Answer:
Gene therapy
Explanation:
Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.

Answer:
Kidneys
Explanation:
The kidneys remove wastes and excess water in the body through the urine, as urine flows from the kidneys to the bladder through two thin tubes located on both sides of the bladder called the ureter, and the bladder stores urine, and each of the kidneys consists of about one million filtering units called the renal tubular unit contains Each renal tubular unit has a filter called the glomerulus and tubule, and the renal tubular unit operates through a two-step process:
glomerulus: filters blood.
Tubule: Returns the necessary substances to the blood and removes waste.
