Plate tectonics.
As the continents broke apart, the organisms on the continents drifted with them. That's why Gondwanian and Laurasian fauna are still decidedly different.
Water is lost from the gas exchange surface of terrestrial organisms because gases must be exchanged with air. Terrestrial organisms have a high water potential, therefore when the gas exchange occurs water will be lost.
the classifications are plankton , nekton, and benthos
Webbed feet, elbows, shoulders, adequate musculatory system and skeleton/exosceleton, proper breathing apparatus, blows fire from some hole in the body, and finally a set of angel wings complete with XBOX 360 H.A.L.O. Not affiliated.
The superior surface of the foot is also called the dorsal surface or the dorsum pedis.
The organisms living in the water come out for respiration, So crocodile keep its snout out of water while resting for taking in oxygen and give out carbon dioxide.
evidence for evolution
Fossil distribution, sub-surface fit of continents, geological provinces. distribution of plant and animal species, tectonic plate movements...
Generally, the evidence from geology; the earth's age and the continental drift theory to explain the distribution of organisms about the earth's surface. Genetics. All organisms on earth are linked by using the same genetic code. Evolutionary development. The finding recently of the great genetic similarity, same genes, among organisms, just many different ways to control development with master control genes in embryos. Physics. The age of the earth and ingenious rock ages that are found above and below fossils so they can be dated accurately. Homology. The bones in the forelegs of your dog match the bones in tour arm very well and strongly suggest common ancestry. This just scratches the surface of the supportive evidence for evolutionary theory.
Yes. That is so because of the: color materials (minerals) and organisms.
the composition of ice cores
We don't know that they do. Evidence of running water some time in the past has been found on the surface of Mars, but as yet no direct evidence of the past or present existence of micro-organisms.
Their evidence comes from rocks at earths surface.
Where ever there is water, ther is a good possibility for living organisms
In monocot leaves stomatal distribution is almost evenly on the upper and lower surface of the leaf. In herbacious dicot stomata is distributed more on the lower surface than the upper surface. Lastly in woody dicot there is not stomatal distribution on upper surface but great distribution on lower surface of leaves.
all the organisms die under a sophisticate surface of many different amounts of sizing potential
Surface tension helps organisms in the sense that it allows for a wide variety of biological phenomena. For instance, some water insects are able to walk on water due to surface tension.
Organisms that are permanently attached to a surface, instead of being able to move freely, are called sessile. Plants, mussels and barnacles are examples of sessile organisms.
