Which of the following factors does not affect membrane permeability? view available hint(s) which of the following factors does not affect membrane permeability? the amount of cholesterol in the membrane the saturation of hydrocarbon tails in membrane phospholipids the polarity of membrane phospholipids temperature
The polarity of membrane phospholipids
The inner core of membranes is made of nonpolar tails of phospholipids which in turn makes the membranes impermeable for polar, large and charged substances since these substances cannot cross the non-polar inner core. The saturated hydrocarbon tails pack tightly and make membrane less permeable while cholesterol affects the membrane permeability by interacting with non-polar tails.
Higher temperatures make the membrane more fluid and more permeable while at lower temperatures, membranes are more rigid due to tight packing of hydrocarbon tails and less permeable. The polar heads of phospholipids make the inner and outer surface of the membrane. Therefore, the polarity of phospholipids does not affect the membrane permeability.
the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the grasshopper had to have consumed a plant with 5,000 calories of energy
