Tied to national science standards and high school biology curricula, these online lessons use multimedia formats to enhance students' understanding of evolutionary concepts.
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate , sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate .
28 sty 2019 · PBS or phosphate-buffered saline is a buffer solution that is particularly valuable because it mimic the ion concentration, osmolarity, and pH of human body fluids. In other words, it's isotonic to human solutions, so it's less likely to cause cell damage, toxicity, or unwanted precipitation in biological, medical, or biochemical research.
From single-celled organisms to giant redwoods, Life Science from PBS explores all of Earth’s life forms. Use interactive, animated activities to identify the living and nonliving components of an ecosystem, design a Venn diagram to compare the migrations of monarch butterflies and red knot shorebirds, and take a virtual field trip to a solar ...
