In this study, it is aimed to adapt the English scale into Turkish and to provide evidence regarding reliability and validity. Stem arranges leaves in a way that it gets direct sunlight to perform photosynthesis. Within defined limits, cells are capable of adapting to a variety of stimuli which may upset normality. Thymus atrophy during early human development (childhood) is an example of physiologic atrophy. STEM CELLS is read and written by clinical and basic scientists whose expertise encompasses the rapidly expanding fields of stem and progenitor cell biology. Author links open overlay panel Narmin Bigdeli a Maria Andersson a Raimund Strehl b Katarina Emanuelsson b Eva Kilmare a Johan Hyllner b Anders Lindahl a. Cactus has a thick, waxy coating that prevents water loss and helps it to retain water. Plants have adaptations to help them live and grow in different areas. The stem is green, to make food for the plant. Looking at how animals have adapted to cope with all sorts of conditions. Show more. 1. . Atrophy is a decrease in cell size.
