Daphna Magna Experiment

The experiment focused on the fact that certain organisms are affected by light and will move depending on whether or not light is present. There were four organisms that were placed in a tray that was half lit and half dark. Euglena is a photosynthetic organism that uses light as a vital part of its existence. Euglena showed a significant preference for the light side over the dark side (X2 = 529, p<0.01) (Table 5). Phototaxis is an organism’s movement as a result of light (Urry et al. 2014). If an organism is attracted to light it is an example of positive phototaxis

Boats are very common on the lake, both for fishing and recreation. The lake is a popular to anglers looking for kokanee salmon (Oncorhynchus nerka) and lake trout (Salvelinus namaycush). Other fish like rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) are also abundant in the lake. Mysis shrimp were introduced into the lake many years ago. They have had an impact on the kokanee salmon and will be analyzed in the final paper. The fishing industry provides income for the area, as well as jobs. As of recent, the populations of kokanee salmon and lake trout have been in a decline. The interaction of human management on these fish populations is needed in order to help increase these fish abundance in the lake. This issue is also linked to the management of water in the lake because water levels impact the way that fish species

The purpose this issue became of great significance these years is that the water pollution can not only poison the creatures in the water. Also affect the quality of Biodiversity declines

With all if the pollution, fish die. The pollution can cause no oxygen in the deeper part of the lake for animals. Studies show that in the late summers, parts of the lake do not have oxygen for animals in the deeper parts. From that, animals

Detail 1: When animals such as otters clean themselves after swimming around in oil, they will ingest some oil. After they eat the oil, they will be poisoned, which will kill

The purpose of this experiment is to see how roundup effects invertebrate’s species like daphnia, and the measurement of the aquatic toxicity test. My hypothesis for this lab is that the mortality percentage of Daphnia will rise as the concertation of the tested product roundup increases, in one of the concertation’s I didn’t think any of the daphnia will survive.

In the article, On the Limitation of the Term ‘Petroleum Products’ in the Determination of the Oil Pollution of Bottom Sediments (2017), Z.A Temerdashev (also this article’s corresponding author), L.F. Pavlenko, I.G. Korpakova, and G.V. Skrypnik et al. investigate the overuse of the term ‘petroleum products’ upon measuring levels of exposure to toxins, carcinogens, and mutagens in bottom sediments of the Sea of Azov & the Black Sea, as well as identify a more effective way of studying this concept. Through the process of bioaccumulation, toxic bottom sediments disrupt the food chain of organisms living the the ocean. Although scientists, along with much of the world’s environmentalists, have already gained knowledge of the potential risks

This paper is about the effects of offshore drilling particularly it discusses “oil spills caused by offshore drilling in California”. These oil spills that are caused by offshore drilling affect the environment in the long run. Even some of these impacts on the environment by oil spills last for decades (Larry West). For example when an oil slick arrives at the beach from a huge oil spill then it sticks to each grain of the sand and every rock. So if this oil is absorbed by the forests or fibrous plants etc. then it can make the whole area unsuitable for wildlife. Moreover if this oil spills stops and sinks in the surface of the water then these oil spills damage the fragile ecosystems under water and can prove extremely dangerous to marine life (Jennifer Horton).

The introducing to any type of pollution, man-made or artificial, can have an outstanding effect to a natural environment. When the word of pollution is thought of, it’s never a positive thought and can do harm to where humans and many different organism lives. There are many different freshwater pollution and each one of having it one effect. One of the organism that live is fresh water is Ankistodemus, a green alga that grows in fresh water pond and lakes. When Sodium chloride (salt) is added to the alga environment what type of effect will it have on its growth? The importance of this experiment to make aware of how pollution have a stern effect on the living things around the Earth. Being alert of this will expression how putting more care on the environment will extend the life span of the Earth. The goal of adding Sodium chloride, the pollutant, to water, that Ankistodemus live in, is for illustration how Sodium chloride will inhibit the growth of Ankistrodesmus algae.

The first solution, bioremediation, is the most prominent and promising new innovation accessible to clean the oil spills, which possibly could uproot the oil in an innocuous way, from even the most obstinate and untidy situations, where it has sunk into shorelines and mangrove bogs, and even in submerged oil crest. Some naturally occurring microbes that process crude oil are known to exist in the ocean (“PROOYEN”). Be that as it may, the measure of oil spouting into the sea as a consequence of the BP oil spill is much

Oil spills are large pools of oil spread across a large area on top of the surface of an ocean but can also lead to multiple harmful effects to an ecosystem to marine animals present in the area .Multiple variables can lead to an oil spill, some oil spills can happen by outdated equipment or poor weather conditions while others can be caused by mistakes or ignorance of the workers like with the Exxon Valdez in March 1984 .Oil spills that occur near shore can be hazardous areas for aquatic and marine animals present in the area,When oil is ingested by marine animals it can have long term effects on the animal's health and can temporarily cause the inability for the animal to float above water and to keep warm which is vital for these animals

The aim of this experiment was to test whether the bunker fuel oil affects the acidity of the water from various locations. The hypothesis is ‘If the amount of exposure to pollution is increased, then the pH of the

Marine oil spills have short and long term effects on marine life and habitats. The short term effects are well known and predictable so they can be dealt with. Long term effects are known as ‘sub-lethal.’ A short term effect is something that can be dealt with in a short period of time. In terms of sandy shorelines, this includes using modern and natural cleaning methods to clean the oily contamination from the sand. Long term affects, on the other hand, are the opposite and include the left over oil that might be too deep in the sediment. This oil can be ingested or absorbed in some way by organisms such as crabs and reptiles.

These effects are particular with the environment and a number of pollutions are present including air, water, industrial, carbon, and marine pollutions. All these pollutions have a varying degree of effects in their particular environments. The essay is focused to investigate causes of marine pollution and its effects on the sea life. The solutions are also provided to mitigate the effects of marine pollution.
