Answer:
c. creates a high osmotic pressure in the medulla
Explanation:
Loop of henle is a nephron the runs from proximal to distal convulated tubule. It create in the medulla an area of high urea concentration using energy to create the concentration gradients. Henle of loop is divided into four compartment.
1. thin ascending limb of loop of henle- it is highly permeable to water
2. thin decending limb of loop of henle is not permeable to water but Ion
3. ascending limb of loop- reabsorbtion of calcium, sodium and potassium ion from urine takes place here
4.Cortical thick ascending limb- It drains urine into distal convulated tubule.
Answer:
Due to absence of predators.
Explanation:
The populations of invasive species grow rapidly because of the absence of predators that can control its population as as result, it disrupt the whole ecosystem. Change of climatic conditions of the area where they live causes them to migrate from its original place to a new region where the invasive species have no predators to control its population but mostly humans are responsible for the introduction of invasive species. In most cases, the introduction of invasive species happen due to human activities.

I'm not entirely sure, but I think it is B) the pulley.
