Cyanobacteria are found almost everywhere; in oceans, lakes and rivers as well as on land. They flourish in Arctic and Antarctic lakes, hotsprings and wastewater treatment plants. They even inhabit the fur of polar bears, to which they impart a greenish tinge.
Amazon is initially offering FreeTime Unlimited, which costs Prime members $2.99 per month per child -- or $6.99 per family -- on the Kindle Fire (2012), Kindle Fire HD, and Kindle Fire Fire HD 8.9. If you're not a Prime member, the monthly fee jumps to $4.99 and $10.99, respectively. The name of the service is a bit oblique.
These include services with a monthly subscription fee. Kindle Freetime, for example, costs 4.99 per month per child, and provides a wide range of age-appropriate videos, apps and books. FreeTime is available only for the second generation or newer Kindle Fire model, and all Kindle Fire HD models.
