The model that showed different degrees of coiling in metaphase chromosomes using electron microscopy was called Folded Fibre.

Electron microscopy:  A microscope that uses an accelerated electron beam to illuminate is called an electron microscope. Since the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes can disclose the structure of smaller objects and have a higher resolving power than light microscopes. A scanning transmission electron microscope has achieved more than 50 pm resolution in annular dark-field imaging mode and magnifications of up to roughly 10,000,000. In contrast, conventional light microscopes are limited by diffraction to about 200 nm resolution and usable magnifications below 2000.

Based on what you now know about the relationship between limestone and marble what can you say about metamorphosis?
Fittoniya [83]

Answer:

The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock

Explanation:

This layering is a result of the process of metamorphism. Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
fgiga [73]

Answer:

The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.

It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.

In addition to charles darwin, who also proposed a theory of evolution prompting darwin to publish his origin of species?
dusya [7]
Alfred Russel Wallace, a biologist, naturalist and anthropologist who studied life in the tropics of Indonesia came up with the same idea of natural selection as Charles Darwin and prompted Darwin to publish his Origin of Specie sooner rather than later. He also studied the geographic distribution of species and as as well he was a social activist who criticized capitalism and warned of damage to the environment from man's economic activities.
