Answer:
• People without any symptoms may be infected and spread the SARS-CoV-2 virus.
• Upon speaking, the virus is released into the air, the louder the more.
• The virus can remain airborne for many hours in classrooms.

Answer:
Sarah's calculation isn't correct.
Explanation:
Both milliliters (ml) and ounces (oz) are units used to measure the volume of fluid. One ounce is about 29.6 milliliters. If we multiply this by 16, we'll get about 473ml, which doesn't fit Sarah's original measurements. 473ml is obviously way less than 630ml. Her calculation would be correct if she wrote down 21.3oz (630ml ÷ 29.6 = 21.3oz).
Making physical activity fun, ex: include free games like tag, add playground time.
Answer:
B. Fatigue
Explanation:
Alarm, resistance, and fatigue are three stages of the body's response to stress. These stages are a part of the general adaptation syndrome (GAS), developed by Hans Selye.
Alarm is the first stage. It occurs when we first perceive something as stressful, which causes the body to initiate the fight-or-flight response.
Resistance is the second stage. If the stress continues, the body stays activated at a higher metabolic level, trying to counteract the persistent stress.
Fatigue is the final, third, stage. The longer the body is exposed to a stressor, the less energy it has. This can lead to suppression of the immune system and cause a variety of health issues, such as heart disease, digestive problems, depression, etc.
Thus, the correct answer is B.
