This study aims to observe the morphological characteristics and identify the function characteristics of junctional epithelium (JE) tissues and cultured JE cells. amined with non contact specular microscopy with semi-automated analysis technique. What’s already known about this topic? Species may also be distinguished by their biochemical and physiological characteristics, such as their ability to metabolize certain biochemicals, or their reaction to chemical tests . PubMed. 1999; Tsujino et al. † Cutaneous warts are a … Morphology continues to be of importance in taxonomy because morphological features characteristic of a particular species are used to identify it. Mean arithmetic differences and the coefficient of variation of repeated observations were calculated to estimate precision of the technique utilized. Over a long period of time, as early humans adapted to a changing world, they evolved certain characteristics that help define our species today. Among these physical … 1997; Bodmer et al. Paraffin sections of human molar or premolar on the gingival buccolingual side were prepared from 6 subjects. Cultures of malignant cells represent an excellent and permanent material for studying the biology of these tumors as, for example, specific antigens characterization, bioactive factors produced, determination of cellular proliferation, and heterogeneity of genotypic and phenotypic characteristics (Pohl et al.

As biologists have begun to devote more attention to ecology , the identification of plant and animal species present in an area and perhaps changing in numbers in response to environmental changes has … Stander Andrology and IVF Units, Department of Obstetrics and Gynaecology, Tygerberg Hospital. Classification based on morphological characteristics, such as the size and shape of spores or fruiting structures, has traditionally dominated fungal taxonomy. Preliminary Communications. We use body size as our focal morphological variable because this trait can be logically compared among species, and because body size data are readily available for a wide variety of animal populations, both human and non-human (see Tables S1 and S2 ). 2000; Halfter et al.
