The transport of substance A from peritubular capillary into the fluid of renal tubule is Tubular secretion.
What is Tubular secretion?
Tubular secretion is the phenomenon of transfer of materials from peritubular capillaries to fluid of renal tubule. It is basically a process of toxins removal from blood capillaries and tissues and their active secretion into the nephrons. The nephrons are surrounded by peritubular capillaries and the exchange between nephron and blood occurs via peritubular capillaries. The tubular secretion is most active in proximal convoluted tubule (PCT). Tubular secretion is an important parameter for measuring kidney function and excretion process. It also maintains the blood pH.
Hence, the substance A that is transported from plasma of peritubular capillary into fluid of reanl tubule is said to be secreted.

Answer:
miRNAs are involved in A. transcriptional silencing
Explanation:
MiRNAs are single-stranded RNAs that are involved in gene regulation. This type of RNA allows the silencing of genes through complementarity with a transcribed RNA, thus promoting their degradation and reducing their translation levels.
Adding salt to the water increases the density of the solution because the salt increases the mass without changing the volume very much.
