We did an experiment with cockroaches. We wanted to see whether the cockroach would react to magnets. We put it in a paper towel and made it crawl down to the magnet and it just stoped we changed the metals and it crawled right out and over it. So it dose react to it

Did you know that cockroachs can survive in more radiation than we humans can. They can also fly if they have wings but it depends on the type.

I do not know much about cockroach s but they live all over hawaii and Madagascar. Darth Vadar's head was based off the cockroach head. What I want to know is how their body works.

The Hot the Cold and the Avrage cacti! (plant expiriment)

My plant experiment was how the tempeture afects cacti in the dark. We had one in the incubator at body temp wich is 96.5 ferenheight. We had another in the fridge at the dessert night temp wich is about 45 ferenheight. And one room tempiture wich is 68-72 degrees f. The room temp did best but it got some light because otheres put theirs in the closet as well and it got more air circulation. The cold did the second best and it was preaty much a perfect experiment. The one in the incubator was cooked because it was hotter than it is used to.

43267.5 pounds that is how much carbon dioxide is sent into the air when i get my lunch. It was a cheese burger whith jam and bread i also had a bannana, yogurt, and a glass of orange juice. The total miles to get that food was 11,538 miles. To get the pounds of carbon you multiply 3.67 by the total mileage. It is preaty horrible just for one lunch.

Diversity
Article posted March 1, 2012 at 06:26 PM GMT •
comment • Reads 705

|
The reason why offspring that result from sexual reproduction are likely to have more diverse characteristics than offspring that result from asexual reproduction is because there are some traits that are more domonant than other traits like oval faces are more domonant than square faces. It is a confusing subject but once you have it down it is easy. The reason for this is that the cell goes throuh the phase mitoesis and it has both the oval and square face traits and wichever is more domonant comes out.

In our lab we swabbed different areas around our school looking for bacteria. my teamate and I predicted that There would more bacteria in the toilet. we were correct there were more bactiria in that area. there were more colnies and they were the largest we located in our pitri dish. We had one area and that was we cracked the augor. We observed after preparation of 24 hours and 48hours there was nothing. Only the toilet and water fountain colneis had bactiria in the fountain there was a very small one but nothing else. The sink Had no evidence of bacteria. Bacteria is every where. If we had observed for a longer time we might be able to see our bactiria grow more.

Mitosis

This is the prosess of mitosis:
The growing part of a mitosis is the longest period. During the cell cycle the DNA duplicates, and the protiens are producing. The cells will also grow in size. This is the first step called the interphase.
in the interphase the cells start to duplicate which then makes 2 cells during this stage the proteins are made.
in order produce the 2 sister cells the DNA in the cell MUST also be multiplyed. This occures in the synthesis phase. The chromosome splits into two twin chromosomes.The cell mom tells the daughters that they need to live.
These are the steps indevidualy (much better):
Interphase: the longest period . The DNA duplicates and the cell divide.
Prophase: In this stage the nucleolus starts to fades. The nucleolus then starts to meet together into the new chromosomes.
Prometaphase:The nucleolus envelopes break down. This stage is where the protein is mixed together and the 2 sister cells apear.
Metaphase: preasure is applied by the spindle fibers align all chromosomes in one plane at the core of the cell.
Anaphase: The spindles fibers are minimised and the 2 daughter cells are torn apart. they then travel to the cell pole.
Telophase: The daughter cells get to the cell pole and the spindle fibers that pulled the sister cells apart go away.
Cytokinesis: Contactile ring pryes the cell into 2 daughter cells. Then the new cytoskeleton is reorgonize by the microtubules and then they are returned to the interphase stage.

Plant cells v.s. Animal cells
Article posted January 27, 2012 at 03:15 AM GMT •

I have studied both the plant ant the animal cells and I have found some similarities and differences between them.
These are some things that both types of cells have:
Plasma Membrane, a Nucleus, a Nucleolus, Mitochondria, Ribosomes, Endoplasmic Recticulum, Golgi Body, Peroxisomes, and Microtubles
These are some things that only plant cells have:
The shape of a Plant Cell is more square like, Cell Wall, Chloroplast and Vacuole.
These are some things that only animal cells have:
The shape of an Animal Cell is more of a circle, Centrioles, Flagellum, and Lysosomes
Those are some similarities and differences between plant and animal cells. Thank you for reading!

While my group was looking through our microscope we saw a lot of paramisiam they moved a lot and they also ate. What we did not notice that the blobs all over the place were the things we were looking for, amoeba they did not move at all but our seience teacher taped one and when it was fast forwarded it moved all over the screen

My New Opinion on Global Warming
Article posted October 31, 2011 at 01:26 AM GMT •
comment • Reads 1235
|
|
We as humans create many things that destroy our atmosphere such as industries, cars, heating homes and cuting down trees. This is only a little of what we are doing. We create too many green house gasses. If too much CO2 gets into the atmosphere then it will lead to great floods, droughts and more spreading of infectious diseases. It will also increase the inensity of heat waves that come down to earth.
The website(http://www.causesofglobalwarming.net/the_facts.html) states the folowing facts and myths:
A myth: Global warming is just part of a natural cycle. The Arctic has warmed up in the past.
A fact: The global warming we are experiencing is not natural. People are causing it.
A fact: Actualy, water vapor traps more heat than CO2, because of the relationships among CO2, water vapor and climate, to fight global warming nations must focus on controlling CO2.
1. Can people do something now to fix the global warming part of climate change?
- Yes, based on reading many diffrent articles on the internet, I think that there is somthing that we can do to help slow-down or stop global warming from getting out of hand. Here are a few things we can do:
- We can start planting more trees for every tree that we cut down(because cutting down trees is a buisness and most won't quit doing it).
- We could pull our minds together and find more efficient ways in every day life such as better electric cars(from what I've herd most electric cars suck).
- We could make more homes using solar power or wind powered electricity.
These are great ways to help put a stop to global warming.
2. Should we do something now to fix global warming? Why or why not?
- Yes, even if we are late we still have time to fix it.
- If we don't:
Global warming is having a significant impact on hundreds of plant and animal species around the world. According to:(http://www.causesofglobalwarming.net/the_effects.html) "Clearly, if such ecological changes are now being detected when the globe has warmed by an estimated average of only 1 degree F (0.6 C) over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F (6 C)."

Living Qualities

Well, what qualities confirms that something is alive? In my opinion something that can repopulate is alive. If it can die then it was once alive. If it can breathe, consume, and if it can grow old it is alive.

My class did an experiment on 5 different things, red sand, yeast, orbies, radish, and brine shimp. We used these organisms in 3 different environments, H2O, sugar water, and salt water. The Environment affects organisms because organisms need a certain environment in order to survive. The seeds didn't grow in the salt water because the seeds need fresh water like the regular H2O or the sugar water. The salt water killed the seeds because it did not get the correct nutrients. Therefore, the seeds were not able to grow. Some of our living organisms appeared non living because it didn't show any sign of life like breathing or movement. Like the seed, brine shrimp, and yeast, all of them did nothing in our tubes. They need time to grow in the environment. Organisms need to to be exposed to the right enviroment. Like seeds need fresh water to be able to grow. The brine shrimp appeared non living even in the salt water. For some reason Domanic touched them when the instructions told us not to. Thats all for today kids!

My opinion on global warning

I think that humans can help global warning but cannot stop it because it has already happened. If we could stop it the north and south pole would probably slowly remake themselves. I don't think that global warming can be stopped because it has already started.
