In Islamic law, marriage legalizes sexual intercourse between the husband and wife. Marriage is not restricted to a platonic relationship nor is it only for procreation. Marriage is greatly encouraged in Islam, partially because it provides a lawful institution in which to fulfill oneâs sexual urges.nder Islam, sexual intercourse is regarded as a loving act within marriage and should only be by mutual consent. There is, however, no explicit concept of rape within marriage in Sharia; a wife is deemed to have accepted conjugal relations as part of the marriage contract.
Amphibians are cold-blooded animals, meaning they do not have a constant body temperature but instead take on the temperature of their environment. They have moist, scaleless skin that absorbs water and oxygen, but that also makes them vulnerable to dehydration (loss of bodily fluids).
Amphibians are vertebrate animals residing in a wide range of habitats, such as aquatic, terrestrial, and arboreal. Evolution of the earliest amphibians took place in the Devonian period; their features modified over a period of time. While some are extinct, following are the characteristics of the extant species of class Amphibia. Â» The color of the skin of amphibians is a result of three layers of cells called chromatophores. 1  Deepest layer is made up of melanophores. 2  Intermediate layer consists of guanophores giving the organism the blue-green color.  Topmost layer consists of lipophores, which give the yellow color to the organisms.
