Mercury's surface is similar in appearance to the appearance of the Moon, showing plains and heavy cratering, indicating that it has been inactive for billions of years. Knowledge of Mercury's geology has been based only on the 1975 Mariner flyby and terrestrial observations, it is the least understood of the terrestrial planets. As data from messenger orbiter is processed, this knowledge will increase. For example, an unusual crater with radiating troughs has been discovered that scientists…

Equilibrium Paper There are multiple ingredients used to make baked goods rise; baking powder and baking soda are among them. The difference between single and double-acting baking powders is simple. Single-acting releases the carbon dioxide bubbles when mixed with a liquid ingredient and double-acting soda releases bubbles when the baked item is placed in heat. Baking soda and baking powder are remarkably similar, yet there are distinct differences. One is that baking soda is a strong base,…

energy is converted to chemical energy. Chlorophyll and other pigments absorb energy from sunlight. This energy is transferred to the photosystems responsible for photosynthesis. Water is used to provide electrons and hydrogen ions but also produces oxygen. The electrons and hydrogen ions are used to create ATP and NADPH. ATP is an energy storage molecule. NADPH is an electron carrier/donor molecule. Both ATP and NADPH will be used in the next stage of photosynthesis. The light independent is…

as a catalyst by absorbing oxygen, which kills bacteria by interfering with their respiration. Because of this antibiotic property silver had an essential role in medicine for thousands of years. Before the use of antibiotics, silver foil was wrapped around wounds to help healing, and silver-protein complexes were ingested to fight illness. Silver has also been used in dental hygiene to cure and prevent infection.…

Amnion Tissue In this project, I also with amnion tissue collection, ChIP preparation and Real-time PCR technique. The aim of this work was to determine the gene activating H3K4me3 and gene repressing H3K27me3 levels and their ratios at the promoter regions of NAMPT inflammatory gene. Collection of Tissue Fetal membranes were collected from women undergoing elective cesarean section at absence of labour [not in labour (NIL), n = 5], during active labour [in labour (IL), n = 4] and preterm (n=5)…

A) The Earth’s early atmosphere had no oxygen and was made mostly of nitrogen, with some carbon dioxide, water vapour and hydrogen compounds such as methane and ammonia. Within million of years life evolved in the oceans. 3.2 billion years ago photosynthesis had evolved with the first oxygen producing cyanobacteria, similar to today’s blue-green algae. At first, the oxygen given off simply reacted with the rocks, but gradually it built up in the oceans and started to bubble out into the…

A recent study on Mars’s geology causes a paradigm shift to researchers’ perspective of the red planet. Felsic rocks that thought to not exist on Mars are now identified. Overall, these findings alter the understanding of the geologic complexity and magmatic activity of Mars. Prior knowledge of Mars’s geology was rather simple; consisting of one type of rock formation in contrast to Earth’s diverse and complex geology. Felsic rocks such as granite, are common in subduction zones on Earth (Wray…

The element Magnesium got its name when it was discovered. It is a silvery white metal that is highly reactive. Its chemical symbol is Mg and atomic number is 12. Its atomic mass is relatively 24. Therefore, it has 12 protons, 12 neutrons, and 12 electrons. According to Steve Gagnon in “The Element Magnesium” Magnesium was isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide and mercuric oxide in 1808. Magnesium has a melting point of 650°…

Dalton’s Law Challenge Question: Ordinary air contains about 78% nitrogen, 21% oxygen, and small amounts of several other gases. As a diver descends, the pressure of the air he is breathing increases by about one atm for every 10 m of depth. Oxygen may become toxic and cause convulsions if it is breathed at a pressure above 1.4 atmospheres. According to Dalton’s Law, at what depth should a SCUBA diver be concerned about oxygen toxicity if he is breathing ordinary air? Discussion Points: •…

carbon dioxide which is quite acidic, the more carbon dioxide in the breath the more will be going into the water causing it to change colour faster. Carbon dioxide is a byproduct created during the production of energy. how energy is made is by using oxygen, inhaled from the air by breathing, and glucose which is a basic sugar from eating food, all through the bloodstream. By breaking the chemical bonds and rearranging them we can create different chemicals, in this case; water, Carbon dioxide…
