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>
C. and the sandstone formed around the rocks which are most likely metamorphic
Answer:
a birds wing is made of cartilage and bones, bugs wings are made of their exoskeletons. bugs wings are called chitin
Answer:
<h2>Catabolite repression
</h2>
Explanation:
1. Catabolite repression: it is the positive control of the lac operon.
2. It results in an increase in the rate of transcription. Here, the CAP protein is activated by cAMP which then bind to the lac operon and facilitate the binding of RNA polymerase to the promoter to transcribe the genes for lactose utilization.
3. Role of glucose in catabolite repression is that It stimulates transcription from the lac operon, causing an increase in cAMP levels in the cell. Glucose decreases the levels of cAMP in the cell, result in repressing transcription from the lac operon.
