We were gonna do another experiment, the Acidity Test but we didn't get to. We do have the results from the Acidity test from another time. We found many different critters in our group. Some of them were big and small and they were all different.
All organisms need oxygen to survive and when their is not enough oxygen, it leaves plants and animals to die. The area of water where there is a low count of oxygen are often called a dead zones. Also, an increase of the pH level in the water can be created because of algae blooms. The toxic killing algae can make humans sick. For the aquatic animals, these toxins attack mainly the organisms liver and nervous system (Nitrogen and
The four-days of World War II it was skirmisk in May 1942 they marked the first air-sea battle. Then the Japanese was seeking to control the Coral Sea with an invasion Port Moresby in southeast of New Guinea, but they made plans to intercepted by Allied forces. The first-air battle they had engagement in which the lead role was played by aircrafts launched from ships at sea. Then the war was resulted from the Japanese. The unknown to the japaneses, the Allied of codebreakers had learned enough about the enemy’s.
The crown of thorn starfish, Acanthaster planci, are currently responsible for a majority of the coral reef destruction occurring throughout the world. This creature consists of 13-16 arms that allow it to easily latch itself onto its prey. Crown of thorns starfish also contain a venomous spikey exterior that help protect them from predators that may be searching for an easy prey during their four to six-hour feed. These starfish consume coral by extruding its stomach and secretes emulsifying enzymes the will aid in digesting of the coral polyps and nutrients. After this process has concluded the left-over coral will turn paper white which signifies its death.
The purpose of the experiment was to determine what happened during osmosis and diffusion across membranes by using a fresh hen’s egg. During the first step, the egg was put into the vinegar. The shell of the egg became soft and started to fall off by small pieces. The reason of the vinegar was able to remove the calcium shell was that the acetic acid in the vinegar could react and dissolve the calcium. The formula for this reaction was CaCO3 + CH3COOH –> Ca + H2O + CO2.
Ocean acidification, as its name suggests, is the decrease in PH value of the seawater. It is caused primarily by the uptake of carbon dioxide in the atmosphere. Oceans were known to balance the components of atmospheric carbon dioxide and mitigate climate change. However, the current rate of intake of carbon dioxide is about 100 times faster than ever before (Oceana, 2012). The rate of absorption is so fast that it alters the chemistry of seawater.
One fundamental characteristic of red coral that distinguishes it from other ‘gems’, is its naturally branching dendritic form. The analogies made between branching coral and trees, was a longstanding one. According to historian, CAS Williams, red coral ‘was anciently supposed to represent a tree called the T’ieh shu [tieshu], which grows at the bottom of the sea, and flowers only once a century’. This suggests a link with marine origins, as well as rarity and a supernatural nature.
An increase in seawater can thus reduce the effects of the sunlight on the coral, which can cause the death to only be
How are coral reefs formed? Coral reefs are formed by floating coral larvae that attach to rocks that have already been placed in the ocean or any other hard surface. These then grow along the edges of islands or continents. There three different types of reefs.
CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq)
Ever since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change. The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out
The acidity can cause them to absorb larger amounts of aluminum, and this combination “makes waters toxic to crayfish, clams, fish, and other aquatic animals” (National Geographic., n.d.). This has a negative impact on the food chain, as all ecosystems are
Thus, it can cause death of the aquatic animal and increase in sea acidification as increase in the concentration of carbon dioxide. Besides, the studies shown that more acidic environment have dramatic effects on some calcifying species such as oysters, sea urchins, deep sea corals and others. Due to this environment, the shelled organism will expose to the risk and pollutant which can give negative impact to the human health who consume as food as sources of protein. When water (H2O) and carbon dioxide (CO2) mixed together, they will combine to form carbonic acid which is weak compared to hydrochloric acid.
It is important that coral reefs recover once they have been damaged, some of the consequences are; less diverse reef communities, decline in fisheries, tourism and coastal protection (Hoegh-Guldberg et al, 2007). There are 5 potential predictors for how well a coral reef will recover after bleaching (Graham, Nash & Kool, 2011). Firstly, the reef characteristic, if the skeleton of the reef is still present it is likely to maintain ecological processes and therefore recover rapidly (Graham, Nash & Kool, 2011). Secondly, the connectivity of the reef, high connectivity of coral reefs is important for recovery, isolated reefs are more likely to have a slow recovery (Graham, Nash & Kool, 2011). Thirdly, the ecological characteristics of the reef,
The strongest effects are caused by suspension of silt, sedimentation, turbidity, oxygen reduction and the release of bacteria and toxic matter. A massive quantity of either coarse or fine particles will bury the corals, which are unable to withstand cover for more than one or two
