Hey there! Hope everyone had a nice, relaxing extended weekend and are ready to get back to work! We are going to be talking about bacteria this week, so I wanted to start with some interesting facts for you to think about:

-Bacteria and Archaea (both prokaryotic domains) vastly outnumber all other life-forms on Earth at about 5

million trillion strong.

-Lined up end to end, they would stretch about 10 billion light years--to the edge of the visible universe.

-Some bacteria can go from birth to reproduction in 10 minutes, potentially giving us more than a billion

offspring in a span of 5 hours.

-Your body houses 10 times more bacteria cells than human cells.

-Some bacteria can travel the equivalent of 135 miles per hour.

Bacteria that float in the atmosphere are very effective at spurring condensation, leading to snow and rain. Some scientists propose spraying bacteria into the clouds to end droughts. What do you think of this idea? What are some issues associated with this concept? Respond to these questions, along with general feelings about the bacteria fun facts from above for your blog post this week.

Have a great rest of the week!

Hey there! Hope everyone is having a great week so far and getting back into the swing of things without too much trouble. This week's blog is going to be related to the article entitled "Dinosaur Resurrection" that you read over the weekend. What do you think about the idea of creating a dinosaur from fossilized remains or altering chick embryos to model dinosaur traits? Do you think you would like to live in a world similar to that of Jurassic Park? Should we grow dinosaurs just because we have the technology to do so? If we open up the floodgates, so to speak, with these technological advancements, where do we draw the line? Please answer these questions and respond to at least one other classmate. Have a great rest of the week!

Hello and welcome to a new school year! I'm hoping this blog site will lead us to some lively debates on current issues 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!). Remember to use an alias name when you post (no anonymous postings, please) and let me know what that name is. Feel free to respond to other students' postings if you so desire. Have a great start to the school year!
