The discovery of microRNAs (miRNAs) is one of the major scientific breakthroughs in recent years and has revolutionized the way we look at gene regulation.
<h3>
What is MicroRNAs ?</h3>
microRNA is the name of a family of molecules that helps cells control the kinds and amounts of proteins they make
- That is, cells use microRNA to help control gene expression. Molecules of microRNA are found in cells and in the bloodstream.
- The miRNA functions as a guide by base-pairing with target mRNA to negatively regulate its expression.

Answer:
The correct option is : a. serous fluid in the pericardial cavity
Explanation:
The heart is enclosed in a sac containing the heart, known as the pericardium. The pericardium has two layers- fibrous and serous layer.
The serous layer of the pericardium produces and secretes the pericardial fluid into the pericardial cavity.
The pericardial fluid is a lubricating serous fluid present in the pericardial cavity. It reduces the friction caused between the pericardial membranes by lubricating the epicardial surface.
Answer: A surgical puncture of the abdominal cavity to remove excess fluid is known as abdominocentesis
Explanation: Abdominocentesis is a surgical procedure carried out by a train health personnel. It involves puncturing of the peritoneal cavity of the abdomen to access fluid which is drained and used for further diagnosis. Usually the fluid is drained by gravity, a syringe or by connection to a vacuum bottle. The procedure is carried out to:
- relieve abdominal pressure from ascites.
-to diagnose bacterial peritonitis.
-to diagnose blood in peritoneal space in trauma cases.
Answer:
Explanation:
Anemia is lack of RBC in body or disfunctional RBCs. Risk factors would be things that make you prone to have this disease. Some commonly known factors are:
- Age (more common as you keep aging)
- Family history (genetics does make you less or more prone)

A head drape is used for procedures of the nose and throat. It protects the eyes during surgery and prevents hair from entering the surgical field.
A head drape is the procedure of covering the patient's non-sterile region from one that is going to be operated. The process id performed to minimize the risk of unwanted objects and the infections during the surgery.
Surgical field is the sterile, microorganisms free area where the surgery is to be performed. It consists of the draped patients, the tools and equipment that are necessary to perform the operation. Even the doctors are a part of surgery field. They must be completely covered with masks on and the hands and forearms scrubbed.
