Symbiotic Relationships 10/12/25



   This week I learned about what a symbiotic relationships are. Because my science class got a paper to do with Ms. Johnson about symbiotic relationships. Symbiotic relationships mean mutualism, commensalism, parasitism and competition. But my class only learned about mutualism, commensalism, and parasitism. Mutualism is when both organisms benefit, commensalism is when one organism benefits but the other organism doesn't get hurt, and parasitism is when one organism benefits while the other organism is getting harmed. An example of mutualism is splitting money in half, both organisms (  humans ) benefit because one organism is getting money and the other organism is too. An example of commensalism is a bird having a nest on a tree the bird is benefiting by getting a place to live/stay but the tree isn't getting harmed. An example of parasitism is lice in your hair the lice is benefiting by getting to have food but the human is getting harmed because it is losing blood.

   Another thing I learned is why symbiotic relationships are important. Symbiotic relationships are important because the world could over populate without it. Also because without symbiotic relationships then the world would lose organisms. My last reason about why symbiotic relationships are important is because then humans might die.

Systems In a Human Body Info Paper 10/15/15

Friday and Monday we were writing down the definitions of (I believe) organelles that are part of the urinary and digestive system. Here are some examples of some of the organs my class had to write down the definitions for, the esophagus, the pancreas, the liver, the small intestine, and the large intestine. One thing that I forgot to add is that there was one other paper that had the definitions down for my class because I did not want anybody thinking that my teacher would make us write the definitions on our own out of the blue. The way we knew the definitions was because on Thursday or Friday I forgot which day any ways my teacher showed what every organ that we had to write the definition for what each organ did in order. But the fun part was she assigned every single person in my science class an organ to make it fun. What also helped was that Ms. J went over the answers with my science class also she allowed ...

Chemistry Mastery Quest 2 Regrade

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

Plate Tectonics 3/10/18

Image
Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges...
