Neeritic Zone Essay

The Fertile Crescent stretches like a crescent moon from the eastern shore of the Mediterranean Sea to the Persian Gulf, containing Egypt and Mesopotamia. The terms mentioned throughout the essay are different empires and locations. Sumer was the first civilization and is located in the narrowing plain between the lower reaches of the Tigris and Euphrates rivers. About 5,000 years ago, Sumerians developed writing, construction of cities, and domestication of animals. The Akkadians took over Sumer around 2350 BCE when Sargon I. became leader and began seizing territories as reward for winning a war. Ancient egypt, laid southwest of the Fertile Crescent alongside the Nile River in Africa. People have lived there since around 5000 BCE and began

The Ocean has many ecosystems and animals that live and survive in there. We depend on some of the natural resources the ocean provides. We are hurting this by dangerous fishing and overfishing or overexploitation of the fish. The ocean has a great diversity

fish. The structure of each different type of tail is radically different. Some lizards have

The way it gets its prey is by using its long tongue. This tongue has a sticky spot on the tip just like frogs. It can use this tongue for like a grip. If it happens not to use its tongue, it can use its powerful jaw.

3) Which of the following is considered to be an original hearth of urban settlement?

Kelp forests are seen as the ultimate ecological engineer in coastal areas. They exist in marine environments spanning in southern California, Aleutian Islands, and the western north Atlantic. Light, latitude, and water temperature and nutrients all play a role in facilitating the growth of kelp forests all around the world, (Bolton). Kelp specifically dominates the shallow rocky coasts of the world‘s cold water marine habitats. Although they look as a free-growing plant, they are in fact primarily of brown algae. These structures provide food and shelter to a huge mix of biota, including crabs, sea urchins, mollusks, and other marine organisms (Steneck). The fronds, or large leaves of the kelp are the distinctive feature that can represent where a specific kelp may be found. The sizes of these organisms can range from the smallest found near California and Alaska at 5m to giant kelp up to 45m in length found on the west coasts of North and South America (Hamilton).

Imagine that a huge wave crashes down on you. Then it drags you back into the ocean. On your way you pass by an animal that is clinging on for dear life. In order to survive in these harsh conditions, animals need adaptations. An ecosystem is a biological community of interacting organisms and their physical environment. The California Spiny Lobster lives in the neritic e zone which is in between 200 meters and 0 meters. It is located on the continental shelf. They like living in coral reefs and the ocean ground. In order to survive in the neritic zone with predators, sea floor hiders, and other environmental threats, animals need adaptations.

jaw structure. The teeth are actually modified, enlarged placoid scales. The teeth aren’t anchored in the jaw; they are just embedded on the gums. Unfortunately, when the great white shark eats on its prey, it sometimes loses or breaks the tooth by the flesh. Luckily, sharks have developed a special feature that enables it to replace its missing tooth. They have developed rows of teeth, each tooth moving up to replace the missing one. A whole broken row of teeth can be replenished, just like a conveyor belt. Each tooth, though, has a different shape, changing according to its necessity. The great white has triangular, serrated-edged teeth anywhere from one to two inches long. With this feature, the shark is able to tear through the flesh for its meal. The jaw of the shark is made up of strong bone tissue. It must be very powerful because the shark is designed for feeding.

II. the second reason is because the whales do a lot of turning since they cannot swim in a straight line as they do in the wild, thus bending the fin.

Some species might thrive in conditions that other struggle to survive. For example some predators might need more oxygen then a smaller prey. With less predators being around, there is a huge burst in prey, which can eat up all of the bacteria. When the bacteria all die, the prey can’t find any food and all die out. This causes a very unreliable food chain and can be dangerous to live in. In hypoxic zones what tends to happen is that marine life such as fish or shrimp die out quickly while the smaller organisms live. This causes whole species to die out leaving a dominance of gelatinous creatures such as jellyfish to thrive in.

As mentioned earlier, the Neandertals possessed large, stocky physiques that were built to withstand the frosty weather. This is an example of a biological adaptation in response to their terrain. Without their large builds, the Neandertals would not stand a chance in the wintry weather. Along with their biological adaptation, Neandertals adopted behavioral changes as well. They even began clothing themselves. It is said, Neandertals used animal skins and hides to protect themselves from the cold (Stanton, et al., 2013, p. 405). While they clothed themselves, it was not fully effective protection against hypothermia. Hypothermia is a probable explanation to the extinction of the Neandertals; however, the Neandertals avoided the climate by seasonally migrating over long distances or by moving as overall conditions get colder (or warmer) during all parts of the year (Stanton, et al., 2013, p. 406). With their migration system, they were out in the open and inadequate portable insulation had additional ramifications for Neandertal survival (Gilligan, 2007, p. 507). The Neandertals lived nomadic lifestyles and that contributed to compromises in their hunting and gather activities as well as their fertility rates (Gilligan, 2007, p. 507). There was an evident rise in their adult mortality rates alongside with their even higher infant mortality, in view of the fact that they render infants more prone to hypothermia as

Hammerhead skin is covered in closely spaced denticles that are overlapped on front and two lateral sides. They are diamond shaped and smooth at the base. On smaller sharks, there are three to five ridges on each denticle, while there are five to six on each larger shark. There are several teeth along the posterior of the denticles, the middle of which is slightly longer than the rest. Stroking a shark from head to tail is very smooth, although from tail to head is similar to

Blacktip Reef sharks are unique organisms that appear as the way their name describes it. The sharks have black tips on its caudal and dorsal fins, as well as angled saw-like teeth and a round and small snout. Other fins that this fish has is its two pectoral fins, pelvic fin, and an anal fin. These sharks can grow to be six to seven-feet long and have white bellies and dark backs, this allows the shark to disguise itself with the obscured seafloor and the lighter ocean surface.

Their bodies are also shaped somewhat like a torpedo to give them a more streamlined affect in the in water. Yet, some types of sharks, the ocean dwellers have a flat body similar to that of skates and rays. Sharks can travel with great bursts of speed especially when attacking their prey or when excited. The fastest-swimming sharks have a moon-shaped tail that provides extra power and durability for swimming.

Although vocabulary is the sub-skill of a language, it plays a very important role in language learning and teaching. In fact, vocabulary is central to language and is of paramount importance to language learners. On the other hand, words are the building blocks of a language that are used to label objects, actions, and ideas. In other words, people cannot convey the intended meaning without knowing vocabulary. It is widely accepted that vocabulary is a very important part in English language learning because no one can communicate in any meaningful way without vocabulary. As McCarthy (1990) stated, the single, biggest component of any language course is vocabulary. Nation (1990) also affirms that vocabulary can be considered as the most important element in language learning because Learners think that many of their
