The right answer is false.
Angioplasty is a technique that can reopen narrowed or obstructed arteries in the heart (coronary arteries) without extensive surgery. First performed in 1977, angioplasty is now as common as coronary artery bypass graft surgery.
The treatment of arteriosclerosis is surgical or endovascular if there is a risk of life, significant functional impairment or major risk involving the life of an organ or limb.
Angioplasty is not the only surgery for this, Several surgical techniques aim at restoring the arterial lumen or irrigating the private territory or at suppressing the arterial aneurysm.
- Endoluminal angioplasty or dilation using a balloon with or without a stent to correct a stenosis or to recanalize a short arterial occlusion.
- The removal by endarterectomy which consists of removing the atheroma plug which obstructs an artery leaving only the weed.
- Bridging, which will "short circuit" the obliterated artery by allowing the passage of blood from the healthy artery upstream to the permeable artery downstream, made with venous, arterial or prosthetic material.
In case of an aneurysm two techniques are available: either bypass surgery in conventional surgery removing the aneurysm - or the stent covered excluding the aneurysm.
In all cases the risks must be compared to the benefits of each technique and correctly exposed beforehand. Each act must be adapted to each case according to the functional stage, the general state of the patient and his physiological age more than legal.
From what I remember it's called a substrate
Answer:
After constructing a prototype of the device, the student concludes that in many regions the monetary cost of building and installing the device would be higher than the cost of acquiring water from other sources. Which of the following would be most appropriate for the student to do next?
redesign the device without the solar panel so that it plugs into an electrical outlet
Explanation:
Because of cost implication, the device is redesigned in order to use other source rather than water which would be cost-effective and generally accepted for use.
the answer is the trophic level
