Symbiosis is the ecological relationship between two or more organisms living closely together with some form of feeding relationship involved. The three main symbiotic relationships are: - Mutualism, where both organisms benefit. - Commensalism, where one organism benefits while the other organism is not harmed. All of them thrive off of the other organism.
Answer:
Langerhans cells (LC) are members of the dendritic cells family, residing in the basal and suprabasal layers of the epidermis and in the epithelia of the respiratory, digestive and urogenital tracts. They specialize in antigen presentation and belong to the skin immune system (SIS).
Explanation:
The cell membrane folds upon itself easily, which facilitates cellular reproduction by mitosis.
<span>The membrane is a flexible, fluid mosaic and changes shape easily to create holes for substances to move in and out of the cell. </span>
<span>The outer layer of the membrane is hydrophilic, which allows water to flow in and out of the cell easily to eliminate waste. </span>
<span>The proteins that are embedded in the cell membrane act as channels to transport substances in and out of the cell.</span>
Muscle tissue is comprised of groups of muscle cells, laid out in differing organizations depending on the muscle tissue type. For skeletal muscle tissue, the muscle tissue works together to push or pull the skeleton and move the organism conciously. For smooth muscle, the muscle tissue works together to push, pull, or constrict various structures unconciously. An example of smooth muscle is the muscles involved in pushing food through the esophagus. For cardiac muscle, the muscle tissue works together to pump the entire heart in tandem.
