Answer:
90%
Explanation:
When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.
Treatment consists of self care and bronchodilators
Asthma can usually be managed with rescue inhalers to treat symptoms (albuterol) and controller inhalers that prevent symptoms (steroids). Severe cases may require longer-acting inhalers that keep the airways open (formoterol, salmeterol, tiotropium), as well as oral steroids.
Medications
Bronchodilator, Steroid, and Anti-inflammatory
Self-care
Quitting smoking
Supportive care
Oxygen therapy
Tbh I don’t think there is a cure, just use inhalers

Answer:
The answer is- Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure
Explanation:
The sympathetic nervous system (SNS) is a branch of the Autonomic Nervous System (ANS). Sympathetic Division of the ANS responds to threats- to fight or to run away. The stimulation of the sympathetic nervous system causes vasoconstriction of most blood vessels, including those of the digestive tract, skin and the kidneys.
It does the following;
- Increases the rate and strength of contraction of the heart
- Dilates the bronchioles of the lungs
- Decreases movement in the stomach and intestines (decreasing GI peristalsis)
- Increases the breakdown of glycogen and release of glucose from the liver thereby increasing blood glucose
- It dilates the pupil
- increases sweat secretion from the sweat glands
- constricts blood vessels of the skin
- Dilates blood vessel of the skeletal muscle
- Constricts blood vessels of internal organs except the heart and the lungs.
- Relaxes the muscle wall of the urinary bladder
- Stimulates hormone (epinephrine and norepinephrine) secretion from the adrenal medulla
NOTE: GI is Gastrointestinal tract
