a symmetrical bell - shaped curve on impact.
According to this view, early sponges sit at the base of the animal tree of life, which then forks into four other groups: comb jellies, jellyfish, primitive multicellular animals called placazoa, and another group of early
symmetrical animals that led to worms, insects, and ultimately us (bilaterians).
The can's collapse must be nearly instantaneous and perfectly

If two colliding regions of plasma have the same density, temperature and strength (but different orientation) of their magnetic fields,
symmetrical reconnection begins.

symmetrical animals, Urbilateria is the forebear of spiders, snails, insects, amphibians, fish, worms, birds, reptiles, mammals, crabs, clams — and yes, humans.
Distant cousins — cockroaches and humans — could have inherited the basic blueprint from a common ancestor, Urbilateria, the last common forebear of all bilaterally
symmetrical animals.
Aliens might still be flummoxed by the message's content, but they'd be able to see
symmetrical forms in the correctly reconstructed image, letting them know they were correct in putting it together.
In a study published in Frontiers in Evolutionary Neuroscience last May, Falk reports that the brain exhibited «an unusual mixture of

If a cell is under stress, Bax proteins deposit on the surface of mitochondria in
symmetrical pairs.
Women preferred the odors of more
symmetrical men when in the fertile portions of their cycles.
Using a microscope, Backwell could see traces of the stone used to whittle a pinkie - size arrowhead into a highly
symmetrical point.
The UCLA meta - analysis likewise showed a large shift in women's preference for the body odor of
symmetrical men, although more studies are needed to determine whether this effect is robust.
Software detects this motion by analysing the movement of each pixel between different frames of crowd video footage — highly
symmetrical pixel motions indicate swaying.
For decades, astronomers have suspected that planetary nebulae — dazzlingly colorful shrouds of gas cast off by dying stars — owe their weird but often
symmetrical shapes to the sculpting magnetic forces of two stars orbiting each other at the nebula's center.
The color scheme was initialized in the first frame using a radially -
symmetrical color gradient from the animal pole to the periphery of the blastoderm.
The remarkable fins also presented a puzzle: unlike the hands and feet of land animals, they were
symmetrical.
Around 1.5 million years ago, ancient humans suddenly began to create
symmetrical tools with carefully worked edges.
However, grigs and common crickets both use two
symmetrical forewings for creating sound, while bush - crickets have a strong asymmetry between their forewings and use different wing areas for sound production.
Wilder insisted that conditions like cyclopia and diprosopia should not be considered deformations, but rather «
symmetrical anomalies on either side of a normal being».
The minor branches, however, are not usually as
symmetrical.
This work helps to explain why all particles are not always
symmetrical, including making a differentiation between particles and their antiparticles.

«Once the danger had gone,» Charlie says, «they relaxed into a gloriously
symmetrical pose, in the middle of a curved rock, under a symmetry of clouds, crowned by a perfectly positioned small cloud at the top.»
The discovery sheds light on a question that has long puzzled scientists: how did this fish, thought to be so closely related to land animals, come to have fins that are
symmetrical when our hands and feet are asymmetrical?
Recent fossil discoveries have shown that hands and feet evolved from an extinct ancestral fish with asymmetric fins, but the question of how the coelacanth got
its symmetrical fins remained.

Also important in identifying the hole gas was the almost -
symmetrical way in which Eom assembled the various layers — something like a club sandwich.

symmetrical structures.
Symmetrical lasers are required, through which electrons can pass in both directions.
