Answer:
Differences between Sympathetic and Parasympathetic
1. Anatomical: The location of preganglionic neurons of the autonomic ganglia and the extension of preganglionic and postganglionic fibers are different in these two systems;
2. Pharmacological: In the Sympathetic system we have the presence of Cholinergic fibers (Ach) and in the Parasympathetic system we have the presence of Noradrenergic fibers (NE);
3. Physiological: They act antagonistically, they rarely work harmoniously synergistically in coordinating visceral activity (balance)
Answer:
The cells are connected by gap junctions.
Explanation:
A gathering of protein channels, which permits small molecules and ions to move between the neighboring cells is termed as a gap junction. The protein channels that form gap junctions comprise two connexons, of which one is situated in the membrane of one cell that combines and aligns with the connexon of the adjacent cell.
This association produces a spontaneous pathway, which permits the small molecules and ions to pass passively from one cell to another. The gap junctions are found in all the kinds of cells, however, they are not found in skeletal muscle, RBCs, and blood lymphocytes.
Thus, the passing of the fluorescent dye from one cell to another shows that the two cells are connected with the help of gap junctions.
-Properties that can be observed without changing the identity of the object or substance
-Color, shape, size, density
Answer:
Active site and protein.
Explanation:
The two components which are often found as part of an enzyme are Active site and protein. Proteins are referred to as macromolecules or macromolecules which consists of more or one of a chain of amino acid residue. They do perform an array of functions which are within organisms.
