Semi solid pharmaceutical system comprise a body of product ,which when applied to skin or accessible mucous membranes tends to alleviate or treat a pathological condition or other protection against harmful environment.. Test 2: Amphibians and Reptiles:. Objective 1: Describe the characteristics of Modern Amphibians. Objective 2: Describe characteristics of the following orders: (. Apoda. , . Urodela. , . Anura. ). Give examples of each.. Amphibians are eukaryotic, heterotrophic vertebrates. They have thin, smooth, moist skin. Some of them have fish-like scales and none of them have claws.. They are ectothermic (coldblooded).. They have external gills and lungs.. Adaptations to Meet Challenges of Life on Land. Challenges of Life on Land vs. Water. Adaptation to Meet Challenge . Air much less buoyant than water so must move against gravity. Limbs develop;. skeletal and muscle systems become stronger. Sinfield-Albets. Toler. Amphibians. The First Terrestrial Vertebrates.
