What is the advantage of the increased surface area in the small intestine?
Simply to increasing the efficiency of digestion and absorption.
Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
It should. The permeability of a membrane defines how fast substances move across a membrane from a high concentration environment to the lower concentration environment. The more permeable the membrane the sooner equilibrium is reached when the concentrations on both side are the same.
What are two ways of making electromagnets stronger?
1. By increasing the number of turns of coil wound 2. BY using cores B = Ur Uo n I Here magnetic induction B is equated to relative magnetic permeability Ur of the core material and Uo the magnetic permeability of free space. N- the number of turns on the coil and I the current passing
Calcium reabsorption by the kidneys is promoted by the hormone?
Parathyroid hormone not only increases the re-absorption of calcium from the kidney but it also helps absorption in the intestines by increasing the production of vitamin D activation which also occurs in the kidney.
How does the luminosity of a blackbody vary with its surface temperature?
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
Does using fertilizer increase soil absorption?
It will limit soil absorption more than increasing it.
What has tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area?
Villi are tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area.
Why does cholesterol lower membrane permeability?
It sticks to the phosphate heads, preventing motion and increasing hydrophobic reactions.
What is the meaning of vasopressin?
vasopressin is an antidiuretic hormone responsible for increased permeability of the distal tubules of the kidney, increasing water reabsorption and reducing urine volume.
How do villi of the small intestine increase the rate of nutrients absorption?
By increasing the surface area of the intestinal wall.
What does an increase in water insoluble fiber do to the absorption rate of cholesterol?
Increasing fiber intake lowers blood cholesterol.
What is the advantage of the increased surface area in the small intestine?
Simply to increasing the efficiency of digestion and absorption.
Which ingredient found in coffee and cola can decrease calcium absorption?
Caffeine: Caffeine has a small effect on calcium absorption. It can temporarily increase calcium excretion and may modestly decrease calcium absorption, an effect easily offset by increasing calcium consumption in the diet.
How does the renal system works to maintain an appropriate level of fluid in the body?
Antidiuretic Hormone is made in hypothalamus (posterior pituitary gland). Stimulated by dehydration and increased blood osmosis. It acts on the collecting duct of nephron to increase amount of aquaporins, thus increasing water permeability. When increased water is reabsorbed, blood osmolarity decreases. Therefore the urine becomes more concentrated.
How is the leaf adapted to doing his job?
With regards to its shape, leaf has a flat surface area, increasing its rate of absorption of sunlight.
Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
It should. The permeability of a membrane defines how fast substances move across a membrane from a high concentration environment to the lower concentration environment. The more permeable the membrane the sooner equilibrium is reached when the concentrations on both side are the same.
How does the relative permeability of a ferromagnetic material vary with magnetomotive force?
There are a lot of subtle things associated with the answer to this question, but it might be best to answer by saying that with increasing magneto-motive force (MMF), the permeability of the material doesn't really change that much until the magnetic saturation of the material is approached.
