Answer:
The flu virus changes every year.
Explanation:
The virus that causes the flu mutates rapidly. Each year, a different flu strain causes the flu, which explains why you need to get a new flu shot every year. The antibodies you produced in response to last year's flu shot won't protect you from this year's flu. It is difficult to keep up with a quickly evolving virus like the influenza virus.
Doctors recommend annual flu shots to deal with the constant evolution and mutation of flu viruses. The rapid mutation rate of the flu virus requires the development of new vaccines each year to combat emerging strains. This process allows the flu shots to help control and mitigate flu outbreaks.
Doctors recommend getting flu shots each year due to the constant evolution and mutation of influenza viruses. Each year, scientists across the globe try to predict the flu strains that will be the most widespread and harmful. This prediction is based on how flu strains have evolved over time and over the past few flu seasons.
Several viruses, such as the flu, mutate and replicate at a rapid pace. The vaccine developed to protect against last year's flu strain may not offer protection against the coming year's strain due to the virus's evolution and adaptation.
The high rate of mutation in flu viruses makes it particularly difficult for the immune system to recognize different strains. Although the body may develop immunity to one strain through natural exposure or vaccination, new strains keep emerging that the immune system won't recognize.
The virus's surface molecules mutate, causing the flu to alter sufficiently each year such that the previous year's vaccine may not protect against the coming year's common flu. Therefore, new vaccine formulations need to be derived for each flu season.
Every year, new flu vaccines are developed to be effective against the expected dominant strains. These strains are typically cultivated in eggs and used to produce either an inactivated or a live attenuated vaccine. Through this process, annual flu shots aid in controlling influenza outbreaks.

Explanation:
The acceptable macronutrient range for fat in the diet can vary depending on individual factors such as age, sex, activity level, and overall health goals. However, general guidelines suggest that fat should typically make up around 20-35% of total daily calorie intake for most healthy individuals.
The American Heart Association (AHA) recommends that:
- For a 2,000-calorie daily diet, total fat intake should be limited to 44-78 grams per day.
- Saturated fat intake should be limited to less than 7% of total daily calories, which is about 16 grams for a 2,000-calorie diet.
- Trans fat intake should be minimized as much as possible.
It's important to note that not all fats are created equal. It's recommended to focus on consuming healthy fats, such as monounsaturated and polyunsaturated fats, while limiting the intake of unhealthy fats, such as saturated fats and trans fats. Healthy fat sources include foods like avocados, nuts, seeds, fatty fish, and vegetable oils.
It's always a good idea to consult with a healthcare professional or registered dietitian for personalized dietary recommendations based on your specific needs and health goals.
The term blind sport denotes the small gap in the visual field. It is the location on the retina known as the optic disk where the optic nerve fiber exit the back of the eye. This small gap in the visual field is caused because there are no cones or rods at this point on the retina. So, the correct answer is B: It's is an area of the retina where there are no rods or cones.
Answer:
Muscular Body type
Explanation:
According to Sheldon, people with a mesomorph body type tend to have a medium frame. They may develop muscles easily and have more muscle than fat on their bodies. Mesomorphs are typically strong and solid, not overweight or underweight.
