In medical sciences, the movement of solid particles (solute) from an area of greater to lesser concentration is called by DIFFUSION.
A random passage of particles always occurs from a place of higher concentration to another of lower concentration. This happens until the distribution of the particles is uniform. From the moment the equilibrium is reached, as exchanges of substances between two media become proportional.
The passage of substances through cell membranes involves several mechanisms, among which we can mention:
✴ Passive transport (no loss of energy)
➡ Osmosis;
➡ Simple diffusion;
➡ Facilitated diffusion.
✴ Active transport (with loss of energy)
➡ Sodium and potassium pump
✴ Endocytosis and exocytosis
➡ Pinocytosis
➡ Phagocytosis

Answer:
The answer is E. Sodium, potassium, and chloride ions but not water.
Explanation:
The thick segment of the ascending limb of the nephron loop is permeable to: sodium, potassium and chloride ions, but not water.
In this ascending branch are specific ionic channels for each of them. This ascending area of the henle handle is continued with the distal contoured tube where reabsorption and ion secretion occur again to further converate the urine.
Answer:
In addition to fighting fires, firefighters also treat sick or injured people, report to car accidents, extricate people from damaged motor vehicles, and assist at hazardous materials spills.

Answer:
Different types of intercellular junctions, including plasmodesmata, tight junctions, gap junctions, and desmosomes. Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. Tight junctions are located within our body's epithelia. Epithelia is the plural of epithelium. Epithelium is a word that refers to the covering of the body's internal and external surfaces. This includes organs (such as skin), blood vessels, and cavities. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Desmosomes are prominently found in cardiac muscle
