A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
<h3>What is antigenic drift?</h3>
Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).
For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.
Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

Answer: Carbon-14
Explanation:
Carbon dating the procedure which is used for the substances which is used to date the substances less than 40,000.
This method is based on an unstable isotope of carbon that living animals and plants incorporate inside it.
When the organisms are alive the ratio of stable isotope inside the organism is same to the ratio that is found in the atmosphere.
As the organism dies the carbon 14 gets converted into nitrogen 14. By measuring both the ratios, the relative age can be determined.
Answer:
Checking the patency of the nasogastric tube
A nasogastric tube is used after surgery to decompress the stomach and limit tension on the suture line. As another means of limiting pressure on the suture line, oral feedings should not be implemented in the immediate postoperative period when the nasogastric tube is in place. Vomiting indicates obstruction of the nasogastric tube; this is why the initial action should be to check the patency of the tube. It is too soon for signs of infection to occur.
