But what if you're camped in a vast expanse of snow where everything is frozen? In freezing cold weather, look for flowing water.
Profiles of microorganisms: the microbial world We should note a technical point about this tree: the comparison of ribosomal RNA gene sequences can show the possible relatedness of organisms, but other information is needed to provide the root of a tree. One of the principal modes of evolution is thought to involve gene duplication followed by divergence. The original gene retains its vital function, while the copy can change and ultimately can encode a new function. If these paralogous gene pairs can be identified by sequence similarity, then the original gene should be present in all organisms whereas the new version will be present only in the more recently derived organisms. Domains and Kingdoms The proposed universal phylogenetic tree recognises three Domains of organisms (Bacteria, Archaea and Eucarya) above the traditional level of Kingdoms. For further details and discussion, see: DM Williams & TM Embley (1996). University of California Museum of Paleontology (not on this server) What should we now recognise as Kingdoms?

Molecular Expressions Microscopy Primer: Interactive Java Tutorials - Virtual Microscopy: Magnification Interactive Java Tutorials Magnification Module This interactive Java tutorial explores the effect of increasing magnification (equivalent to changing microscope objectives) on the ability to resolve features in a sample. To operate the tutorial, first use the pull-down menu to select a sample for viewing. Next, use the radio buttons to rotate magnifications between 25X and 1000X to discover how increasing the magnification allows the microscopist to explore the details of minute features in the sample. Important Note: Once all 6 magnifications have been downloaded locally to your computer, selecting between them will become much quicker because they already exist in your browser's cache.

How Fast and High Do Birds Fly? How Fast and High Do Birds Fly? Generally birds follow the facetious advice often given to pilots -- "fly low and slow." Most cruise speeds are in the 20-to-30-mph range, with an eider duck having the fastest accurately clocked air speed of about 47 mph. During a chase, however, speeds increase; ducks, for example, can fly 60 mph or even faster, and it has been reported that a Peregrine Falcon can stoop at speeds of 200 mph (100 mph may be nearer the norm). Interestingly, there is little relationship between the size of a bird and how fast it flies. Both hummingbirds and geese can reach roughly the same maximum speeds. There is, of course, a considerable difference between the speed at which a bird can fly and the speed at which it normally does fly. Airspeeds were found to be mostly in the 10-to-40-mph range. Most birds fly below 500 feet except during migration. SEE: Wing Shapes and Flight; Soaring; Flying in Vee Formation; Adaptations for Flight. Copyright ® 1988 by Paul R.
Baltimore Oriole (east) & Celebrate Urban Birds - StumbleUpon Habitat On their breeding grounds in eastern and east-central North America, you’ll most often find Baltimore Orioles high in leafy deciduous trees, but not in deep forests; they prefer open woodland, forest edge, river banks, and small groves of trees. They also forage for insects and fruits in brush and shrubbery. Baltimore Orioles have adapted well to human settlement and often feed and nest in parks, orchards, and backyards. On their winter range in Central America, Baltimore Orioles occupy open woodlands, gardens, and shade-grown coffee and cacao plantations. They frequently visit flowering trees and vines in search of fruit and nectar. Food Baltimore Orioles eat insects, fruit, and nectar. Behavior Baltimore Orioles are agile feeders that comb the high branches of trees in search of insects, flowers and fruit. Nesting Baltimore Orioles build remarkable, sock-like hanging nests, woven together from slender fibers.
What causes the smell after rain?" Most people notice a distinctive smell in the air after it rains. It's frequently linked with spring, as the smell of fresh cut grass is associated with summer. You'll find it in a lot of poetry and also on many inspirational lists of things to be happy about. But what causes it? As it turns out, the smells people associate with rainstorms can be caused by a number of things. One of the more pleasant rain smells, the one we often notice in the woods, is actually caused by bacteria! Another sort of smell is caused by the acidity of rain. Another after-the-rain smell comes from volatile oils that plants and trees release. These are a few common rain smells, but there are also all sorts of other scents after it rains.
