<span>Cells are difficult to see in light microscopy,so to help visualize the structure of cell ,dyes are used to impart a particular color to cells.
Eukaryotic cells have both acidic and basic components so,
Hematoxylin and Eosin staining is the standard method of staining used for an eukaryotic cell.
Hematoxylin is a basic dye that binds to negatively charged DNA and RNA and is blue in colour.Eosin is pink in color and it binds to positively charged particles like the mitochondria and other components of cytoplasm.</span>
The system of glands, tissues, and cells that helps control body functions by releasing hormones is the ENDOCRINE SYSTEM. It is a collection of different glands that produces the hormones needed in the body for different functions. Hope this helps. Have a nice day.
Complementary nature of structure and function.
There is no carbon dioxide balance in biomass output or input. There is no dynamic equilibrium since carbon dioxide is being released at various rates. Geologically carbon dioxide concentration was very high for a long time and high enough to preclude evolving oxygen breathes until when carbon dioxide was locked up in plant life and oxygen levels raised by cyanobacteria and algae.
Oceans release carbon dioxide or it absorbs less carbon dioxide which causes a rise in temperature which feeds back. More heat is lost through evaporation which is lost to upper atmosphere then land biomass starts to pick up.
Most preganglionic fibers in the sympathetic nervous system synapse with postganglionic neurons.
<h3>
What is preganglionic fibers?</h3>
Fibers from the central nervous system (CNS) to the ganglion found near the vertebral column are known as preganglionic fibers.
<h3>What does preganglionic fibers synapse with?</h3>
The preganglionic nerve fibers synapse with the postganglionic neurons inside the sympathetic ganglia.
Thus, we can conclude that most preganglionic fibers in the sympathetic nervous system synapse with postganglionic neurons.
