Answer:
See explanation and image attached
Explanation:
The structure of imidazole is attached to this answer. The compound is colourless. The solid can be to dissolved in water leading an alkaline solution. Owing to the fact that imidazole possesses heteroatoms in an aromatic heterocycle it is classified as a diazole. The nitrogen atoms in imidazole are not adjacent to each other.
From the structure shown, we can see that the lone pair of the sp2 hybridized nitrogen atom is available because it is not part of the aromatic system of the heterocycle. This nitrogen is much more basic than the nitrogen atom attached to hydrogen whose lone pair becomes part of the aromatic sextet hence it unavailable for protonation and less basic.
Answer:
The correct answer is a) all of these
Explanation:
Human body developed many mechanisms to regulate the pH of the body fluid. Carbon dioxide in the blood forms carbonic acid which neutralize the extra base and decrease the pH of blood.
Bicarbonate ions in the blood helps in neutralizing the extra acid in the blood and is reabsorbed by kidneys. Excretion of excess H⁺ ions from kidney also helps in regulating the pH of body fluid.
Almost all the proteins acts as buffer because they have charged regions which can bind to H⁺ or OH⁻ ions thus provide buffering capacity to the blood.
Thus, the correct answer is a all of these.
Answer:
The aim is SPECIMEN
Explanation:
The aim is to obtain a sample (specimen) of urine from the middle of your bladder. Urine does not normally have any germs (bacteria) in it (urine should be sterile). ... A midstream specimen of urine (MUS) is best, as the first bit of urine that you pass may be contaminated with bacteria from the skin
Answer:
The correct option is : b. Hydrochlorothiazide
Explanation:
Postural hypotension, also known as the orthostatic hypotension, is a medical condition in which the blood pressure of a person drops while in a standing or sitting position. This condition is characterized by a drop in the systolic and diastolic blood pressure of at least 20 and 10 mm Hg respectively. This drop in blood pressure can be sudden or gradual.
The hydrochlorothiazide is an anti-hypertensive drug which can cause postural hypotension.
Mitral regurgitation is a leakage of blood that flows backward via the mitral valve during contraction of the left ventricle which results in systolic murmur.
<u>Explanation:</u>
Mitral valve is seen between the left atrium and left ventricle,it prevents the back flow of blood during left ventricular contraction. In case of mitral valve regurgitation or stenosis condition it results in back flow of blood to left atrium it further results in increased blood pressure in left atrium and fluid buildup in lungs and leads to systolic murmur. During cardiac cycle systole occurs when heart contracts and diastole occurs when heart relaxes.
