If a child were born with a mutation that made the ascending limb of the loop of henle permeable to water, what would be the min
imum and maximum urine osmolarities the child could produce? units are in mosm. a. minimum 100 / maximum 300
b. minimum 300 / maximum 1200
c. minimum 100 / maximum 100
d. minimum 100 / maximum 1200
e. minimum 300 / maximum 300
In normal situations: -The thin ascending limb is of the loop of henle is impermeable to water. But, is permeable to ions (sodium, chloride) that cross by diffusion. -Urine osmolality should be 300-900 mOsm/kg of water.
In this case, if the <span>ascending limb of the loop of henle is permeable to water is the same as saying the loop isn't doing it's job of </span>creating a concentration gradient. Because of that, The process of reabsorption of water and creation of a concentrated urine is not correctly happening.
The answer is E<span>. minimum 300 / maximum 300 </span> The loop of Henle receives isotonic (300 mOsm/L) fluid, from the <span>proximal convoluted tubule, and since it's not working th way it should it won't change those values. </span>
Quick answer: Food enters the human digestive system through the mouth before then moving through the pharynx, esophagus, stomach, intestines, rectum and anus.
The algae increase the autotrophy by offering photosynthesis to the fungi in the lichen organism.
A lichen is an organism consisting of a symbiotic association between a fungus (the mycobiont) and algae. The mushroom brings water and mineral salts. The alga produces, by photosynthesis, various organic compounds of which it gives a part to the mushroom.
Sound is a form of Energy that produces a sensation of hearing in our ears.
Sound is produced as a result of vibration produced in a body.
Sound energy is transmitted from one place o other place by wave motion.
When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
During vibration, they collide with the surrounding particle and transfer some energy to them.
They then start vibrating faster and transferring energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
Thus, particles are an important factor in propagation of sound.
Sound cannot travel in vacuum.
It requires a medium to travel from one point to another.
A sound can travel in all medium, solids, liquids and gases as all of these have particles.
The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest in solids.
