Best Answer

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.

What do scientist use to support the scientific theory of evolution?

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.

Difference between dicots and monocots in terms of stomata number and distribution?

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.

How does surface tension helps organisms?

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 are called what?

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.
