Answer:
The answer is E. Sodium, potassium, and chloride ions but not water.
Explanation:
The thick segment of the ascending limb of the nephron loop is permeable to: sodium, potassium and chloride ions, but not water.
In this ascending branch are specific ionic channels for each of them. This ascending area of the henle handle is continued with the distal contoured tube where reabsorption and ion secretion occur again to further converate the urine.
Answer:
Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%
Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
To obtain a scan using the positron emission tomography technique, a patient is injected with (or ingests) a low and harmless dose of a short-lived radioactive glucose.
<h3>
What is Positron emission tomography?</h3>
This refers to a type of imaging technique which employs the use of radioactive substances in other to measure the metabolic activity of the cells of body tissues.
A scan using this technique is obtained by injecting the patient with a low and harmless dose of a short-lived radioactive glucose so that a picture of where the glucose being used in the body is visible and helps to detect cancerous cells etc.
