Answer: Many left-handed people report being able to use their right hand very well for a certain burden(task), because of needing to adapt to tools which are usually designed for right-handed people like scissors, golf clubs, and some people are also mix-handed, where they perform some tasks with one hand and other tasks with the opposite hand. Some people have true ambidexterity where they can perform burden(task) equally well with both hands. Learning Point is were children begin to develop hand dominance around about 2 to 3 years and this should be well developed by the age of 5 and fully developed by the age of 6. Use of a dominant hand before 2-3 years time may occur because of abnormal fine motor development. It could also be the result of an intracranial injury or an injury to a limb with appropriate compensation by the other limb. The development of hand dominance after the age of 6 years, again may indicate abnormal development.

Hey There,
The best way to prevent heat exhaustion while exercising is
D) Avoid exercise in extreme heat or humidity
While working out in the summer in a non-air conditioned place isn unhealthy and not safe. Doing this can lead to a stroke or heart attack. If it is already hot and you are adding on heat, that overwhelms the body. This action should not be done while exercising. Make sure you have a cool temperature building and are drinking lots of water.
Best Of Luck,

Healthy-eating, I think is the right answer
It should be associated with recovering an healthy weight, physical exercise, no more smoking and no stressful environment
hope it helps !
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.
