As with all human beings children are also “psychological and physiological” intellectual beings. Children use their senses to facilitate communication with their environment. They use their sense of sight together with light and colors as well as other visual environmental factors, to communicate. According to research studies, color carries critical importance in the development of the cognitive and motor skills of the children.
luciferin is catalysed by the enzyme luciferase to react with oxygen, releasing light. Comb jellies such as Euplokamis are bioluminescent, creating blue and green light, especially when stressed; when disturbed, they secrete an ink which luminesces in the same
In common language usage, ”fruit” normally means the fleshy seed-associated structures of a plant that are sweet or sour, and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. On the other hand, in botanical usage, ”fruit” includes many structures that are not commonly called ”fruits”, such as bean pods, corn kernels, tomatoes, and wheat grains. The section of a fungus that produces spores is also called a fruiting body.
wholly new at the time. It strongly supported Darwin’s theory of sexual selection, arguing that the obvious differences between male and female birds such as the Argus pheasant were selected by the females, pointing out that bright male plumage was found only in species ”which court by day”.The book introduced the concept of frequency-dependent selection, as when edible mimics are less frequent than the distasteful models whose colors and patterns they copy. In the book, Poulton also coined the term aposematism for warning coloration, which he identified in widely differing animal groups including mammals (such as the skunk), bees and wasps, beetles, and butterflies.
Much to our disbelief, a study published in the Art Therapy: Journal of the American Art Therapy Association 22(2) pp. 81-85 provides support that coloring mandalas or geometric patterns actually does help lower stress and anxiety levels. Nancy A. Curry, BA, completed this project while pursuing an undergraduate degree at Knox College with then associate professor, Tim Kasser, Ph.D., who is now the Professor and Chair of Psychology at Knox College.
Some animals such as many moths, mantises and grasshoppers, have a repertory of threatening or startling behaviour, such as suddenly displaying conspicuous eyespots or patches of bright and contrasting colors, so as to scare off or momentarily distract a predator. This gives the prey animal an opportunity to escape. The behaviour is deimatic (startling) rather than aposematic as these insects are palatable to predators, so the warning colors are a bluff, not an honest signal.
