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)
Answer:
Yes, a plant can reproduce without another plant involved.
No, there is no beginning of rock cycle.
Two ways in which carbon dioxide is released into the atmosphere are burning of fossil fuels such as petrol and coal etc and respiration process.
Explanation:
This type of reproduction occurs in non seed bearing plants such as ferns and mosses etc. These plants reproduce by the formation of spores. Spore formation is a type of asexual reproduction in which only one plant is involved. In cellular respiration, glucose molecule is broken down and energy is released with carbon dioxide gas. Fossil fuels are also responsible for the emission of carbon dioxide gas after burning in vehicles and industries.
Answer:
Shark skin has been used by many cultures as sandpaper. It's kept shipmates safe in slippery-when-wet conditions. Swimsuits modeled on shark skin are said by Speedo to reduce drag by up to 4 percent. Now, research by two separate groups could lead to synthetic shark skin that would make ships and submarines faster and less expensive to operate.
