Answer: Electron Microscope is most appriopriate for studying living cells.
Explanation:
Most of the cells are so tiny that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study the behavior of cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.
The major demerits are size, maintenance, cost, researcher training and image artifacts resulting from specimen preparation. This type of microscope is a large, cumbersome, expensive piece of equipment, strongly sensitive to vibration and external magnetic fields.
When a gene is turned off, It no longer provides the directions for making proteins. this means that the proteins needed to fulfill a particular job ( let’s say, tolerate lactose ) aren’t produced.
The graph which best represents this phenomenon is graph C.
The result of disruptive selection is the selection of the most extreme phenotypes/genoypes, and the decrease of the middle terms.
It is mostly because of the temperature. It is very hot. And it is not Dwarf's in general it is white dwarfs. The surface of a white dwarf is approximately 10 times hotter than it was before the star went nova.
