Summary

In human cells, there are 23 pairs of chromosomes meaning 46 chromosomes total. People get 23 from one parent and the other 23 from another. Chromosomes can be found in the nucleus of cells. They are made of DNA, or deoxyribonucleic acid, which is the instructions for making us. Segments of DNA is called genes. Your traits, come from your genes. Genes can also be modified. Lots of foods are actually genetically modified, they are known as GMO (genetically modified organisms). 

SP2 Developing and Using Models

I developed a model this week when I created and tweaked my superhero automata. I also developed a model when I worked on my super villain nefarious papers. I had to draw four models about the original and nefarious of different body systems and organs. In addition to drawing these models, I wrote a short paragraph about the function of the normal and nefarious, how it changes from one to another, and more. In addition to this, I started creating a giant model with all of the information and papers from this superhero unit and began assembling it into one poster.

XCC: Structure and Function

The structure of the eye in my supervillain is what gives it is supervision or ability to see (well). Compared to a normal eye, the structure of the nefarious eye includes a larger lens to allow more light into the retina as well as a thicker retina. A thicker retina means more photoreceptors which will improve my supervillains vision. Photoreceptors are the cells that actually allow us to see everything around us including the shapes of objects and color. This idea was based off cats eyes. Cats amazing vision comes from their larger number of photoreceptors. They have around 6 times more than humans do.
