Here is a link to our recording from 9/19/24

Here is a copy of the google doc with my notes from this unit.

Here are the slides from the class session.

Our bodies have control systems that help to maintain the condition of Homeostasis. Select the 4 parts that are common to all control systems.

1

Which feedback system is considered inhibitory, meaning it works to stop changes.

Positive feedback

Negative feeback

1

Increasing contractions during childbirth to stimulate or amplify change (in the uterus) is an example of which type of feedback?

Positive feedback

Negative feedback

This is not an example of a feedback mechanism

Modern cell theory has evolved to include three key points:
Which of the following are the parts of the Cell Theory? (there is more than one correct choice - select all 3 correct answers to earn full credit)

All living things are composed of one or more cells.

The cell is the basic unit of life.

New cells arise from pre-existing cells.

Cells are not essential to most life forms

Some life forms can exist without the presence of cells

There is a video that describes the cell membrane embedded in this lesson. You can also watch a similar video here if you would like to see the same information in a slightly different style (both contain the same information)

1

What is the main component of our cell membranes?

Protein channels

Cholesterol

Phospholipids

Carbohydrates

Look at the Test your knowledge questions in 2.02 for help with this question.
Your lab partner says, “I see something that looks like sheets or discs layered on top of one another with little bumps all over it.” Which of the following cell structures are they describing?

Smooth endoplasmic reticulum

Rough endoplasmic reticulum

Ribosomes

Look at the Test you knowledge questions in 2.02 for help with this question.
Your lab partner says “I see a dark round thing in the center of the cell. Wow, it’s so much darker than everything else.” Which of the following cell structures are they describing?

Peroxisome

Nucleus

Vesicle

1

Cellular respiration is the group of processes our cells use to create ATP energy molecules by breaking down glucose.

Tačno

Netačno

1

Passive transport includes processes like Diffusion and Osmosis that do not require the cell to use ATP energy.

Drag the terms to complete the diagram showing two types of cellular division.

Mitosis is the process that makes exact copies of cells to replace old cells and allow our bodies to grow.

Meiosis is the process that makes sperm and egg cells needed for sexual reproduction (we'll learn more about this process in A&P B)

Drugi mogući odgovor:

Anaphase

Prophase

Meiosis I

Cytokinesis

Metaphase

Meiosis II

Telophase

Part 2: What is a Fever?

Watch the video clip on what a fever response by the body is, then answer questions 1, 2 and 3 that follow.

2

What sets your body temperature?

Homeostasis

A part of our brain called the hypothalamus

98.6 F or 37 C

2

How does stress affect your body temperature?

Increases body temperature

Decreases body temperature

Body temperature remains the same

2

How might a fever help your body fight off an infection?

Feed the body with lots of food.

Prevents viruses and bacteria from making more copies of themselves

Get to a fever of 106 degrees because our proteins cannot function at that temperature.

Part 3: Body Control Center

Go to the interactive: Body Control Center Interactive PBS
Click Launch
In this activity, it’s up to you, not the body, to maintain homeostasis in a virtual person. Monitor the displays and use the controls to keep the indicators centered. But don‘t become complacent when you achieve a balance. Our subject will randomly change states—from standing, to running, to resting—and throw off your settings

null

4. After you have launced the interactive, click on each of the 5 body functions to learn more about how these work.

2

Click on the sentence that describes how much sweat a person can release in an hour of intense activity.

This is the only assignment for Unit 2. We'll begin learning about the Skeletal system next. I know this unit is fast and it is meant to be a brief overview of things you learn in detail in Biology.
How are you feeling about Anatomy & Physiology so far? Are you learning new information or is this mostly a review of material you've learned before?
Do you need help going back through any Unit 1 assignments to make corrections?
