that zebra mussel has long been spreading out from its original habitats and has now reached parts of North America. therefore it poses a serious threat to freshwater fish populations in all North America and provides three reasons for support. However, the professor explains that zebra mussel is not likely to the serious threat to the freshwater fish population and refutes each of the author's reasons. First, the article claims that it is possible that zebra mussel spread to North…

change that led to glacial like weather occured. This period is known as Younger Dryas Climate Event. Due to the earth warming, the ice age starting melting. This huge amount of freshwater started flowing into the gulf through the Mississippi River and also to north Atlantic from the east coast. This unusual flow of freshwater into the saltwater caused the water currents to change suddenly causing different weather patterns. The earth started experiencing freezing temperature that were…

1. The Karo syrup experiment started with our dialysis tubing bag with Karo syrup in the bag and the initial weight was 11.09 ounces. We left in a beaker of tap water for 45 minutes and the final weight was 17.98 ounces. The dialysis had a semipermeable membrane and the water soaked through the bag of the syrup. This created a solution of water and syrup 2. The plant takes up water by osmosis and starts to swell. The cell wall prevents it from bursting. Animal cells don’t have a cell wall so…

in fresh water sources. According to a study done on “Approximately 100 new species of freshwater fishes are described each year, compared with perhaps 2 new bird species” (Allan and Flecker 1993). Among the new species are species that are endangered or unique only to those fresh water sources. “‘A substantial fraction of the rare and threatened species of North America are aquatic, and primarily freshwater taxa”’ (Allan and Flecker 1993). Biodiversity is incredibly important to maintain…

uncertain [Ciais et al., 2013]. One of the largest unknowns is the accuracy and precision of freshwater partial pressure of CO2 (pCO2) estimates. To better understand observational uncertainty in CO2 flux from inland waters, here we conduct an analysis of historical observations and take new field observations at the North Temperate Lake Long Term Ecological Research (NTL LTER) site to quantify random errors in freshwater carbon system. We further estimate errors contribution to the precision of…

can relieve work stress and even anxieties. Of course, who can resist from its flashy color, flaunting tails and alluring appeal? Betta fish is a tropical fish originally came from Asia. They come in different varieties and breed. Since they are freshwater fish, they are more likely to be placed in a small fish bowls or in a larger aquarium. They look lovelier when placed near the entrance door. But what are the things to consider when caring for this fish, aside from its aquarium? Here are the…

Article 1: According to Karl Hanes in his “Effects on Salinity in Florida’s Estuaries”, Florida’s most important estuary, economically wise, will be impacted on greatly as a result of climate change. This climate change is causing the sea-levels to rise and a change in the river flow to occur. Due to this, an increase in salinity levels will result in the harming of the biodiversity and their habitats that are present within the estuary. As a result of high salinity levels many of the estuaries…

Fund, 1.1 billion people worldwide do not have freshwater at hand, and 2.7 billion face insufficient freshwater for over a month each year. It is crucial for society to be aware of this issue because water is being managed poorly. The British Broadcasting Corporation states that within the past 40 years, global water consumption has quadrupled, despite the population doubling. If this is not adverse to…

pond at your local park. These sources like the pond are considered freshwater ecosystem. Water is a neutral compound, meaning that in its natural state, it is neither acidic nor basic and has a pH of 7. However, water is subject to pollution and can easily be polluted by acidic compounds. And when you live in an area with a refinery, the surrounding waters can be very polluted. For this lab, we will test the various freshwater sources around Madison County and determine whether they are…

the effects of global warming on the polar regions are likely to have major repercussions in the rest of the world. How does pollution in the polar regions affect biodiversity There are at least four types of pressure acting on marine, coastal, freshwater, and terrestrial habitats that affect both their conservation and biodiversity: issues relating to the exploitation of species, especially…
