Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

This video demonstrates students measuring the acidity of water, using pH indicator paper and a pH meter. The resource includes a video and a written transcript, and is supported by the Water pH Protocol in the GLOBE Teacher's Guide. This is one of seven videos on hydrology in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Heavy-metal mines might be a tough environment to grow up in, but many microbes call them home, including viruses. A recent look at core samples from a lead and zinc mine in China revealed how viruses fit into this extreme ecosystem. Environmental factors like acidity appeared to play a big role in shaping viral communities. High acidity tends to make environments less hospitable, even for organisms that live in extreme places. That explains why less acidic (higher pH) core samples contained more viruses. Similarly, viral gene function varied with depth. Deeper and less environmentally extreme layers contained genes with conventional functions related to metabolism and structure, while surface layers largely contained genes of unknown function. Tests also detected genes that viruses might use to get their bacterial hosts to incorporate sulfur from mine runoff..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.
