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:
Is characteristic of Diabetes.
Explanation:
Diabetes is a disorder in which blood sugar increases due to the fact that there is mechanism by which sugar enters the cell is somehow affected.
There are different types of this disorder, the most common ones are the following,
1. Diabetes type 1, is an autoimmune disorder in which the cells that are in charge of producing insulin are destroyed, as a consequence there is not enough insulin (responsible for allowing the glucose channels to open and transport glucose into the cell). Therefore, sugar remains in blood circulation. When glucose levels are too high, it starts filtering through the kidneys and ends up in the urine.
2. Diabetes type 2, is triggered by different factors, there are genetic and environmental factors that trigger this disease. In this case, cells are 'resistant' to the insulin effect, so the body reacts by secreting more insulin. As a consequence, cells in charge of secreting insulin are overworked and at the same time, the body cells keep on increasing the resistance to insulin. There is a point in which this compensation fails to work, and blood sugar rises. When the levels become high, glucose starts filtering through the kidneys and ends up in the urine.
There are more types of diabetes, such as gestational diabetes or LADA. In this cases the cause of the disease varies, but the outcome is the same, increased blood glucose levels and presence of glucose in the urine.
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells. Cells often contain hundreds of mitochondria
