CHAPTER ONE INTRODUCTION Croton is an extensive flowering plant genus in the spurge family‚ Euphorbiaceae‚ established by Carl Linnaeus in 1737. The plants of this genus were described and introduced to Europeans by George Eberhard Rumphius. The common names for this genus are rush foil and croton‚ but the latter also refers to Codiaeum variegatum. The generic name comes from the Greek κροτον (kroton)‚ which means "tick" and refers to the shape of the seeds of certain species (Gledhill‚ 2008).

Organisms are open systems that interact continuously with their environment. The study of the interaction between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from

Hydrogel based controlled release formulations: Designing considerations‚ characterization techniques and applications. Abstract Hydrogels have evolved over the last decade as materials of choice in varied biomedical applications. This is associated with the inherent biocompatible nature of the hydrogels. The modulation of the properties of the hydrogels is easily possible due to the availability of polymers of varied chemistry and physical properties. This review discusses the pharmaceutical

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:
