The Rock Cycle & Classification of Rocks The rock cycle is the formation‚ breakdown and reformation of a rock as a result of sedimentary‚ igneous‚ and metamorphic processes. The rock cycle is an illustration that is used to describe how the three rock types are related and how Earth processes change a rock from one type to another over time. Each group contains a collection of rock types that differ from each other on the basis of the size‚ shape and arrangement of mineral grains. Due to the driving

Several things occur in the Krebs cycle. It takes place in the mitochondrial matrix. The electron transport chain is located in the cristae of a mitochondria. The enzymes used during the Krebs cycle are found within the mitochondrial matrix excluding succinate dehydrogenase‚ which is bound to the inner mitochondrial membrane. Protein complexes located in the inner membrane perform the transfer and the gradual release of energy is used to pump protons into the intermembrane space of the mitochondria

The Carbon Cycle Poppy Matless Carbon is present in all living organisms. When organisms die‚ the carbon is recycled for future generations. 1. Carbon is released as CO2 via respiration and combustion 2. CO2 is absorbed by producers (grass‚ plants etc) 3. Animals feed off of the plant‚ passing on carbon throughout the food chain‚ losing some carbon as CO2 respiration. 4. When the animal dies‚ it is eaten by decomposers‚ and the carbon returns to the atmosphere 5. If decomposition

Yellow Stone National Park Alejandro Otero SCI/256- People‚ Science and the Environment Ms. Nathalie Basma July 30‚ 2013 Yellow Stone National Park “The human history of the Yellowstone region goes back more than 11‚000 years. From then until to the very recent past‚ many groups of Native Americans used the park as their homes‚ hunting grounds‚ and transportation routes. These traditional uses of Yellowstone lands continued until a little over 200 years ago when the first people of European

CYCLES IN BIOLOGY This essay will give examples of cycles in biology from different scales of magnification‚ ranging from molecular level to populations and ecosystems. Cycles are sequences of events which repeat themselves in the same order‚ one event leading to the next. There are many examples of these in Biology. Cycles can be seen even at a molecular level in the body. An example of this would include the passage of action potentials down neurones in the nervous system. When the cell membrane

The Calvin Cycle By: MJ Pineda The Calvin Cycle is basically a part of photosynthesis where plants take in carbon dioxide and uses ATP and NADPH to make sugars from the CO2 and water for the plant to use or for animals to eat. It does not require light‚ and is interestingly called the "dark cycle" 1. The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. 2. The six carbon molecule that

The Calvin Cycle Plants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process of photosynthesis‚ they convert the sun’s energy into storable form in ordered sugar molecules such as glucose. In this way‚ carbon dioxide from the air and water from the soil in a more disordered state are combined to form the more ordered sugar molecules. Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after its

The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available
