There are many differences between these two, the first is the skeletal system for the human is inside the body and that helps maintain the organs in place. While the skeletal system or exoskeleton is outside the body for the crayfish that helps

Chaminade proves to be one of the most challenging academic schools for many students who attend the institution. Boys, whether they are intelligent or not, usually tend to struggle at Chaminade during some point of their academic careers. Though this is true, a myriad of students succeed at Chaminade by studying hard, paying attention in class, and managing their time effectively.

Throughout the early Paleozoic and Mesozoic ages, the major sharks belonged to a set called Hybodontoidea. They had fins and bony structure

They have different predators, and sharks can be one of them. Their body is segmented and has the presence of a cephalothorax. The killer shrimp has an open circulatory system, what means that they don’t have veins, but they still got a heart that helps on the circulation. They can generate forces that are more than 1000

Pipefish are very similar to seahorses, but there are also differences. For example they look a little different, their necks are not bent, and they are very long and thin. Only a few male pipefish have pouches to hold babies like male seahorses. The rest attach the eggs to their stomach or tuck them in folds in their skin. Sea dragons

The plot revolves around them, they are the main characters. Characters are so important because they give you the main plot and conflict in the story. Being the main character in The Chrysalids David is shown threw the whole book from his childhood to his teens, we see him grow and with his growth shown threw the story a lot of sides are shown such as his emotions, action and abilities. Getting to know David threw the whole story we see what problems he runs into and situation he had to handle. Sacrifice, discovery and mistakes were situations David avoided made and ran into while he was growing up, but with the situation came change to the story providing reasons and important events in the novel.

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.

The progression of T. pallidum can be divided into four stages, each exhibiting different characteristics and symptoms. The initial stage of T. pallidum is the Primary Stage, which presents itself with sores in the place that the bacterium and disease entered the body. Round, raised sores called chancres occur but can be difficult to notice based on their location such as the genitals or anus. If an individual is treated, the chancres last 3-6 weeks. Without treatment, the disease will progress to the Secondary stage. The Secondary Stage is characterized by skin rashes that appear red or brown, and do not itch. Chancres can appear up to 6 months following infection White lesions can develop in warm and moist areas such as the mouth or groin.

Echinacea counts as one of the most popular herbal remedies come cold and flu season, though this powerhouse supplement does more than just treat the common cold and flu virus. It’s an all-around good remedy that has been used to treat conditions as diverse as ADD/ ADHD, snake bites, and eczema.

There are many different types of fish, but there are four classes: jawless fish, cartilaginous fish, ray-finned fish, and lobe-finned fish. Jawless fish have no jaw but have teeth like the lamprey. Some cartilaginous fish lose their teeth but eventually grow them back like manta rays and sharks. Finally, lobe-finned fish, which are uncommon and rare, are named after their large lobe-like fins. These fish live deep in the ocean and includes the lungfish and, the thought to be extinct, coelacanths.

This species of shark is extremely hydrodynamic due to its “sharp” pointed snout, triangular dorsal fin, and large crescent-shaped tail fin. Its coloring consists of a darker metallic blue on the top and a silver/white underneath. The average size for this kind of shark is approximately 10 feet long and 300 pounds. Although they have been caught and measured at over 12 feet and 1,000 pounds. The females of this species are typically

Like sharks, rays to have cartilaginous skeletons. They are lighter and even their skull is flattened.

Because of this body shape the skate’s eyes are positioned on the top of its head, while the mouth and gill slits are found on the bottom side. While the placement of the skate’s jaw and gills may look comical, this morphology has been expertly honed through thousands of years of evolution for the dietary needs of the ray. The rays mouth contains rounded teeth that that they use to grind food from the bottom of the ocean floor. Most fish have well discernable pectoral fins, the leopard skate’s fins resemble an elongation of the back. The pectoral fins run the full length of the skate’s body, where as a typical pectoral fin is much smaller and typically ends before the first dorsal fin. Along with comparatively large pectoral fins, skates

Jawless fish are similar to other fish expect that did not evolve with any jaw; they instead use a circular sucker-like mouth to attach and suck the blood of their prey. An example would be the sea lamprey or eels. Cartilaginous fish have jaws but their skeleton is made of flexible cartilage, they don’t have bones. Examples of these animals are sharks, skates, and rays; these organisms are often the predator hunting for their food. Bony fish are the largest class of vertebrate with about 29,000 species living in various environments like freshwater, coral reefs, and salt water. Bony fish have a skeleton made entirely of bone; they tend to have good eyesight too. These organisms have operculum which is a special flap that allows the fish to breathe without swimming by covering and protecting the gills. Salmon, cod, and sturgeon are examples of bony fish. Reptiles are a four-legged class of vertebrate who have adapted to living on land better than amphibians. These adaptions include some features like amniotic eggs, tough skin that is coated by keratin, and a respiratory system that has branching bronchial tubes within the lungs. Amniotic eggs are eggs that have amniotic fluid nourishing and protecting the embryo within the egg. Another feature that reptiles have are the capability to molt, which means they shed their outer skin, replacing it with new. Creatures that fall under reptiles are snakes, turtles, crocodiles and lizards. Amphibians are four-legged creatures that do not lay eggs with amniotic fluid; instead these eggs tend to dry out fast forcing the amphibian to lay their eggs in water. These creatures use their lungs to capture oxygen rather than using gills like fish. Amphibians interchange their environment between on land or in the water. Salamanders, toads, and frogs are examples of amphibians. Birds are

Cholas Dynasty, otherwise known as the Cholas of Tanjore, is one of the most successful dynasties of India. Little is known about the beginning of the ancient dynasty, however what is known is the dynasty came to an end around the thirteenth century. The Cholas Dynasty had a lasting impression on India, especially in the southern part. Their influence had contributed to great literature and architectural works during their rule. At their peak the dynasty ruled from Sri Lanka all the way to the Godavari basin in the north. The Cholas Dynasty had contributed to India’s history through many facets such as their art, literature and culture. The Cholas Dynasty had very influential and successful leaders as well. Perhaps the most important and most influential was Raja Raja Chola. His reign lasted from 985-1014 CE. His rule was so impactful that he made the Cholas Dynasty one of the most powerful and dominate kingdoms in India. Perhaps the greatest feature of the Chola Dynasty was its temples. Their temples are very unique because of the inscriptions that cover the temples. These inscriptions tell us about the Cholas culture and other stories about themselves as well. The Cholas Dynasty had ushered in a new age of cultural and political significance that had generated a great impact on the people who lived during the Cholas Dynasty.
