El documento describe los componentes básicos de un ecosistema, incluyendo productores, consumidores, descomponedores y factores abióticos como materiales, energía y espacio. Explica que un ecosistema está formado por las interacciones entre estos componentes bióticos y abióticos en un área geográfica específica, y que la energía que impulsa la mayoría de los ecosistemas proviene principalmente de la luz solar.
This document provides information about leadership and instructional teams at James River High School. It lists the names of team members in various subject areas and roles. It then states the school's primary goal is to establish a coordinated school-wide approach to improve literacy for all students using the Strategic Instruction Model and Content Literacy Continuum. It briefly describes these tools and strategies for teachers and students to promote content mastery and independent learning across different literacy levels.
The document discusses Barack Obama's 2008 presidential campaign platform and policies on several issues. It provides polling data showing Obama leading in key swing states. It summarizes Obama's plans to boost the economy by providing tax cuts and relief for middle-class Americans and investing in green jobs.

Virtual learning environments (VLEs) are web-based programs that help people learn various topics. A VLE provides tools for assessment, communication, content uploading, student work submission, peer assessment, student group administration, grade collection and organization, questionnaires, tracking, and more. Features include wikis, blogs, RSS feeds, and 3D virtual learning spaces. VLEs allow for quick and simple learning that is accessible anywhere at any time. They present lessons through diagrams, text, and interactive sections to aid learning. VLEs also track time spent and module completion.
This document discusses the early development of gel electrophoresis techniques by Arne Tiselius in 1937 for separating and analyzing proteins and nucleic acids. It introduces the use of agar and polyacrylamide gels as well as agarose gels for electrophoretic separation and describes obtaining results from gel electrophoresis experiments.
This document discusses the status update of Hadoop running over Ceph RGW with SSD caching. It describes the RGW-Proxy component that returns the closest RGW instance to data, and the RGWFS component that allows Hadoop to access a Ceph cluster through RGW. Performance testing shows that avoiding object renames in Swift reduces overhead compared to HDFS. The next steps are to finish RGWFS development, address heavy renames in RGW, and open source the code.
El documento clasifica los principales grupos de vegetales. Incluye cuatro divisiones principales: Briofitos, Pteridofitos, Gimnospermas y Angiospermas (que se dividen en Monocotiledóneas y Dicotiledóneas). Provee ejemplos de familias y géneros comunes dentro de cada categoría, como las Poáceas, Liliáceas y Arecáceas entre las Monocotiledóneas, y las Rosáceas, Fabáceas y Brasicáceas entre las Dicotiledóneas.
