Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.
Answer:Hand hygiene.
Use of personal protective equipment (e.g., gloves, masks, eyewear).
Respiratory hygiene / cough etiquette.
Sharps safety (engineering and work practice controls).
Safe injection practices (i.e., aseptic technique for parenteral medications).
Sterile instruments and devices.
Clean and disinfected environmental surfaces.
Explanation:
Answer: Measures the antigen levels on the cell surface
Explanation: Fluorescence-Activated Cell Sorting. Fluorescence-activated cell sorting (FACS) measures the antigen levels on the cell surface quantitatively. Cells are dyed with a fluorescent antibody, then placed in a stream of liquid which passes the focus of a laser, and each cell emits light.
Answer:
D. ADH
Explanation:
ADH also known as the antidiureitc hormone is secretated in response to low production. The angiotensin II (produced in the lungs) increase the volumen os ADH. As its name says this hormone avoids the water losses in the kidneys in order to do that ADH associates with the AVPR1A recpetors, those receptors open calcium compartiments inside the cells, once opened the vessel constrictions starts avoiding the water losses. Those receptos also stimulates platelet aggregation and coagulation factor VIII, by this way the ADH also avoid hemorrhages.
