Answer:
Given
Per Kg of body mass, there is 3 gram of potassium
And abundance of three isotopes are as follows
Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.
1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram
= 240*0.012/100 = 0.0288 gram.
2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg
Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10
The answer would be a Doctorate in veterinary medicine.
The pathophysiology of dementia of the Alzheimer type is loss of volume of brain tissue as neurons deteriorate and die.
<h3>What is Alzheimer disease?</h3>
Alzheimer disease is a type of disease that affects the brain cells and it's otherwise called a neurosis.
It is a neurodegenerative disease that is characterized by dementia, that is initial memory impairment and cognitive decline.
Pathophysiology of a disease is the pathway that shows how the disease affects the physiology of the body systems.
The pathophysiology of Alzheimer's disease include:
- The beta-amyloid deposition and neurofibrillary tangles lead to loss of synapses and neurons,
- This results in gross atrophy of the affected areas of the brain leading to death of brain cells.
Therefore, the pathophysiology of dementia of the Alzheimer type occurs due to beta-amyloid deposition which leads to loss of volume of brain tissue.

Answer:
The correct answer will be option B-left atrium.
Explanation:
The coronary circulation is the circulation of blood and nutrients to the myocardium of the heart on both sides.
The coronary system consists of coronary arteries and coronary sinus(vein) in which coronary arteries arise from the main artery of the circulatory system called aorta. This aorta arises from the left atrium of the heart which supplies oxygenated blood. These coronary arteries divide into left and right arteries which supply oxygenated blood to the heart.
Thus, option B-left atrium is the correct answer.
