Reebops

Punnett squares are tables that can determine the outcome of an offspring between things like bugs, flowers, and humans. first we need the genotypes of what you are taking the genes from and form the punnett squares then put one set of genotype on the top each are alligned with the two boxes. the other goes on the right side then they sort of fuse together in the boxes.

The reason why I am doing this is because it involves the experiment we used in class to do with the bugs. it shows how we can use these punnett squares in real life to determine what kind of baby we would recieve or have.

like this. This example really shows how an punnett square is used. It may look hard to do at first but it is so easy once you get the hang of it. scientists have been able to control the outcomes of these by doing selective breeding or in otherwise choosing what things will breed with what. Cool right? so we used this for practice in class to actually help us understand things to you

Genes

Selective Breeding. Selective Breeding is the ability of man kind can choose how an outcome of a plant is. How is this possible might you ask? Well if plants can breed with plants than a great scientist thought "what if they could be selectivly bred?" So he experimented. In his experiment he made a diagram called a punnet square

As shown above. So this helped him recognize how these outcomes were possible. So he figured out how selective breeding was possible.

What really helped me understand this was the website experiments on this. When we did the experiments online it was fun and enjoyable.

Mitosis

What we had done during this week was we talked about mitosis. Mitosis is a cell cycle theat divides the nucleus into Two parts called asexual reproduction meaning that I reproduces on its own. There are for phases. Prophase, Metaphase, Anaphase, and Telophase.

In Prophase The nucleus starts to dissapear and the chromatids start to coil and fold or uncoil. Then in Metaphase The chromatids start to aline in the center of the cell. Anaphase begins when the two parts of the X's start to seperate from each other. Finally Telophase, in telophase a new nuclear membrane is formed. Then lastly we have Cytokinesis. the two new nuclear membranes start to split apart to become two cells.

over the week

What we have been learning over the past week we have been observing how organisims reproduce. We saw that in the organisims or cells there were two nuclei. That ment that the cell was in the process of reproducing it self too make two cells. When they split apart that means it has reproduce.

What my partner and I found was that there were four nuclei in one cell. Hmmm? how could that be? Well we brought it to the teacher and he said "maybe that isn't a nuclei. Maybe it is just clumps of DNA." For now we are going with that observation but we can tell until we get a further observation.

blogging about the week

Over the week we looked and studied about protein synthesis. Then we looked at the books and did a reading on the protein synthesis. We also had started to do a project about one of these four options. Photo synthesis, protein synthesis, respiration, and fermentation.

In the project we have to explain how each of the work. Anyway back to the books. We had recapped what parts of a cell do what like the mitochondria helps to respirate and cytoplasim holds everything together. Also we checked what cells were prokaryotic and eukaryotic. Then after the readings we started to work on our projects.

blog 12/7/09

What we did over the week was we talked about how and what the structures of a DNA molcule looked like. It had two double helixs with rungs inbetween. The rungs were different colors in the examples that he had showed us and we havent quite figured out why. For the homework we had to decode a bunch of numbers aand the message was
"DNA stores info just like computers''
Also with the experiment we did today it had involed the message with the homeork. Turns out that we in a way stored the directions in our heads then used it to make somthing.

photosynthesis

Over the past week we have learned the cycle of photo synthesis. It needs sun light, water, and carbon dioxide. In return it gives us oxygen and glucose otherwise known as sugar. Then we took a spinach leaf and left it in a tube with water and and put next to a light. there was no growth but there was evidence of carbon dioxide because we took a device that detected how much carbon dioxide.Then we finished up with a mini experiment using legos and made a replica of what an h2o cell is along with co2 and C6h12o6 replicas.
