My hypothesis, if we test the water from the Conodoguinet Creek for signs of pollution, then the results would be negative for the pollution because the water appears clear at most parts of the river, is somewhat correct. Based on our findings, the degrees of pollution of the Conodoguinet Creek are very low. The phosphate levels, phosphate meaning a salt or ester of phosphoric acid (mineral acid), are at most 1. Nitrate is a salt or ester of nitric acid. The levels of nitrate are also very low,…

asic Morphology “oriental lung fluke” = common name Infections may persist for 20 years in humans. (CDC) Animals such as pigs, dogs, and a variety of feline species can also harbor P. westermani. (CDC) Human infection with P. westermani occurs by eating inadequately cooked or pickled crab or crayfish that harbor metacercariae of the parasite (CDC) Penetrate through the intestinal wall to peritoneal cavity, then through the abdominal wall and diaphragm into the lungs, where they become…

mouths. Their throats then contract to filter the water out, thereby retaining thousands of tiny creatures due to the baleen plates, which they then swallow. Thanks to their 3-chambered stomach, they are capable of digesting the hard exoskeleton of crustaceans. Blue whales are able to consume up to six tons of prey every day during the summer. The mouth contains 270 to 395 hard, bristle-like baleen plates that hang from each side of the upper jaw, which are used to filter food out of the water,…

other fish and animals. The fish of omnivorous category feeds at the ocean’s bottom contains a mixed diet. They’re naturally opportunistic and survive on nearly any sort of food they get near the sea’s bottom. Their diet consists of small fish, crustaceans, worms, and almost anything that is not poisonous. Fish live in nearly every large body of water in the world including streams, rivers, ponds, lakes, and oceans. Some fish live on the surface of the water and some live in the very depths of…

food is lobster and drawn butter. Author Elizabeth Townsend (2011) informs: The world’s love affair with lobster began out of necessity. It wasn’t a mutual affection though: it was as lopsided as unrequited love. Humans needed to eat and the crustacean was often within easy reach by hand, spear, long hook, baskets and later nets and traps. But the shellfish eventually became more than just grub – its status shifted from vital protein to pauper’s food to cultural icon (p.…

• Blue-ringed octopuses usually appear as pale-brown in colour and can only be identified from different octopi from the bright blue rings. • The size of the octopus is around 15 cm at a maximum. • The blue ringed octopus is found in subtropical waters off eastern coast of Australia, south of the Great Barrier Reef around Bundy and back down towards New South Wales area. • The blue ringed octopus has a small beak which is located on the underside of the head that contains the poison in the…

Invasive Species are plants, animals, or pathogens that are non-native (or alien) to the ecosystem and whose introduction causes or is likely to cause harm. Some of the characteristics are to tolerate a variety of habitat conditions, they grow and reproduce rapidly, and they lack natural enemies or pests in the new ecosystem. Some of the environmental impacts of invasive species are the extinction of local species, irreparable changes to the habitat, biodiversity of invaded ecosystems, and…

Daphnias affected Heart Rate This lab experiment was conducted on Daphnias to test the chemical effects on its heart rate. In this experiment we determined the effects of caffeine and alcohol on the small organism. If the Daphnia is submerged in alcohol the heart rate will slow down, as if it’s submerged in caffeine it will speed up. The experiment measured how the stimulant caffeine or alcohol affected the Daphnia. The objective was to see how alcohol and caffeine would affect the…

WHERE DOES BLACKTIP REEF SHARK LIVE? Blacktip reef shark (Carcharhinus melanopterus) DESCRIPTION The blacktip reef shark not the same as blacktip shark (Carcharhinus limbatus), though they possess similar attributes but also different species of shark. The blacktip reef shark is famous for the black tips on its fin which also makes it to be easily identified, also known as black wing shark. As its name says, blacktip reef shark's pectoral fin tip and dorsal fin are black, while the lower part…

of whale evolution, Odontocetes and Mysticetes, both Cetaceans. Odontocetes, the Toothed Whales, and Mysticetes, Baleen Whales (“Into”). Mysticetes use a straining system when they eat; Mysticetes can eat large quantities of fish, plankton, and crustaceans in one swallow. Some examples include: Fin Whale, Bryde's Whale, and Humpback Whale (Kennedy). Odontocetes contain 72 different types of toothed whales. Examples of Odontocetes include: Dwarf Sperm Whale, Burmeister‘s porpoise, and Sperm Whale…
