Light microscopes have a lower resolution because the refracted light waves spread out which make the image a bit blurred. Also, light microscopes can’t magnify as well as election microscopes. To observe internal structures with a light microscope, you usually need to use dyes. Hope this helped!
Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.
Answer:
B. polyphyletic group
Explanation:
Polyphyletic group is a taxon which comprises of organisms which are unrelated and do not share a recent or immediate common ancestor. Polyphyletic group is often used to refer to a group of organisms with similar characteristics called homoplasies, but not inherited from a common ancestor. This means that the organisms are of multiple origins irrespective of the traits that make them similar.
Therefore, from the question, because we do not consider ourselves fish, we would describe the group "fish" as polyphyletic.
