On a particularly busy day, a student taking anatomy and physiology i does not have anything to drink from 9: 30 am until 6: 30 pm. osmoreceptors in the brain detect the decreased level of water in the blood. these receptors send a signal to the hypothalamus/posterior pituitary, which stimulates the release of antidiuretic hormone (adh). this hormone acts on the nephron tubules and collecting ducts in the kidney to increase reabsorption of water, which returns that water to the blood. this retention of water has the additional effect of decreasing urinary output. as the fluid levels in the blood stabilize, the release of adh ends.

Full.Q

On a particularly busy day, a student taking Anatomy and Physiology I does not have anything to drink from 9:30 am until 6:30 pm. Osmoreceptors in the brain detect the decreased level of water in the blood. These receptors send a signal to the hypothalamus/posterior pituitary, which stimulates the release of antidiuretic hormone CADH). This hormone acts on the nephron tubules and collecting ducts in the kidney to increase reabsorption of water, which returns that water to the blood. This retention of water has the additional effect of decreasing urinary output. As the fluid levels in the blood stabilize, the release of ADH ends. 1. What is the variable monitored by this loop? 2. What is the stimulus? 3. What is the control center? 4. What is the effector? 5. What is the efferent pathway? 6. This is an example of_(positive / negative) feedback. How could you tell

1, variable- the water potential of the blood.

2.Stimulus-Drop in the water potential of the blood below the set point value

3. Hypothalamus with the osmoreceptors; the hypothalamus coordinate  both hunger(at the satiety center) and thirst stimuli.

Explanation:

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
