Must Be the Music

Maybe creating this blog for my biology class isn't the only thing I could use it for. I'm going to have way more time on my hands this summer than I have ever so I figured I would spend it dedicated to my music. So from now on I'll be posting thoughts, updates, and lyrics for my new Since the Promise blog!

DNA Lab Analysis

When we did the lab earlier this week, we focused on analyzing DNA. First, we took the raw wheat and mixed it with the hot water forming the wheat germ mixture. As the detergent was added it didn't sit at the top of the wheat mixture because it wasn't liquid detergent. We were careful not to mix it so rapidly that bubbles were not created. Alcohol was added after that. As the mixture sat, our observations were that we could see a white clear substance forming at the top of the yellow dirty orangesh mixture of the wheat, water, and alcohol. With the DNA coming into contact with the alcohol, it precipitated. The stringy collage as a result of the wheat germ soup stuff was the forming. After when we lifted the DNA out of the test tube all of the stings drained of the liquid and attached together forming a yellow faded pile of goo.

By doing this lab I learned that because the wheat germ mixture was more dense than the DNA, the DNA was able to float to the top.

The Stages of Mitosis

When we did our lab, we counted the number of cells in that part of the onion slide. The total number was 342 cells. Certain cells were at different stages and that is what the graph above shows. Four of the cells out of the 342 cells in that section were at the Telophase. In percent form, it was 6%. The same amount of cells were present for metaphase, 6%, two cells were in the middle of prophase. That is where we got the 4%. The last one was anaphase and when turned into a percent it is 4%. These were the cell phases. Interphase is when the nucleus in a cell is not dividing. Prophase is the first stages of mitosis when the cell starts breaking down. Metaphase is when the chromosomes line up along the spindle. Anaphase is when the chromotids migrate and move away from one another. Telophase is the final stage where everything is divided and surround a pair of chromosomes. The percentages help distinguish which phase takes the longest to go through. Since their were more cells in prophase, it can be inferred that prophase take the longest to go through. The period of one cell starting starts. As more cells enter that phase, less are exiting it and going to the next which is why it has a bigger percent of cells. So prophase and telophase probably take the same amount of time. Four percent of the time the cells are in anaphase. Most of the time cells are in interphase so interphase takes the longest to complete. Through the microscope we were able to observe all of these phases and identify them to create the graph. And vwalla!

RESPIRATION

Respiration is another way of saying breathing.Cellular respiration is a method that used to convert food into energy.In order to do this the cells need oxygen. Some cells use anaerobic respiration which basically means it doesn't need oxygen. An example would be when someone exercises they build up lactic acid in muscles. Respiration affects the body everyday whether we notice it or not.

Green Human Photosynthesis

Green Human project. This is an article about if humans were able to perform photosynthesis.

Enzyme Lab

An enzyme is something that speeds up a chemical reaction. When we did the activity in class, we first had the enzymes reacting normally. When the inhibitors (things that are added to slow reaction down) were added, the process did slow down because they looked exactly like the enzymes. Then the enzymes don't work the way they are suppose to. They are controlled by temperature as well as the PH level. When the enzymes didn't know which one to choose, the rate of capturing slowed down. The activity is how we showed the relation.

Metabolism

A way for our bodies to get energy is the main concept of metabolism. It changes the food into nutrients that your body can use for energy. That is what keeps our cells working properly. Kids Health says "it is a process that begins even before were born and doesn't end until you die." But it doesn't just work in humans. It works in all living organisms. The chemicals break down the sugar and turn it into energy. Some people's metabolism is fast and others is slow. This just means that the body breaks down and uses the energy faster than others. If someone gets hungry faster than others than that means there body had already broken down their food. Energy that is not used is stored as fat and that slows down your metabolism. Energy it makes the world go round.
