Last week we watched a Ted Ed about bacteria. It showed us the amount of human cells in a body and the amount of bacteria in a body. Human cells are outnumbered. Ten to one. It also showed the amount of genes in a body and the amount of bacteria genes. We have around twenty thousand genes. All the bacteria in a body have twenty million. The Ted Ed also talked about how bacteria communicate. They use chemical molecules in a process called quorum sensing. Another thing that they mentioned was that when bacteria want to make us sick, they send messages to each other and attack all at once. But, certain people are working on a type of medicine that deafens or prevents the bacteria from communicating.
We learned a lot about bacteria. We learned that there are some that are good and others that are bad. We learned that they have a way of communicating. We also learned that when we take too many antibiotics, it kills to many of the good bacteria. Also, the bad bacteria adapts and evolves into super bugs. That’s why people are working on a new type of medicine. Watching the video, I was surprised by a few things. One of the things I was surprised by was how many bacteria to human cells there are. It’s strange, thinking about how we are more bacteria than human. Another thing was that they can actually communicate. How long will it take to develop the new medicine? How small is the smallest bacteria? What type is it? Good or bad?
Hi savannah! The thing about bacteria communicating is cool! I wonder if it’s always been able to do that. I also wonder what size Bacteria normally is. Your blog had a lot of interesting facts like the thing about bacteria and cells being 10 to one!
