ADH and aldosterone secretion are part of the body's compensation for A serious hemorrhage. Vasopressin or ADH is a hormone synthesized as a peptide prohormone in neurons in the hypothalamus and is converted to AVP. The primary role is maintaining osmolarity and thus maintaining the volume of water in the extracellular fluid, and the secondary function of ADH is raising blood pressure by constricting blood vessels. Aldosterone on the other hand is essential for sodium conservation in the kidney.
They are the energy base of the food chain for all aquatic organisms, without them all aquatic organisms would most likely parish.
Answer:
secondary succession
Explanation:
secondary succession occurs after a major natural disturbance in the environment, but the soil is still there afterwards so its faster then primary.
Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.
The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.
Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells. The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
