Class Reflection
The following unit we did in class has so far been the most fun. I enjoyed dissecting the flowers. The reason i enjoyed this was because i enjoy doing hands-on activities. One thing i learned reminded me of when we did cell reproduction. It reminded me of when a cell reproduces with itself and it has identical off spring compared to when it reproduces with another cell to make a different looking cell. The reason it reminds me of this is because, when pollen from another flower gets on a different flower's pistil it will have a hybrid flower, apart from if a flowers own pollen falls on it's own pistil it will make a flower that looks just like it. To me it was quite interesting information.
Interactive Pea Experiment

While playing the game i tryed to see if two yello plants can make a green plant.(pea). What I came across was that the first two they give you is one yellow wrinkled and one green smooth, that made 3 yellow wrinkled and one green smooth. The first time I mixed together two of the yellow wrinkled one was yy Rr and the other was Yy Rr in the end it made the same effect yellow and one green. The second time I did this, I mixed the green with a yellow and I get all green wrinkled so then I said that green "parents" can not make yellow offspring.

Traits-Heredity

While reading the following information i learned some things. For example, i learned that humans share dna, about 99.9% to be exact. I was shocked, because people look very different from each other. While hearing about heredity, i learned that everyones parents have 23 chromosones, it forms a zygote. The zygote is made of 46 chromosomes, (2 x 23) later on in development it forms a baby. This stage in development is the reason for why one child can look like only a certain parent or a mixture of both parents. In the end i learned many things.

Current Event: Numero dos

Let me start off by saying soory for the late entry.
Can you believe that paper can be used as a batterie. Well researchers state that by using a corbon based ink on normal printer paper layers they could powere things. It was first explored years ago. First the coat the paper in the ink then they heat it so the ink is "stained" into the paper it then is rolled and can be conducted. So not only does the paper batterie save money but it's recycleable. Some people ( look at comments) believe it might not work they believe in something else.
