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
Answer:
d is correct am pretty sure
Explanation:
hope it helps
Explanation:
a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>
b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>
c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>

The main<u> </u><u>difference</u><u> between a</u><u> TIA</u> (transient ischemic attack) <u>and </u><u>RIND</u> (Reversible ischemic neurologic deficit) is the time duration taken for reversal of symptoms.
Explanation:
The symptoms of TIA can last for about 24 hours and settle within a day. RIND lasts for more than 24 hours and clears within a week or few weeks. This means that RIND is actually a mini version of TIA.
<u>Perspective of the paramedic:</u>
Since both the conditions exhibits acute mini stroke-like conditions with reversal of symptoms, the perspective of the paramedic will be the same for both TIA and RIND.
The paramedics in the field should conduct GCS and FAST tests, detect stroke and its damage caused, should obtain other basic information at the field, and administer basic neuroprotective treatment modalities to save the patient from further damage.
<u>In the hospital,</u> for both TIA and RIND, the primary stroke management is to restore the blood supply to the brain through anticlotting agents like tPA injections or endovascular procedures
. The treatment can vary later according to the severity of the stroke.
