The variables measured are nitrate, nitrite, total phosphorus, ammonia and transparency. Harrison also states that river and Lake Eutrophication is a problem across most of Europe because of excessive nitrogen and phosphorus levels from agricultural, industrial and domestic effluents. Harrison states that natural organic matter is present in most natural eco systems.
Present and diverse macroinvertebrates signify excellent ecological quality. The organisms live and feed on leaves that accumulated on the bottom of streams, so the tests were done by scooping up leaves in the lakebed. There were approximately eight to eleven macroinvertebrates found on in the bottom of the lake. The results were fair, but not as positive compared to the sixteen and above macroinvertebrates found by the dam. Based on the results, one can predict that the ecological quality of the dam is increasingly better than the quality of the water on the hill.
The amoeba is scientifically known as the Amoebidae. It is mostly a freshwater organism. It is commonly found in ponds, rivers, lakes, and one in a while the ocean or bay. They are typically on leaves of plants so it can find food but you may find it floating to. Amoebas are also rarely found in the soil and sometimes they do go inside a animal body like a parasite.
Alkalosis & Acidosis Shalita Johnson SC131 Respiratory Acidosis: This is a condition that occurs when the lungs cannot remove enough carbon dioxide that is produce by the body. When the body have excess carbon dioxide (CO2) this causes the pH of the blood and other body fluids to decrease, this make them acidic. This can be known as ventilatory and respiratory failure. Normal range: PaCO2 35-45 mmHg. pH levels are 7.35 to 7.45.
The adaptive features of animals: i. Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.
Most of the time, these winds drive a lot of food sources in the water so that the crappies will feed there. To conclude, the best spawn area is one which shallow and has the windward shore. Keep in mind that it is not the spot where you will catch the prey. It is only the initiation of your fishing location. Based on crappie spawning nature, they will use the passage (drop offs) to find natural covers such as brush piles, stumps, deep channels, etc.
Daphnia are very abundant organisms in freshwater lakes. They tend to live in the upper algae rich portion of the water, feeding on phytoplankton, bacteria and decaying organic matter. Daphnia and bosmina both serve an essential role in he food chain in most lakes, serving as a resource for numerous predators. Trout tend to feed on small crustaceans like daphnia and dosmina. Trout are visual predators and therefore feed on the larger daphnia thus providing bosmina a competitive
Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap
The cuttlefish is an amazing marine animal, one of the most intelligent invertebrates. It is not actually a fish though, it is in the category sepiida. There are over 130 different species of cuttlefish. This mollusc has a very large brain and a very unique eye. It has 8 arms and 2 tentacles that have suckers on them so they can grab their prey.
