Why would osmotic pressure be low in someone who is starving?
histamines.
The pressure needed to stop osmosis is called?
The pressure needed to stop osmosis is called osmotic pressure. It is the pressure required to prevent the flow of solvent across a semipermeable membrane to achieve equilibrium.
How would a fluid with a high solute concentration affect osmotic pressure when compared to water?
A fluid with a high solute concentration would have a higher osmotic pressure compared to water. This is because the presence of more solute particles in the solution increases the pulling force required to prevent water from moving across a semipermeable membrane, leading to a higher osmotic pressure.
Changes in blood osmotic pressure would affect the levels of?
Antidiuretic hormone
Will osmotic pressure be generated if solutes are able to diffuse?
Yes, osmotic pressure can still be generated even if solutes are able to diffuse. Osmotic pressure is a result of the concentration gradient of solute particles across a semipermeable membrane, and it is not affected by the ability of solutes to diffuse.
Changes in blood osmotic pressure would most affect the secretion of?
Changes in blood osmotic pressure would most affect the secretion of antidiuretic hormone (ADH) by the pituitary gland. ADH helps regulate the concentration of urine by increasing water reabsorption in the kidneys, and its secretion is influenced by blood osmotic pressure to maintain water balance in the body.
What is the definition of osmotic potential?
What is osmotic potential?Osmotic potential is defined as the ability of a solution to suck water in if it was separated from another solution by a semi-permeable (meaning water gets through, but not the solution) membrane. This means that if you have pure water next to salt water, separated by such a membrane, the pure water would run over to the saltwater, while the water in the saltwater would stay where it is. Water, then, always moves towards a higher concentration, from high pressure to low pressure. This is also how trees get water from the roots up to the canopy, as they don't have beating heart like we do. The plants use their osmotic potential to transport water through the cells from the bottom (roots) where the osmotic pressure is high, to the top (canopy) where the osmotic pressure is low. As the water is transported up, the osmotic pressure in the roots sinks, allowing more water to run in from the soil.
What would happen to an individual playing a long game of basketball outdoors on a hot afternoon?
The osmotic pressure of the blood would decrease!
Does osmotic pressure affect seed germination?
Yes, osmotic pressure can affect seed germination. Seeds absorb water to initiate germination, and if the osmotic pressure outside the seed is too low or too high, it can hinder the water uptake process and impact germination rates. Maintaining an optimal osmotic environment is key for successful seed germination.
Is an obligate halophile an organism that requires high osmotic pressure?
Yes, an obligate halophile is an organism that requires high osmotic pressure, typically in the form of high salt concentrations, to survive and thrive. These organisms have adapted to living in environments with high salt content and would not be able to survive in environments with lower osmotic pressure.
What determines the osmotic pressure of any given solution?
Osmotic pressure of saline (0.91% NaCl w/v) is arround 0.0085 ATM.The osmotic pressure is 7.58 ATM at 25 °C. P=MRT The molarity of 0.9% NaCl is 0.155M. But it has 2 ions per formula so 0.31 mol/L * 0.082 latm/Kmol * 298K= 7.58 ATM
What is the isotonic solution for Urea?
The isotonic solution for Urea would be a solution that has the same osmotic pressure as a cell. This concentration would typically be around 0.15 M for Urea.
