Answer: Food terrorism
Explanation:
Any unintentional or deliberate contamination of food which csn have an effect on human health is food terrorism.
Food terrorism can be threat whereby the food that's meant for people to.eat is contaminated deliberately with biological or chemical agents in order to cause injury or death to people and thereby disrupt the social or political stability.
Answer:
A. epinephrine
Explanation:
Bronchial constriction usually involves the tightening of the smooth muscles which surrounds the tube-like bronchial airways. This occurs via extra mucus production, spasming of smooth muscles, or swelling/inflammation of layers within bronchi or bronchioles. Bronchial constriction typically results in symptoms of wheezing, coughing and shortness of breath.
This can be treated via the use of the hormone epinephrine, a bronchiodilator. For some cases like asthma, epinephrine in small aerosolized (inhaled) doses can lead to the <em>temporary</em> relief of symptoms. Epinephrine acts by making bronchial tubes wider to allow the passage of air.
In the body, smooth muscle cells in the veins, arteries and heart are under the control of epinephrine receptors called β2 receptors. Epinephrine binding to the receptor triggers a cell signalling cascade that activates β2 receptors to dilate smooth muscle in the lungs.
Here's how-
- Calcium is essential to mediating muscle cell signalling and thus contraction
- in the lungs, epinepherine-β2 receptor binding leads to enzyme activation (adenylyl cyclase)
- conversion of the energy molecule ATP to the secondary messenger molecule cyclic AMP.
- cAMP inhibits the activity of the enzyme <em>myosin light chain kinase </em>(MLCK) in smooth muscle
- ∴ the enzyme remains inactive and the muscles relax
<em>Summary:</em><em> epinephrine → muscle relaxation →</em><em> bronchial dilation (reduced diameter) </em><em>→ decreased respiratory distress → easier breathing.</em>
Situation
1st link in the accident chain; can be changed to break the chain (ex. Someone is running late for work so he rushes outside to the car.)
Unsafe Habit
2nd link in the accident chain; can be changed to break the chain (ex. He didn't keep an ice scraper in the car and didn't warm up the car ahead of time.)
Unsafe Action
3rd link in the accident chain; can be changed to break the chain (ex. He drove off in his car with frost still covering the windshield.)
Accident
4th link in the accident chain; can be prevented by changing any of the first 3 links (ex. He hits another car because he didn't see it coming.)
Result
5th link in the accident chain; can be prevented by changing any of the first 3 links (ex. He fractures & dislocates his shoulder.)
Wrong, everything you do is because of a mindset.
