unit 9 reflection

In this unit we learned about classification and evolution. Some of the themes and and understandings in this unit were about classifying groups. Also we learned about kingdoms and domains and bacteria and viruses, plants and animals. We learned about the evolution of the planet from the first organism to humankind. we learned how the different evolution of animals and the evollution of humans through out time.

I really would like to learn more about humans and how they evolved from monkeys. I would like to know how the evolution of mankind cancelled  out the tail of a monkey but kept similar features. I would also like to understand more on how different species and how they tie back to their kingdom. How does the human evolve into something so different then the chimpanzee? I wonder Earth really did start from a virus.

In this unit my presentation was on the banana. For my presentation I feel like I did really well on the content and information on it. but the one thing that I really struggled with was keeping my eyes up and interacting more, even though it is difficult for me to speak in front of crowds and have a little bit of stage fright. For future presentations I will work on talking more in front of people and just pretend that I'm talking one on one with someone.   https://docs.google.com/presentation/d/1ZMW-2XkVaMr7krdXsQiE9QAxLWi_79T8vK70JzP6P-A/edit?usp=sharing

geological timeline Reflection

In this Reflection, we were asked, "describe three major events in Earths history". I found that 3 major events that have happened are the dinosaurs and how they lived in this planet when all of the sudden a meteorite came out of no where and created a mass extinction killing the Dinosaurs and other species as well. Another event is when marine life went on to land which help create land animals. Another one includes the different evolutions in this planet for example monkey to human, wolf to dog and many more. This data shows 3 major events overtime and how it helped develop our world today.

Earth is approx. 4.6 billion years old. Since the beginning of time on Earth when the Earth was covered in rocks has evolved so much overtime. Now there are animals, oceans, plants, electronics, and many more. One thing that surprises me the most is that Earth is really old, yet humans have been on this planet for so little compared to other species and the time of how old Earth is. Homosapiens are around 4 million years old which is only 0.00086956521 or 4/4,600 of Earths age.

As humans we have had such a huge impact on Earth both good and bad. The good things are is that we have farmed and know how to survive and also we have had a industrial revolution and a technological revolution. The bad things is that we are causing global warming and are killing our planet.

I inly have a few questions that are on my mind, which are, What came first in time Fruit or vegetables?  Also, When the meteorite killed all the dinosaurs, how did the meteorite affect the Earth otherwise? Did the Earth have many Earthquakes? Were there tsunamis?

Unit 8 Reflection

In this Unit, Unit 8, we were taught about evolution. The major themes and understandings to help us better understand evolution was Natural and Artificial selection, the 4 different types of isolations, being reproduction isolation, geographic isolation, behavioral isolation, anat one extremed  temporal isolation. We were also taught about the different selections, being Directional selection which favors phenotypes, stabilizing selection which favors the intermediate phenotype, and disruptive selection which favors both extreme phenotypes.

In this unit I would like to learn more about why a species ant reproduce with each other after going through geographic isolation. I have one unanswered question which is if earth is 4.6 billion years old then how old is the universe? I wonder what the max of how many times a species evolved before the species went extinct? An example of when I was assertive is when I beat this guy in basketball and he still said he was better then me and was really annoying me and making me angry and instead of saying your the worst and stuff like that, all I said was ok maybe next time you will beat me ad then I just walked a way. But I can definitely be more assertive by being more respectful when angry.

Hunger games final Analysis

1. In this unit we did a lab that represented evolution and growth over a period of time. This lab simulated over time how populations survived and reproduced and how they evolved.

2. The knucklers were the best for capturing food because they didn't die off and they reproduced a lot.

3. The population evolved because the different birds and their population size either increased or decreased. The knucklers evolved the most because they survived the most and which meant that they reproduced the most giving opportunity for their species and other species to grow. For example knucklers population size was the most at the end with a total of 14 while the pinchers had 6 and the stumpy's had 1.

4. Year one, instead of having all food their was plastic which really made it random and changed the population size of everything. Also the location of all the food and if it was spread out or not was random.

5. Yes it would have been different. I feel like if the food size was differnt it could have really effected how the population grew and ate. It would have been easier for some and difficult for others deoending on the bird itself. THis could have happened in nature like if a animal can't eat another animal anymore casue it went extinct then they woud have to try a differnt sized animal which would be differnt and more difficult.

6. THere would definetly be a difference if there was incompoleyed dominance. THere could have been a huge change in the fact that if there was less knucklers to start out with and more stumpys and different amount of food it would have a lot of change.

7. The relationship between Natural selection and Evolution is that without natural selection then evolution would change. natural selection plays a huge part in evolution because animals adapt naturaly to the different areas that atural selection gives.

8. Individuals will survive by having  job and paying for their food and will reproduce by having a mate that they will live with.

9.In life plants and animals evolve. Evolution occurs with both phentotype and genotype because reproduction changes the genotyoes of the new born and the phenotypes are the physical characteristics.

10. I have no new questions that we have already learned

Unit 7 Reflection

In this Unit the main topic was about Ecology. Ecology is the study of how organisms interact with one another in a Ecosystem. In this Unit we learned the different levels of organization and how those levels contributed in the world. We learned about food chains and food webs and how Primary producers are at the bottom of the food chain. We also learned about populations an d hoe each population can reach a carrying capacity. WE also did some worksheets in class and also a project which was based on a ecosystem somewhere in the world and we had to list the food web its threats, the animal and plants, and what we as humans do to help. WE recently watched a movie in class called Bag It which was a movie about plastic. It told us how plastic is used inour everyday life and is really harmful to the environment. It also tought us that if we don't recycle it it would be even worse and becaome a manmade toxic called doxinide. It also said the different types of percentages in what gets recycled of the stuff tht we think is recyclable. THe lowest I saw was 0% and the highest I saw was around 24%. It was amazing the percentage of plastic that doesn't get recycled which ends up harming our environment.

I want to learn more about plastic and dit's chemicals and what species have gone extinct because of plastic. The thing I still have a question on is where does all the plastic go because if allthe plastic goes in the dirt then where does that dirt go? I wonder how is plastic really that usefu when it is harming our environment so much.

We recently did a project on enviroments and their ecosystems and for my group we found out some really mid blowing information. Are project was based on the coral reefs in Fiji. We found out that Fiji has a lot of threats where most of them are because of man made activities. The thing that went well in our project was how we collaborated with one another and helped each other out in areas we needed help or wanted help. We also came to agreement on many things and were all happy about the outcome. Our collaboration was good. We talked about everything that we were doig and diciussed it woth out group members to better understnasd the project and the Fiji Coral Reef. In my "test" I got results back theat told me I was  alittle aggressive and a little passive.

unit 6 reflection

In this Unit we learned about Biotechnology. Biotechnology is a very complex science that has been going on for centurys. It hasn't just started in the 21stcentury. Biotechnolgy includes genetic engineering which is a procces of cutting and pasting DNA strand strands together and recombining. We also learnedabout gel electrophoresis and pGLO. We learned about how biotechnology is how we we made cuires for diseases and sicknesses. WE learned about the technologies to Biotechnology and also bioethics and the explanation which also included recombinant DNA. In this unit my setbacks were that I my group wasn't very collaborative and I didn't really collaborate as much as I should have. But my successes out reach my setbacks. In this unit I did really well on my labs and blog posts and did all my cfus and got full credit on my vodcasts. In this Unit I have really done my part and gogt to know more information. I truly believe I focused more in class aswell.

In class we did two different kinds of labs.The fist on was a gel electrophoresis lab where we used electricity currents and candy dye. While the other lab is called a pGLO lab which was a two day process where we had bacteria and would use pGLO to see if it would glow green and the end. Because of these labs I learned moreabout the topic itself and learned more from it. Labs help me understand more because I'm doing myself and with others in erson up close.
 

I want to learn more about genetic engineering. there is really one think I don't quite get and that's recombining DNA. I wonder how genticengineering can help mankiinf and strive manking to greatness.

For my nw year goals. I followed them like planned and I payes attention more in class and wasn't talking as much and did my homework and didn't procrastinate.

pGLO Lab

pGLO Observations , Data Recording & Analysis

1.

Obtain your team plates.  Observe your set of  “+pGLO” plates under room light and with UV light.  Record numbers of colonies and color of colonies. Fill in the table below. Plate Number of Colonies Color of colonies under room light Color of colonies under   UV light - pGLO LB 1 huge colony faded white faded white - pGLO LB/amp 0 white white + pGLO LB/amp 10 white white + pGLO LB/amp/ara 15 bright white faded green Neon green

2.	What two new traits do your transformed bacteria have? one trait is that it is resistant to ampicillin the other is that it glows green under UV light.
3.	Estimate how many bacteria were in the 100 uL of bacteria that you spread on each plate. Explain your logic. in the trillions because one e-coli is one micrometer cubed. There are 100 microleters on a plate. that totals up to an equal to 100 trillion e-coli
4.	What is the role of arabinose in the plates? The arabinose is a sugar which makes the e-coli glow a neon green color
5.	List and briefly explain three current uses for GFP (green fluorescent protein) in research or applied science. There have genetically engineered fish that are able to glow green under flurescent light. scientists have made away to make glowing genes that made a pigs nose turn neon orange scientists have made away to have glowing chickens
6.	Give an example of another application of genetic engineering. scientists have made a bionic chip which hooks up to the nerve system in the mody os small animals and are able to control them.
