With a light microscope one can view the nucleus and endoplasmic reticulum, large vacuoles etc
The resolution of a light microscope is dependent on the wavelength of light that is the main beam of illumination. Light has approximately 0.4 um (UV)- 0.7um (Infrared) wavelength. Organelles smaller than about 0.5 um will be difficult to discern with a light microscope.
With an electron microscope one can view, in addition, even the ribosomes and mitochondria, chromosomes, tubules etc.
An electron microscope can discern very minute details of a cell. This is because its resolution is dependent on the very small wavelength of a beam of electrons which is approximately 0.002 um (about 10,000 times powerful than a light microscope)
You observe a species of bird that, upon hatching, has contact with its parents only while being fed. You also never hear the parents sing during the feeding process. What would you propose about song production in this species of bird?
A. Song learning in this species is most likely learned behavior.
B. The period of imprinting is likely later in the bird's life.
C. This species does not hear.
<span>D. Song production in this species is most likely innate behavior.
the answer is d im pretty sure
