Answer:
It is a beneficial mutation.
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA. Mutations can beneficial, neutral and harmful or deleterious. When change in the nucleotide sequence of DNA a mutation enhances the effectiveness of a protein or improves the protein function, it is said to be beneficial. When a mutation causes the synthesis of a protein which have the same amino acid as the original protein and performs the same function as the original protein, it is said to be silent or neutral. When a mutation results in the synthesis of a protein with an altered amino acid sequence and a nonfunctional protein, it is said to be harmful.
Answer:
Juxtaglomenular is a structure in the kidney which regulates the function of each nephron, the functional units of the kidney. The main function of the juxtaglomerular cells is to secrete renin in response to:
Stimulation of the beta-1 adrenergic receptor
Decrease in renal perfusion pressure (detected directly by the granular cells)
Decrease in NaCl concentration at the macula densa, often due to a decrease in glomerular filtration rate
Explanation:
The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and a structure in the kidney that regulates the function of each nephron, the functional units of the kidney.
