Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fishes, amphibians, mollusks, crustaceans, cnidarians, echinoderms and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition …

Summary – the theory of plate tectonics had enabled us to explain the origin of earthquakes, volcanoes, mountain building and has told us the fascinating history of the earth. To find out the evidence for all this watch “Wegener and the proof of continental drift.” Tags: digital learning, online learning, learn chemistry, school chemistry, chemistry, gcse chemistry, high school chemistry…

In this video we are going to look at what density is, how it is measured and the differences in density between the different states of matter. Informally, density is a measure of how ‘packed’ a material is with mass. Density is defined as the mass of an object per its unit volume. So the big beach ball has a small mass but a big volume, meaning it’s density is low. Whereas the pebble is…
Symmetry is an intriguing phenomenon manifesting itself in art, nature, and the mind. This Special Issue book features 19 articles about discrete geometric and combinatorial polyhedral structures, with symmetry as the unifying theme. These articles present an attractive mix of topics and have appeared in two related Special Issues of Symmetry, on "Polyhedra" in 2012/2013 and on "Polyhedral Stru…
In pregnancy, maternal nutrition sustains and nourishes the developing child. Imbalances in either the direction of nutritional excess or deficiency can have adverse consequences for child health. In addition, more research now suggests that good pregnancy nutrition influences child health beyond pregnancy and delivery. This includes modifying the risk of child health outcomes as they enter chi…
Hydrogen is a gas at room temperature, and is the first element in the periodic table. It has the chemical symbol H, but is usually found as a diatomic molecule of H2.
The technology that keeps huge cargo ships afloat is amazingly simple. PJ, a masters student in Naval Construction and Engineering at MIT, explains just how simple it really is. Resources from MIT on the technologies in naval architecture that help even the heaviest cargo ships float: https://www.pinterest.com/mitk12video...
