What cellular structures can be observed with the aid of light microscopy and electron microscopy?​

Biology

Serjik [45]4 years ago

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)

What is the primary site on a neuron for receiving signals from other neurons?
Vedmedyk [2.9K]

Answer:

Dendrites

Explanation:

Dendrites or dendrons are the branching of protoplasmic extensions of a nerve cell. As the neurons are arranged in head to tail manner, these dendrites lie close to the axon terminals of the other neuron and thus they receive signals from the other neurons and then pass the received signal to the main body of the neuron which is also called Soma. The electrical signals are passed from one neuron to the other neurons via the synapses which are located at various points on the dendrites.

When the adaptive feature is enhanced by female choice, it is referred to as of what?
Dovator [93]

Answer:

S3xual selection as a consequence of female choice is easy to understand, provided we are willing to accept that female preferences exist. If females show a preference, then males with the preferred trait will leave greater numbers of offspring, and their trait values will tend to increase in frequency in the population.
