Transformation lab

In this lab we tried to see bacteria Transform and the data recorded on these worksheets

Evolution and selection

In this lab we talked about Evolution and selection and how it would be effected 

skull lab

In this lab we looked at various skulls and did a worksheet about what kind of skull or what type it was and the traits it had

DNA Work

Baby Lab

In this lab we had an experiment with a partner we had to compare our features with each other and write who had what and if it was different one person would write big x and little x like so Xx and if the other person depending on the result would of had XX or xx it all depends on what its asking on features and how you look

This is the data table if we had opposites on a feature we had to flip a coin if it was heads it would be the mothers trait so XX for the first feature if it was Xx it would be the fathers trait again it all depends on the person you partner up in my case i partnered up with someone who has the same traits as me so much of our features were the same on the data table

As you see this is what i drew and our baby came out rather ugly i drew the mustache because my partner is hairy so as the baby grows its most likely going to have a lot of facial hair we both have brown hair and eyes but i have curly hair he has flat hair and we both have ovaled shaped heads and not so bushy eyebrows I'm just not good at drawing

Here is my genetics notes

mitosis and meiosis

Meiosis

* Requires two nuclear divisions
*Chromosomes synapse and cross over
*Centromeres survive Anaphase 1
*Halves chromosomes number
*Produces four daughter nuclei
*Produces daughter cells genetically different from parent and each other
*Used only for sexual reproduction

Mitosis

*Requires one nuclear division
*Chromosomes do not synapse nor cross over
*Centromeres dissolve on mitotic anaphase
*Preserve chromosome number
*Produces two daughter nuclei
*Produces daughter cells genetically identical to parent and to each other
*Used for asexual reproduction and growth

Cancer

Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die and new cells take their place. 

When cancer develops, however, this orderly process breaks down. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. These extra cells divide without stopping and may form growths called tumors.

Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive one important difference is that cancer cells are less specialized than normal cells. That is , whereas normal cells mature into very distinct cell types with specific functions cancer cells do not. This is one reason that, unlike normal cells, cancer cells continue to divide without stopping 

In addition, cancer cells are able to ignore signals that normally tell cells to stop dividing or that begin a process known as programmed cell death, or apoptosis, which the body uses to get rid of unneeded cells

How the cell wall is and how stages of cancer break it and go all over the body
