What Happens Next Caitlyn Smith I woke up early one day. The cave was dark and I could not see. I went outside to see if I could find mother‚ but she was nowhere to be found; I guess she went off somewhere without telling me. I’m looking around after just waking up and I see this creature. I don’t know what to do. He comes closer‚ what am I supposed to do? I saw him running towards me and I started getting scared. He grabbed a stick and threw it towards me as if to warn me that he was

Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

Strontium Manganese Oxide Introduction The ternary inter oxide SrMnO3 was first characterized by XRD by Negas and Roth []. This perovskite type inter oxide crystallizes in the hexagonal form with the space group P63/mmC(194). This inter oxide is of considerable interest to materials scientists owing to its ability to accommodate a high degree of anion vacancies‚ crystal structure and its high Neel Temperature (TN). It also exhibits polymorphism with two different cubic and hexagonal structures

REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where oxygen is added

Imagine having nonstop growing fat on your stomach. That is what happens with Gaucher’s Disease. Gaucher’s is when your recessive gene gets duplicated and the metabolism gets built up with fat called glucocerebroside and it can’t be degraded‚ you can’t get rid of it. Some of the major causes are enlargement of the stomach or spleen. You can also have a low amount of red blood cells. Some symptoms of this disorder are easy bleeding or bruising‚ extra fat on stomach‚ bone and joint pain‚ and weak bones
