Many people believe in it, while at the same time, many don’t. Like it or not there are many factors that point to the existence of evolution, but what role does evolution play in the theory of learning. It is obvious that learning has an important bearing on evolution. Ideas or actions that are advantageous…

Penguins are small white and black bird like creatures that live in cold regions. Penguins are the most fascinating creature around. II Explanation 1 Physical characteristics A Most penguins have a white breast and a black back and head. Many species exhibit red, orange, or yellow patches on the head and neck. Because their short…

Earthworms Earthworms are classified as Annelida. Annelida mean little rings which refers to the many segments in their body. The structure of an earthworms body is made up of more than one hundred segments separated by partitions that divide the coelum. All segments are identical except by the anterior and posterior ends. The anterior segments…

Not all animals have lungs. Many animals live in environments where lungs would be efficient enough for survival. Gills are another type of respiratory system, which are very efficient at removing oxygen from water: there is only 1/20 the amount of oxygen present in water as in the same volume of air. Gills greatly increase…

The cold expanses of Antarctica, extreme northern Asia, and Greenland are therefore true, but cold, deserts. Most commonly, however, the term desert is used for regions that are barren because they are arid, or dry. Arid deserts receive little precipitation and are characterized by specialized plants that tolerate drought conditions and salty soils, and by…

They are unique vessels to aid their water circulation. There are ferns of which offer matching decorations for your garden with their feather-like leaves. This becomes a reason to why ferns…

The fossil record doesn’t really tell much about how paired fins came about so together with his colleagues, they decided to discover whether the anatomical parallels that Gegenbaur found between the gill arches of cartilaginous fish may be like the molecular patterning mechanism in these system organs. They performed several experiments to explore more about…

Activities are widely employed to indicate antioxidant responses underlying the toxic effects of test chemicals. Yet, earlier studies mainly described the procedures as performed according to manufacturer’s instructions without modifications that are specific to any organisms. The present protocol describes the steps in analyzing the superoxide dismutase (SOD) and catalase (CAT) activities in C. elegans,…

It can be also defines as any water that has been adversely affected in quality by anthropogenic influence or else being contaminated by organic and inorganic materials ,excessive minerals and heavy metals. Untreated water generally contains the high amount of organic materials, pathogen microorganisms usually bacteria, three main nutrients (nitrogen, phosphorus and potassium), noxious, toxic…

Without the Earth we have nowhere to live, along with many other organisms. If we don’t save the Earth now maybe our children or grandchildren might not be able to see it for long. Our atmosphere is weakening and we have to do something about it fast. We could plant more trees to create more…
