Situs inversus totalis (SIT)! No, this is not a spell from a book of magic, but rather a rare medical condition estimated to occur in 1 out of 10,000 births. The term is Latin and translates to total opposite location, referring to a reversal in the placement of all abdominal and thoracic organswhat should be on the left is on the right and vice versa.

Background:

several types of cells using the light microscope, including animal cells (cheek and liver cells) and plant cells (Elodea and onion epidermis). You also learned about cell theory, cell classification, and the functions of major organelles, as presented in the lab manual and reinforced in the lecture PowerPoint.

Discussion PromptsInitial Post (Required 300 words)

Respond to ALL parts below:

1. Cell Theory in Practice
2. Based on your observations in Exercise 6, explain how your microscope observations support cell theory. Provide one specific example from either the animal or plant cell slides
3. Comparing Cell Types
4. Choose one animal cell and one plant cell examined in the lab.

• Identify two structural differences you observed
• Explain how each difference relates to the function of that cell (for example, presence or absence of a cell wall, chloroplasts, or vacuole)

1. StructureFunction Connection
2. Select one organelle discussed in the PowerPoint (e.g., nucleus, mitochondria, chloroplast, plasma membrane).

• Describe its structure
• Explain why its structure is well suited to its function

Instructions

In this discussion, we discuss intracellular organelles. Pick the organelle that interests you the most. Do not attempt to complete this discussion until you have read the appropriate sections in Chapter 3. You will be able to see your classmates’ posts before you post yours, so check in before you choose your organelle. Once an organelle has been selected three times, it is off limits and you should pick a different one. For your original post you should:

• Define the organelles structure
• Detail the organelles function(s)
• Describe interactions with other organelles
• Include both a drawn image and a microscopic image of the organelle
• Discuss at least three problems or diseases that can occur when organelle malfunctions

Guidelines

• Write a minimum of 400 words.
• Use appropriate APA citations when you are using a source.
• Use your own intelligence to create your post and responses.
• You cannot collaborate with other students.
• You cannot use Generative or Artificial Intelligence, such as ChatGPT, Gemini, Copilot, and Jasper.
• You cannot use or post your answers to peer-to-peer collaboration “study” sites like Quizlet, Studyblue, and Coursehero, etc.

use the organelle: ribosomes

This assignment is in preparation for for research paper.Assignment is due end of Week 5.

Provide a total of five references (minimum) you will use in your research paper. For each of the five reference you will provide the APA7 student paper formatting that will appear in your reference section as well as the intext citation format you will use within the body of the paper. Avoid use of reference formatting generators or AI.

Please begin researching a topic of interest to you. Gather preliminary resources and journal articles. You may write a thesis or thesis question related to biology for your research paper. View the video on this instructor teaching his class how to form a scientific question.

Please submit research paper topic and thesis statement for approval. Remember your thesis statement should be in the form of a question. Please check for my feedback in Grades for my comments on your choice.

Welcome to Week 2! This week, you will be introduced to tissue types, levels of organization, and the integumentary system.

Scientists make predictions using the best possible and most available knowledge that they have at the time. Sometimes the predictions end up being correct, and sometimes they are not. For this discussion, you will practice making predictions based on what you see when you quickly skim through a portion of the textbook.

Skim Ch. 4, The Tissue Level of Organization, and Ch. 5, The Integumentary System, of Anatomy and Physiology. You will not need to read these chapters in full to answer this discussion question. (You will read the chapters later this week as you complete your activities and assignments.)

Select one chapter section (e.g., 5.2, Accessory Structures of the Skin).

Complete the following in your discussion:

1. List the section you selected.
2. Predict how the section you selected might add to your understanding of the learning goal for this week: Summarize the levels of scientific organization for chemicals, cells, and tissues.
3. Predict how information from the section you selected might help you in your future career. Also, discuss how not knowing the information might hinder your future career.
4. Pick one image, figure, or graph from the section that stands out to you and briefly describe the image. List the page number, and figure title of the image (e.g., Figure 5.11, Hair Follicles, p.192). Discuss what made the image interesting to you and why you selected it.

you will response to 2 when they post I will let you know
