This week we were making analogies to cells after we finished watching a video clip. The video stated that people live on streets and streets are in villiages/cities, cities are in countries, countries are in continents, continents are in the earth, earth is in our solar system, our solar system is in our galaxy and our galaxy is in our universe. This all is telling something. These are all layers into creating our universe. This related to our cells and how they are just made up of layers. By knowing this information we can now make analogies and compare everyday things like a school and a hotel building to a cell. Wedo this by taking a specific part like the foundation of a building and calling it the cell wall or membrane since they both surve the same purpose.

awesome alex!
This week was all about Photosynthesis and Fermination. First photosynthesis is just like a huge cirlce along with respiration. From the chloroplast to the mitocondeia produces energy (sunlight and carbohydratrates), water (H2O), oxygen
(O2), and carbon dioxide (CO2). From the mitocondria to the chloplast produces energy, H2O, O2, and CO2. From this you can see the cycle that is being shown. Along with respirationa dn photosynthesis, if animals and plants are both part of the respiration cycle if all animals dyed than something would get messed up. Animals inhale oxygen from the plants and then exhale carbon dioxide. Then the plants give off oxygen so WE can breath and vise versa(only with carbin dioxide). Since this is a cycle niether species would be able to get back that oxygen or carbon dioxide to keep the cycle continuous. Fermination is respiration without oxygen. The reactants of fermination are glucose which are sugar, and the products are carbin dioxide, alcohol, energy and for animals lactic acid. We also did a fermination experiment.
First to see if when we put reactants to fermination, yeast and sugar, and water, into the test tube we would get the smell of alcohol and carbin dioxide would be "ehaled". To tell if there was carbin dioxide being exhaled we put a balloon over the top of the test tube to see. Our results were positive to our first prediction!
Lastly we learned about DNA. DNA is just your parents dna mixed together since no to people have the same DNA except for twins. As we learned DNA is not a cell beacuse it is made up of cells. I think that DNA is formed into a long stringy form because DNA is made up of a bunch of cells, and once they all come together they form this type of formation. :)
