Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase.

Answer:
The correct answers is: I would predict that animals with longer loops of Henle would be able to concentrate their urine more than animals with shorter loops, and thus they would more likely survive in desserts and other dry areas.
Explanation:
The<em> Loop of Henle</em> is a tubule system that connects the proximal convoluted tubule to the distal convoluted tubule in a nephron, the functional and structural unit of the kidney. Its primary job is to establish a concentration gradient in the kidney's medulla by creating a high urea concentration deep in the medulla using a countercurrent multiplier system that uses electrolyte pumps. Through this mechanism, <u><em>water is reabsorbed to concentrate the urine and impede dehydration</em></u>.
The length of the loops of Henle is of great importance for the countercurrent multiplier system - <u>the longer they are, the more concentrated the urine can get</u>. Therefore, animals with longer loops can survive better in habitats where there is not much water around.
Gene Therapy is the name of the process.
