9/30 Biology Recording - Intro to the Biological Molecules

Part 1

Part 2

9/30 Biology class and homework due 10/7

Hi folks,

Today we discussed a bit of homeostasis and positive and negative feedback loops.  We also scratched the surface of the 4 major biological molecules. We will spend quite a bit more time on that next class.

There will be no quiz next week but I HIGHLY recommend taking that time to really nail down those prefixes and suffixes, the fuctional groups and memorize the other material we've covered up to now.  Don't worry too much about about today's molecule table yet.  We will be spending a lot more time with this in the next couple of weeks as we really add quite a bit of material to today's skeleton of a table.

For homework this week:

Read this website regarding homeostasis and answer the following questions that can be found in the reading.

1.  What are three things cells need to survive?

2.  What is homeostasis?

3.  What is negative feedback? 

4.  What is positive feedback?  

5.  Which is more common in biological systems, positive or negative feedback?

6. Give 3 examples of negative feedback.

7.  Give an example of positive feedback.

8. Give three examples of homeostasis in mammals.

9.  What is the job of the endocrine system?

10.  What are two basic ways disease and cellular malfunction can be caused?

11.  How does nutrition play a role in homeostasis?

12.  How does physical activity play a role in homeostasis?

13.  How does mental health play a role in homeostasis?

14.  Last but not least, how about environmental exposure?

Clarification for Biology Homework

Hi folks,

Just to clarify, the questions I'd like you to answer this week are at the end of the chapter on page 26.

9/23 Biology Recording - 7 characteristics of life and the functional groups

Part 1

Part 2

9/23 Bio update and homework due 9/30

Hi folks,

Happy first day of Autumn everyone.  Otherwise known as the fall equinox.  Today's the day we will have equal amounts of daytime and nighttime and from here on out we get less and less light until the winter solstice.  

Today we discussed the 7 characteristics of life.  We also touched on our next unit in which we will be getting into the 4 biological molecules.

For homework this week:

Read pages 3 - 19

Answer questions  3 - 21.  

Be sure to study the 7 characteristics of life and the functional groups.   Both are very likely to be on an upcoming quiz.

9/16 Biology Lecture - Biases and Water

Part 1

Part 2

9/16 Bio update and homework due 9/23

Hi folks,

Today we learned a bit more about science in general by taking some time to discuss bias.  Bias is certainly something you want to keep in mind when looking at your own studies or when looking at other people's studies.  

We also spent some time seeing how special and important water is to life on this planet.  

For homework this week:

Read the text pages 31 - 44

Do Section 1 Review on pg. 34 #'s 1-6 and 8.

Do Section 3 Review on pg. 44 #'s 1 - 6

Also, be sure to study your notes from today's lecture.

Next weeks quiz will have questions based on this homework, last week's and today's lecture and the prefixes and suffixes.

Best,

Prefix and Suffix Quizlet!

Hi everyone,

I've decided to use a bit of technology to help us out here.  I've created a Quizlet with the prefixes and suffixes I'm expecting you to know.  Check it out.  There are a couple of little games here that are a lot of fun and really do help to learn the terms.

Here's the link to the Quizlet.  https://quizlet.com/_70zzpe

Have fun!

9/9 Biology Recording - Intro to class and syllabus overview

Part 1

Part 2

9/9 Biology update and homework due 9/16

Hi Everyone!
Every week, I'll be sending out an email with a quick summary of what we did in class. I also send a recording of each class so that folks who miss class or who would like to review the material can take a look. That is usually posted to YouTube within 24 hours. The recordings are "unlisted" so that they can only be viewed by folks who have the link.
This week we covered some administrative stuff such as homework, quizzes, grade reports and we went over a basic syllabus for the year.
We also talked a bit about the difference between a hypothesis and a theory and what it takes for something to become a scientific theory.
For your convenience, I have a blog that contains all class emails and videos.  The location is 2019carybio.blogspot.com.
For homework this week please do the enclosed .pdf.  Also, begin memorizing all the prefixes and suffixes on the .pdf.   There are a lot but many of which you probably already have an idea as to what they mean.  This would be an excellent time to get those flash cards going.  There won't be a quiz next week but they will be scattered on upcoming quizzes so please take the time to get to know them.
Best,

Jim Mueller
