The third one should be correct
B) cold to hot hope this helps
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)
The answer is b because there are cracks in the ocean that are caused by two plates crashing
The asnswer is 2DG also known as 2-Deoxy-D-glucose. 2DG is a glucose molecule that has the
2-hydroxyl group replaced by hydrogen, so that it cannot undergo further
glycolysis. As such; it acts to competitively inhibit the production of
glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of
glycolysis).
