4 When the steak has cooked to your preferred level of doneness, remove from the grill and place on a cutting board. Cover with aluminum foil to hold in the heat while the steak rests for 10 to 15 minutes. 5 Notice the direction of the muscle fibers of the steak; this is called the grain of the meat. Flank steak is a very lean cut that will be tough and chewy unless you cut it in a way that breaks up the muscle fibers.
The typical flu incubation period is between 24 hours and four days, with the average being two days. This means that if you are exposed to the influenza virus and become infected, you will start to experience flu symptoms anywhere between 24 hours and four days after the exposure. Another factor that contributes to how the flu spreads is when exactly you may be contagious.
The estimated incubation period is unknown and could range from 1 to 7 days, and more likely 1 to 4 days. Persons with novel H1N1 flu virus infection should be considered potentially contagious (able to spread disease) for up to 7 days after illness onset.he estimated incubation period is unknown and could range from 1 to 7 days, and more likely 1 to 4 days.
