Some samples are transparent, or very difficult to see, therefore, they are stained in order to be seen more clearly and easier to work with.

During eye surgery, the clear layer of the eye is stained to be easily extracted, if it was clear then the surgeon might cut the eye instead of just the layer.

Hope this helps, u might want to search online for more info.

With DNA and small samples of organisms they are often transparent or very difficult to see. When you are viewing samples with a microscope the samples are so small that they are near about invisible to see as they are about half a micrometer thick or at times even smaller. The sample is placed in paraphin or epoxy, allowed to harden and then cut by a glass or crystal knife. The samples are then stained and placed under a microscope for viewing. The staining process can produce brilliant and beautiful designs from the crosssamples of these organisms.

Most fat-soluble nutrients are absorbed in the Lymphatic system.

<h3>What is Lymphatic System?</h3>

A network of tissues, veins, and organs known as the lymphatic system collaborates to transport lymph, a colorless, watery fluid, back into your circulatory system (your bloodstream).

Your body's arteries, smaller arteriole blood vessels, and capillaries each day carry about 20 liters of plasma. About 17 liters are then returned to the circulation through veins after providing nourishment to the body's cells and tissues and collecting their waste products. The remaining three liters permeate your body's tissues via capillaries. The lymphatic system gathers this extra fluid, which is now known as lymph, from your body's tissues and transports it to various locations before returning it to your bloodstream.

How do the nervous system and endocrine system differ in regards to managing homeostasis?
Citrus2011 [14]
Hello friend!!
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurons, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. 
Transmission by the nervous system is short-lived but quick, whereas transmission by the hormonal system is long-lasting but takes much longer. Hene, communication is faster when using the nervous system. 
In the nervous system, responses are localised - whereas in the hormonal system, they are widespread. Responses are often permanent in the hormonal system, but temporary and reversible in the nervous system.
Hope It Helps!!All The Best!!

The signal is first reach to dendrites. From the dendrites, the signal transmit to the cell body and then to the axon hillock. The signal then transmits to the axon. At the end of neuron the message is transmitted to the synaptic terminal. The nerve impulse finally reaches to the biceps brachii and results in the flexion of the arm at the elbow.
