Thoughts on Data Analysis 2017

1 – Statistics play a very important role in our day to day lives. They give us insight on research, and a general view of a certain group.

2- Statistics give us a perspective of large groups and a possible view on the future.

3 – People know how to hide bias very well, and it can be hard to determine bias and the information given.

11.1 Factors Influencing Data Collection

When I first read the article, I thought that it was a great form asking students’ which shirt they would purchase.

After learning about influencing factors, I now think there was bias influencing the shirt the students’ would purchase.

In the future, when reading and interpreting survey data, I will analyze the question being asked, and the information and product being given.

Genetic Mutation Story

 

Part 1:

Hello! I am esophageal cancer and I first appear in the cells inside of my host’s esophagus. I have two closer relatives, Adenocarcinoma and Squamous cell carcinoma. The treatments currently available injures both me and my relative.

Humans cannot notice me until I manage to grow nice and big, blocking entrance to my host’s stomach. Sometimes my host can experience weight loss, painful swallowing, pain in the throat, heart burn / ingestion tiredness, loss of appetite and even nausea and vomiting.

Humans currently try to find me by using blood tests, examining the count of blood cells and seeing if anything is abnormal. They have also tried using imaging tests to see through my host’s esophagus, scanning for tumours.

If humans manage to find me, they try to kill me by surgery, but because I’ve already blocked off my host’s stomach, my host will need to have a feeding tube to stay healthy before the surgery, because it is very hard to recover form esophageal surgery.

Part 2:

I had to research the effects, treatment, cancer growth and the recovery process to create my story.

I used digital diagrams to learn about the effects of esophageal cancer through this project.

I first searched for the effects esophageal cancer, and then investigated the consequences and how it developed.

I used cancer.ca, hosted by the Canadian Cancer Society, on of the leaders in Cancer research across the world, and used EasyBib.org to cite my source.

I learned about the development and different treatments of a cancer I had not known before, and thought that the story went pretty good overall.

Science DNA Lab

Relating chromosomes, DNA and genes

Chromosomes are double helix structures that is formed of DNA and proteins. Chromosomes are found in the nucleus and they contain and organize genes.

The pieces of the lab

Licorice – Phosphate Backbone

Marshmallows – Bases of the DNA.

Green  (G)uanine

Pink – (C)ytosine

Yellow – (A)denine

Orange – (T)hymine

Without mutations, A-T, G-C are always bonded together.

Understanding the structure of DNA

It created a visual and physical structure for me to personally learn the structure of DNA.

 

Observing Cells Lab

Animal Cell:

The animal cells look like small popcorn kernels with a dot in the middle.

The cytoplasm and the nucleus is visible.

 

Plant Cell:

The plant cells look like the scales on a fish.

The cytoplasm and membrane are visible.

 

General Questions:

 

Finding the differences in animal and plant cells

  • Plant cells have much more visible membranes.
  • Plant cells have more of an oval shape.
  • Plant cells are larger.
  • Animal cells have a visible nucleus.
  • Animal cells have a more round shape.
  • Animal cells are smaller in size.
  • Animal cells move easier.

Why methylene was important in the animal cells

The methylene was used to highlight bacteria and DNA in the animal cells.

Reflection

I’ve learned how to properly use a microscope, when to use methylene and how to extract animal cells from ourselves and viewed the different visible parts of the animal and plant cell.
