What is the juxtaglomerular complex? a system for diluting urine a system for concentrating urine a system that protects the nephron from some chemicals found in blood a system that regulates the rate of filtrate formation and systemic blood pressure?

The juxtaglomerular complex is a system that regulates the rate of filtrate formation and systemic blood pressure. This is made up of the distal convoluted tubule and the glomerular afferent arteriole. In the distal convoluted tubule, there are specialized epithelial cells (macula densa) that detect sodium concentration of the liquid in the tubule. Because of the increase in sodium, the macula densa cells activate the afferent arteriole’s contraction, which reduces blood flow in the glomerulus. In the afferent arteriole, there are juxtaglomerular cells which secrete renin when the blood pressure decreases.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
