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:

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
