The Effect of pH levels on the Motility of Daphnia in Lake Ecosystems Introduction: The production, transportation, and use of chemicals by chemical industries can result in chemical pollution. This leads to a harmful effect on ecosystems and their balance of life (Linlin, Chen, 2012). The pH levels of aquatic environments are important because it affects the physiology of animals by changing their behaviors. The ion concentrations associated with the water and the organism’s survival can also…

within 1 [metre] of mean sea level”, meaning that close to 100 million people could and will be displaced from their homes within the next few hundred years, due to sea level rise (2010). There are several factors that contribute to the rise of global sea-level, both directly (warming oceans, expansion of ocean particles and melting glaciers) and indirectly (global warming and the loss of ice shelves). While ice shelves don’t directly contribute to the rising of sea-level, they play an important…

There are two major trophic cascades that scientist use. One is called bottom-up and the other is top-down. The controller of top-down would be the top predator or the apex predator (Wallach and O’Neill, 2009). The apex predator can also be known as the keystone species in that ecosystem. Top-down control is when the apex predator regulates the structure and population of the ecosystem (Wallach and O’Neill, 2009). The apex predators will prey on the consumers, which keeps the consumers…

honors.” This level of measurement is impartial and should not be used in calculations, but we continue to use this type of data to classify students inadequately. The interval level of measurement provides more concrete data analysis. Values are created based on data that can be ordered and have a distinct difference between each level, hence the term interval measurement. Variables at the interval level can be used in calculations and drawing conclusions. The interval level does not have a…

Living as Night and Day: the Story of Two Brothers. Between my brother Joe and I, you could not find another pair so unalike. Despite growing up in the same household, ate at the same table, we experienced different things. After our experiences, Joseph became an exceedingly negative man. The man ignorant to others feelings; careless to everyone else’s convenience. Impatience, arrogant, chauvinistic and shrewd. I am the opposite of my brother, which makes me proud. Unlike Joesph, I’ve learned…

up, polar ice caps begin to melt. The icecaps release furthermore methane gases into the atmosphere and continue to heat the globe. The melting of the icecaps also results in higher sea levels which in turn harm coral reefs and decrease the land of those who live near costal regions. According to the NRDC, “Sea-level rise can lead to saltwater intrusion into groundwater drinking supplies”. The increase of heat causes snow to melt and animals such as the arctic hare become extinct because they…

interval levels of measurement. The reason they are interval levels of measurement is because the test results are ranked, mutually exclusive, and there is meaning between one category value and another (Kim & Mallory, 2014). Other examples provided by Kim and Mallory (2014) of interval levels of measurement included scored tests and questionnaires, which is the nature of both the PACER test and ASSQ survey. The dependent variable of adiposity reduction is the continuous variable, ratio level of…

The levels are made up of the tertiary consumers (carnivores), secondary consumers (small carnivores and herbivores), primary consumers (herbivores), and producers and decomposers (plants and insects). The stronger and more dominant animals in the jungle are…

booming city with a whopping 37,000 residents living there. Reaching a maximum elevation of 8.7 feet, most of Galveston was even to sea level or right above it. Even with being such a small land mass, Galveston was well on its way to becoming one of the most important ports in the United States.…
