What I Think Are The 5 Most Important Things I Learned In Math 9

How to multiply and divide fractions

I think that multiplying and dividing fractions is one of the best things we learned because it sets you up for life if you work in trades.

you multiply a fraction by going straight across so top times top and bottom times bottom and that is the answer. you divide fractions bye flipping the second fraction so the top is now the bottom and the bottom is now the top and than you flip it to a multiplying fractions.(look at inserted photos)

   

 

How To find the surface area and area of a square

i think this is important just like multiplying and dividing fractions because it also sets up you career in trades.

you find the surface area of a 3D shape by fining the area for all the sides and adding them together. you find the area by lenght times width time height (look at inserted photo)

 

How to graph points and find what the linear equation is.

it is super important because you need to know how to to graph because if you need to make a graph for work to see yow much your sales have gone up or down. also you need to know how to find the linear equation in between the numbers.

you find the linear equation by  finding out how much the y axis goes up bye or down bye. so if the pattern went 1,6,11,16 it would be 5 and than now you have to find a number that will make it true so 1×5= 5 – 4 = 1 so the answer is 5x-4

how to solve for X

solving for x is super important because its just a good thing to have in your back pocket so if it ever came up you would know how to do it.  so if you had a question of 10x-6=4 you would go + 6 on both sides of the equation to make a zero pair so than that would make the equation to 10x=10 than you would divide 10 from both sides so the final answer would be x=1

 

How to add and subtract decimals

this is very important because you need to know how much wood for a project or for me wear I work I need to now how much fabric i need to get for the roller shades I am making.

you add or subtract a decimal by lining up the numbers and the decimal (look at inserted photo.)

Stem Cell Project

 

 

Leukaemia and Stem Cells

 

Stem Cells: Stem cells are cells that can be modified and can be used for any cell application.

One application that stem cells can be to replace bone marrow, many people dont understand the importance of bone marrow in are body, without it we would die. The bone marrow in are body produces red blood cells, white blood cells and platelets. When somebody gets leukaemia the bone marrow produces an abnormal amount of white bloods cells. A low amount of white blood cells can cause body aches, high fatigue, easy bruising and a increase in infections.

We can harvest stem cells from the cells inside bone marrow. Now doctors like to harvest stem cells from blood instead of the bone. But more recently scientist have been looking at way to use stem cells to help treat bone marrow related diseases like leukaemia. Basically there are 2 main ways to treat leukaemia through stem cell transplant.

  1. They found that you can take the cells out of your bone marrow and then they will be freezes for a certain amount of time. In this time period the patient receives high doses of radiation or chemotherapy. After the cells have been frozen they will try and kill all the leukaemia infected cells and then they will be returned into the patient along with the stomach stem cells that replace the cells that were lost.
  2. The other way of stem cell transplant is to take cells from another patient (usually a donor) that are a close match to the leukaemia patient, then those cells and put into the patient and they begin to make blood cells that combat leukaemia cells. So basically its a immune system against your immune system.

There are some problems with these treatment like for example its hard to differentiate leukaemia cells from good cells and that the cells taken from someone else must be an perfect match and it can be hard to find someone who is willing to donate. Another big problem are the short term side effects that come from these transplants like nausea, vomiting, loss of appetite, mouth sores, and hair loss. The long term side effect are even worse and include loss of fertility, damage to lungs, cataracts and the potential for other cancer to develop years later.

There are things that need to be perfected with these translate but in the near future I do believe we will see them perfected. For that very reason its still not legal in Canada and the United States to do these treatments but soon to come, we could see leukaemia disappear  from earth. All we need is more research.

Refection:

This project really pushed the whole idea of ask and acquire concept by making us research what we wanted to do. It was interesting to learn about how stem cells could help with the thousands of people world wide suffering from leukemia  and it was a lot of fun doing this project.

Cell Analogy

Cell parts and body parts comparison

Cytoplasm : Cytoplasm is like the blood in a human because its a Gell like fluid that’s made up of salt and water and your blood is made up of 92% water and .9% of salt.

Membrane: The membrane acts like a wall or a lining to protect the cell from its outside environment, the skin also acts as a wall to protect us from certain thing like the cold and the sun and some diseases.

Nucleus: The nucleus is just like a human brain they both tell the rest of the body what to do. It’s the driver in the car.

Endoplasmic reticulum: The E.R is like your digestive system, it gets rid of things in the cell and releases them outside of the cell, same for humans.

Lysosomes: They break down and digest certain molecules in the cells and sends them to the E.R, the intestine breaks down waste and send it to your… yah.

Ribosomes: Ribosomes manufacture proteins that are essential for the cell. Funny enough the liver actually does the same thing, creates vitamines and proteins for the blood.

Golgi body: The G.B transports different packaged substances for the cell. The blood stream is similar but different compared to the blood stream, it moves blood around for the cell.

Vacuole: The stomach in a human holds certain foods and preps them to go through the rest of the digestive system. The vacuole does half of that and only stores the food for the cell.

Mitochondria: People say that the mitochondria is the power house of the cell. Are muscles allows us the have incredible strength similar to the mitochondria.

And that are cell comparison to the human body

Life cycle of a cell

This is the life cycle of a cell

  1. Interphase

Interphase is the longest phase a cell goes through and can take up to 20 minutes, in this phase the inner white circle is the nucleus wall and inside you can see chromatin (pink fibres) and the nucleus (red fibres). The centrioles have yet to form the spinal fibres.

 

  1. Prophase

In prophase the chromatin (multi coloured fibres) is becoming chromosomes within the cell nucleus wall (inner white circle) thats in the process of disintegrating. Depending on what phase of prophase the cells in the spinal fibres are either done or in the middle of forming.

 

  1. Metaphase

Many people like to remember metaphase as the middle phase, not only is it the middle of mitosis but most importantly the chromosomes (multi coloured fibres) are in the middle of the cell. The spinal fibres (pink fibres) start to latch on to the middle of the chromosomes.

  1. Anaphase

People like to remember anaphase as the away phase because the chromosomes are being pulled away from the middle by the spinal fibres.

  1. Telophase

In telophase the cells begins whats called cleavage while the cell begin its jump into cytokinesis, the nuclear membrane is starting to reform around the chromosomes that starts to become stringy.

And that the start and finish of mitosis.

Double Helix

 

This is are DNA piece. DNA is the code for who you are, it creates a copy of its self called RNA and it moves out of the nucleus to the Ribosome and using the RNA, the ribosome creates proteins. What you’re seeing is me and Ethan’s attempt at trying to replicate a DNA molecule, if you look at the DNA its made of different amino acids, 2 on each side. A RNA is the same thing but cut in half.
