AP Biology--Blog 3

Hey there! Hope everyone had a great weekend. This week's blog post is about carbohydrates (sugars) and their possible role in life on Earth. Sugars are the building blocks of carbohydrates, the most abundant type of organic molecules in living things. Glycolaldehyde, an eight-atom sugar, has even been found in an interstellar gas cloud near the center of the Milky Way. Glycolaldehyde can react with a three-carbon sugar to form ribose, the basis for both RNA and DNA, so the glycolaldehyde found in deep space may be a chemical precursor to life on Earth. That cloud also contains ethylene glycol, a sweet relative of glycolaldehyde and the main ingredient in antifreeze. Either complex sugars can be synthesized between the stars or there is a truck stop at the end of the universe. In your blog post this week, please respond to this idea from Discover magazine as well as to one other blogger's post. If you are this first to respond, you will need to get on again later this week. Have a great day!

AP Biology--Blog 2

Hello! I hope this finds everyone relaxed and refreshed from a nice weekend. Last week we talked quite a bit about characteristics of viruses and what makes a good/virulent/dangerous virus. In your opinion, what is the most frightening/concerning thing about viruses? Please respond to this question, including an explanation for your viewpoint, AND respond to at least one other students' response. Have a great week!

AP Biology--Blog 1

Hello and welcome to a new school year! I am so excited to have you in AP Biology this year...I can't wait to read what you have to share for your blog postings!  Hopefully the responses on this site will lead to some lively debates on current issues in Biology and a deeper understanding of some of the concepts we will cover this year. Please help me begin this segment of the class by posting a response to this message, telling me: 1. One cool thing you did this summer, 2. Where your interests in Biology lie, and 3. Why you have signed up for this class (no pressure here, just be honest!). Please post using an alias name and then let me know what you have chosen to use throughout the year.  Feel free to respond to other students' postings if you so desire. 

Have a great start to the school year!
