Painting of Edmontonia Dinosaur (Edmontonia):Edmontonia was an armoured dinosaur .The large spikes were probably used between males in contests of strength to defend territory or gain mates.To protect itself from predators, an Edmontonia might have crouched down on the ground to minimize the...

Vector generated image of Electric bench Centrifuge:A centrifuge is a piece of equipment, generally driven by an electric motor (but some older models are still spun with hand), that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. The centrifuge works...

Painting of Sea otter’s ( Enhydra lutris),Geographic Range Past distribution of the sea otter included Hokkaido Island of Japan north through the Kuril Islands and eastern coast of Kamchatka, east through the Commander Islands and Aleutian archipelago, the southern coast of Alaska, and the west...

Painting of Walruses ( Odobenus rosmarus),Habitat Walruses prefer to inhabit areas with ice floes in the shallower regions near the coasts of Arctic waterways. Their seasonal migration patterns coincide with the changes in the ice. In the winter, walruses move south as the Arctic ice expands, and...

Painting of Atlantic walrus ( Odobenus rosmarus rosmarus), Habitat Walruses prefer to inhabit areas with ice floes in the shallower regions near the coasts of Arctic waterways. Their seasonal migration patterns coincide with the changes in the ice. In the winter, walruses move south as the Arctic...

Painting of Wild type Cyprinus carpio or common carp,Habitat Although they are very tolerant of most conditions, common carp prefer large bodies of slow or standing water and soft, vegetative sediments. A schooling fish, they prefer to be in groups of 5 or more. They natively live in a temperate...

Painting of Tripodfish (Bathypterois quadrifilis), DISTRIBUTION Deep water of the Atlantic Ocean, in the Gulf of Guinea off Africa and also from the western Atlantic in the region between 35° north and 10° south latitude (includes both the Gulf of Mexico and the Caribbean).HABITAT...

Painting of Star Shaped Bacteria:In South Africa, they observed a filamentous bacterium that was star-shaped when examined in cross section. Star-shaped bacteria have been seen before (e.g., the genus Stella) and, of course, long rod shaped bacteria are common. What had never been observed was a...

Vector generated Image of Electric Centrifuge 40k Revolution:The 800D Laboratory Centrifuge is designed for rapid sedimentation of small quantities of mixture in liquid. It is widely used in the areas of scientific research and product development, such as in chemistry and biochemical...

Vector generated Image of Rock Cycle:The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. As the diagram to the right illustrates, each type of rock is altered or...

Painting of Rock cycle:The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. As the diagram to the right illustrates, each type of rock is altered or destroyed when it...

Painting of Petrobius brevistylis,DISTRIBUTION Northern Europe. Introduced into northeastern North America, perhaps on rocks used for ballast. HABITAT Cliffs and boulders along rocky seacoasts. Prefers sheer surfaces with few cracks and little loose sediment. Most abundant above the high tide...

"Painting of Spectacled eider ( Somateria fischeri) is a large sea duck, which breeds on the coasts of Alaska and northeastern Siberia. The lined nest is built on tundra close to the sea, and 5–9 eggs are laid. This species dives for crustaceans and molluscs. The winter range is poorly...

Painting of Fossil of Palm Leaf:The existance of palm fossils in the Green River Formation shows that when the sediments were deposited in this portion of the Green River Basin in Eocene time that the climate was subtropical and probably close to sea level in elevation.

Painting of Effects of Erosion:Soil is removed naturally by ocean currents, water, ice, wind or living organisms and is called erosion. This displacement of soil, mud, rock and other particles has been occurring for over 450 million years. This is a downward movement in response to gravity....
