Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.
Contemporary landscapes result from many causes, including variability in abiotic conditions, such as climate, topography, and soils; biotic interactions, such as competition, mutualism, herbivory, and predation, that can generate spatial pattern even when environmental conditions are homogenous; natural disturbances. I hope this helps :)
Answer:a
Explanation: because naturally it occurs anytime it wants to
An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes. Do not need to compound it in the form of essay?
