etc.). Give as much information as you can about it but be sure it is relevant information and not just filler. It should be a comprehensive introductory section of the condition in one to two paragraphs.
Normal anatomy of the major body system affected: In this section, you will describe what is considered normal anatomy for your particular pathophysiology. For example, if you are discussing a disease related to the brain, explain what is normal for the brain from an anatomical standpoint. You should show comprehensive knowledge of the fundamental concepts and communicate information using scientific vocabulary. There should be little to no discussion of the condition itself in this section.
Normal physiology of the major body system affected: In this section, you will be discussing physiology. Keep in mind that when describing physiology, it isn’t enough to merely provide a list of functions of the body system (Ex: Neurons send signals throughout the body), instead, you need to be able to describe how it does it. The how is the physiology. There should be little to no discussion of the condition itself in this section
Mechanism of Pathophysiology: This section is likely going to be the most in-depth and longest section. In this section, you will explain your particular pathophysiology from a scientific standpoint. In the previous two sections, you explained what is considered normal, in this section, you should describe what the pathophysiology is doing that is causing these issues, how the normal anatomy & physiology is affected/different in a person with your condition. You should show a thorough understanding of the anatomical and physiological changes contributing to the disease. Some good keywords to search for when doing your research might be “Pathology of __________”, Pathophysiology of __________.”
Prevention: In this section, you will explain how your pathophysiology could be prevented. This should outline possible prevention protocols, or clearly indicate if none is available based on the current scientific literature.
Treatment: In this section, you will explain how your pathophysiology is commonly treated. Provide possible treatment protocols for the condition based on current scientific literature. Be sure to bring in nursing relevant information and how you might be involved in the treatment of the condition.
Conclusion: Finally you should summarize your findings. All good research papers should include a conclusion where you wrap up and summarize all of the important points made in your paper.
References:
As with the Title page, this should be a separate page by itself.
All references should be included in correct and complete APA format.
All references must be cited appropriately in the paper using APA-style in-text citations.
A minimum of three reputable sources are required for this assignment.

For the second virtual lab we will focus on practical application of the principles you have learned to a commonly used medicine. Antagonists or inhibitors of molecular drug targets can reduce the activity of the target and any downstream signaling or metabolic pathways. In doing this , they may produce beneficial or therapeutic effects (e.g. reducing blood pressure, reducing psychotic symptoms, reducing acid secretion into the stomach). However, inhibiting the function of a target can also cause toxic effects (e.g., hypotension, extrapyramidal symptoms, etc.). Understanding how much and how long a target and its pathway needs to be inhibited is a critical part of the information needed to use a medicine safely and effectively.
When studying molecular target, we can often use genetic knockout models (mice, yeast, cell lines) to understand the biological consequences of reducing the cellular effects of the target gene/protein/molecule. Gene knockouts permanently remove the target and its cellular effects. Antagonist drugs may be administered using different regimens to achieve block the receptors partially (e.g. 50% target occupancy or pathway inhibition), mostly (e.g.>75% pathway inhibition) or completely (>99% pathway inhibition).
