1. You need to know your blood type in case you need a transfer, and you have to make sure you receive the right blood. If you don't, your blood will clog and you will die.

This is what I noticed about the simulation:
Then we had to try and make a hypothesis that would allow us to correctly predict the kinds of peas that would be born when we breeded certain peas. My first hypothesis is that if you breed two plants with the same texture or color together, all the children will be the same texture and color. These were the results:
Parents: yellow smooth, yellow smooth
Children: Green smooth, yellow smooth, yellow smooth, yellow wrinkled
My next hypothesis was if there is at least one Y, it will be yellow. If there is at least one R, it will be smooth. If it's yy it is green, and if it's rr it will be wrinkled. Another hypothesis I had was that there will always be at least one exact copy of one of the parents among the children. These were both proven.
Parents: yy RR, yY Rr
Children: yy RR, yY Rr, yy RR, yY RR
We know now that all children will be made up of some combination of their parents' DNA. At the end of the period we figured out the hypothesis. Finley said we would talk about it the next day.

9) Cytokinesis I- Cytoplasm divides, 2 daughter cells are formed.
Today we split up into to groups. There was one group that completed page 97 in the textbook. Here are the questions.
1. How long does growth phase of the cell cycle take? A. 1 hour B. 3 hours C. 8 hours D. 10 hours.
2. How much time does the cell cycle spend in interphase? A. 1 hour B. 10 hours C. 21 hours D. 22 hours
3. What is the total length of time it takes for the skin cell to complete one full cell cycle? A.10 hours B. 18 hours C.21 hours D. 22 hours
4. What phase of the cell cycle takes about 8 hours? A. DNA replication B. Mitosis C. Growth D. Preparation for cell division
5. Suppose another type of skin cell takes 44 hours to complete one cell cycle. If all of the phases are proportional to the length of time shown in the diagram, how long will the preparation for cell division phase last? A. 3 hours B. 6 hours C. 10 hours D. 20 hours
6. According to this diagram, what is the second stage in mitosis? A. Prophase B. Metaphase C. Telophase D. Cytokinesis
Then we moved to the next station and went over the worksheet labeled Examining Cell Division. Here are the answers
1. It needs to grow to get more water.
3. You can see some cells about to split and some cells have two nuclei. Also the chromosomes are in weird shapes.
4. Results may vary.
If you people have any questions ask Mr. Finley or leave a comment and hopefully I'll be able to answer.
Next we looked at 4 line graphs in which the x-axis was temperature, and the y-axis was the rate of metabolism. One was a "U" shape, one was straight, one going from bottom to top then plummeting, and one from top to bottom. The 1st question he asked us was which showed change. All but the straight one showed change because both varibles must be adjusted in order for it to be "changed". The 2nd question was which one showed the path for cellular respiration. This was the one that went from the bottom to the top because it shows the correct path for cellular respiration. Next Finley filled up ballons with different temperature CO2 ballons.
Red- Super hot
Yellow- Medium temp/warm
Green- Mix of yellow & blue
Blue- Super cold
After this he apologized for cutting our quiz time short and everybody got them back, unmarked. We had the remainder of the class to finish our report. Finally, the class was over. Do your lab report!!!Brendan Turner
Today is our second day of experimenting with Elodea. We are also using a light source. We are testing how light affects photosynthesis. Instead of using a Co2 tablet, we are using baking soda for CO2. There is tape on the table, and we put the light source at the end of the tape. The tape is already measured.Then you put the elodea that is in the test tube, on 10 cm for 4 minutes. After 4 minutes my table's Elodea had no bubbles coming up from the cut part of the Elodea. Our problem was that that the baking soda did not dissolved yet. It was it still at the bottom of the test tube. After the second time we tried the experiment on 10cm we got 3 bublbles. Then we started on 20 cm and we got 2 bubbles.
R.R Period 8
1. According to your notes, what is the equation for photosynthesis?
6CO2 + 6H2O yields C6H12O6 + 6O2
2. Where do plants get the CO2 for this process (what organisms release this gas) ?
They get carbon dioxide from all living things (Pants also breath oxygen and release carbon dioxide. They only need carbon dioxide for photosynthesis, but they still need to breath.)
3. What organelle in plants is responsible for photosynthesis (producing food) ?
The chloroplasts are responsible for photosynthesis in cells.
4. What is the pigment found in this organelle that absorbs light to power photosynthesis?
It's the chlorophyll.
5. If a plant were under water and was photosynthesizing, what gas would be visibly bubbling from the plant?
6. The 2 experiments can vary as long as it tests the two things efficiently. Look online to see what you have to test.
We also went over the experiment. It is in the packet that contains all the questions that were just answered in this blog. We just revised it a little. First off, we have to find the mass of the sodium bicarbonate. Also, we have to add 20 ml. of water to keep the experiment controlled. For today's homework, you have to read the experiment until you can do it without looking at the sheet. You also have to write a prediction on it (Remember: A prediction is not a hypothesis! Look at the syllabus for help.)
Here is a video for photosynthesis (has some things that are hard to understand, but won't disrupt main point of video and won't have to be learned for class): http://www.youtube.com/watch?v=mYbMPwmwx88
