Calcium carbonate

The creature that is being examined in this experiment is the now extinct Spinosaurus aegyptiacus, a dinosaur that lived in Northwestern Africa about 95 million years ago. The Spinosaurus (fig.1) was a creature that has been estimated to be anywhere from 13 to 18 meters (43 to 60) long, weighed 7 to 9 tonnes (8-10 tons), and is agreed to be by most paleontologists the largest carnivorous dinosaur of all time. It is thought to be a piscivore, although the Spinosaurus’ diet and lifestyle is very…

lowered the pH levels in the oceans by .11 which has caused the ocean to be thirty percent more acidic than it was in 1751. The acidification does not affect just the coral reefs, it also affects snails, urchins, and clams because they use the calcium carbonate to make their shells. If the world continues on the path it is going on today, the pH levels will lower by 7.8 by the year 2100 which may seem far away, but it is closer than you might think. If the levels lower to that amount, the…

He was fascinated by human form and that reflected in his artwork. The sculpture looks so realistic and contains a lot of details. The materials that he used to make his sculptures are silicon, resin, calcium carbonate, and human or animals hair. Sam’s work is realism and it comes from his experience and most of these experiences are connected to the moment they happened. Jims said, “I just create things based on the way I feel at a time, and while it may mean…

PHYSIOLOGICAL DIMENSION IMMUNE/DEFENSE MECHANISMS Age specific variations of growth and development From the Nursing care of infants and Children, specifies different immunizations that are recommended for adolescents. Adolescents that are 11 to 18 years of age should be administered the tetanus, diphtheria, acellular, and pertussis vaccine. The meningococcal vaccine should be administered to adolescents between the ages of 11 to 12 years old, as well get a booster before the age of 16.…

Coffee plants require constant application of nutrition for better yield and quality beans. Sixteen elements with are essential for the development and growth of a healthy coffee plant. These are categorized into two, macronutrients and micronutrients. Macro nutrients are further categorized as Primary and Secondary nutrients. Nitrogen, Phosphorus and Potassium constitute the primary nutrients as large amounts are required by the coffee plant. The development and growth of the plants depends on…

showed the temperature was rising too high for the coral to grow, but it was not high enough for the reef to bleach. In addition to bleaching, another major aspect of reefs is the calcification. It is important as corals are built from layers of calcium, but the temperatures could play a key role here. However, there are contrasting results as data from one area of the Great Barrier Reef shows an increase in growth when temperatures rose one degree Celsius, but in another area the growth decline…

A female Mini Schnauzer named Maggie and found that after a while of having her, she started chewing on her back & legs with some spots on her looking pretty raw. We examined her and knew she didn't have fleas and we started to worry that her hair wouldn't grow back in the raw areas. We decided to take her to the vet to see what was wrong. The vet had the usual answer of the dog has allergies and could either give her shots (expensive) or try a cream/lotion. We decided to go to the pet store…

Discussion of Results: This experiment consists of three different parts. The main goal of the experiment is to identify the unknown compound the lab group was given. Along with this, the group is to discover the compounds many physical or chemical properties. Lastly, the group is supposed to create and preform two syntheses of the compound and see how they compare and contrast in different areas like costs effectiveness, safety, and potential yield of the compound. Through all of these…

Abbylyn Sessions Professor Livingston Geology 1100 28 August 2016 Fantasy Field Trip Just outside of Custer, South Dakota is a hidden geological treasure: Jewel Cave. Jewel Cave has over 181.89 miles in mapped passageways making it the third longest cave in the world (United States. National Park Service). The formation is lined with calcite crystals creating a beautiful view inside. Jewel cave is a geologic wonder that would make a great field trip. A field trip to Jewel cave would allow the…

stereocilia, on top of the hairs we have a liquid called cupola. When the cupola moves across the stereocilia it sends a stimulus down the vestibulocochlear nerve, giving the brain a sense of balance. Occasionally, after brain trauma, a small calcium carbonate…
