Since 1901, global precipitation has increased at an average rate of 0.10 inches per decade, while precipitation in the contiguous 48 states has increased at a rate of 0.20 inches per decade. Some parts of the United States have experienced greater increases in precipitation than others.
Answer and Explanation:
Ergotamine has been used for over 50 years and was the first specific drug to treat migraine attacks. Its therapeutic effect is due in part to its ability to contract the vessels. It is a vasoconstricting alkaloid used in migraine attacks, when treatment with non-steroidal anti-inflammatory drugs has no effect.
The mechanism of action of ergotamine is complex. The molecule has structural similarities to neurotransmitters such as seratonin, dopamine and adrenaline, and can therefore bind to various receptors and function as an inhibitor. Its use in the treatment of migraines is due to its vasoconstrictor effect of extracerebral intracranial blood vessels through their binding to the 5-HT1B receptor and inhibition of neurotransmitter binding.
Overuse of ergotamine may cause nausea, vomiting (to direct effects on the Central Nervous System in the vomiting centers) , malaise, headache, constriction of peripheral vessels and more severe effects such as ischemia of the extremities.
Ergotamine poisoning is called ergotism.
Ergotamine should not be used in patients with peripheral arterial or venous vascular insufficiency, ischemic heart disease, cerebrovascular disease, systemic infection and hypertension without effective control.
Warm up exercises are important because they reduce the risk of injury.5 points that are important for warming up are :-
1) Warming up helps the body to deliver oxygen to the travail muscle groups.
2) Warming up will increase vital sign, that reduces the prospect for muscle and sinew injuries.
3) A five minute readying will increase blood flow to the travail muscles. A larger level of blood reaching the muscles concerned within the activity aids within the delivery of the vital fuels (e.g., glucose and free fatty acids) needed for energy production.
4) Warming up will increase the suppleness of the muscle, thereby enhancing the mechanical potency and power of the travail muscles.
5)An applicable readying prepares the vascular system for the approaching (more strenuous) physical activity. Warming up helps to confirm that the cardiovascular system (heart and blood vessels) is given time to regulate to the body’s enhanced demands for blood and oxygen.

Answer:
Answer: CCB
Explanation:
A calcium channel blocker, such as diltiazem, is indicated for the management of Prinzmetal's angina. The class of medication would reduce the incidence of coronary artery spasm. A beta-adrenergic blocker, such as metoprolol, is used to treat angina by decreasing myocardial oxygen needs, and has no effect on coronary artery spasms. An ACE inhibitor, such as enalapril, is used to manage hypertension. An inotropic vasodilator, such as milrinone, is indicated for short-term IV therapy in heart failure.
