El documento describe la evolución y tipos de dinosaurios. Explica que los dinosaurios evolucionaron de los arcosaurios hace 232-234 millones de años y se caracterizaban por la pérdida del hueso postfrontal y el alargamiento de la cresta del húmero. Luego enumera y describe brevemente varios tipos de dinosaurios como el arqueopterix, ornitomimo, velociraptor, gallimimo, alosaurio, diplodocus y amargasaurio, incluyendo detalles sobre sus tamaños, dietas y per
The document discusses the history and principles of cell theory. It describes how early microscopists like Hooke, Levenguk, and Purkinje made early observations of cells. In 1839, Schwann and Schleiden formulated the first principles of cell theory: (1) all living things are made of cells and (2) animal and plant cells have similar structure and composition. Later, Virchow added that cells only arise from preexisting cells. The modern cell theory includes four principles: (1) cells are the basic unit of life, (2) cells have similar composition and function, (3) new cells arise from existing cells, and (4) cell specialization leads to tissue and organ formation

Eurasian curlew (apb agm minsk 30 jan 2011)Yaugen Slizh
The document discusses the Eurasian Curlew and its rare relative, the Slender-billed Curlew. It provides key facts about the Eurasian Curlew, including its population size, IUCN status, range and habitat. It then discusses the critically endangered Slender-billed Curlew, which has a population estimate of only 50 individuals. The remainder of the document outlines ongoing international efforts to search for and locate the elusive Slender-billed Curlew, including surveys of potential habitat areas in countries where it may still exist.
Прэзентацыя заалагічнага чацвярга, які адбыўся 14 кастрычніка ў РЭЦДЮ. Гэта традыцыйнае мерапрыемства АПБ, якое ладзіцца кожны другі чацвер месяца ўжо не першы год. Расклад на 2010/2011 год можна знайсці www.birdwatch.by
