Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words,isotopes have the same atomic number because they are the sameelement but have a different atomic mass because they contain a different number of neutrons.
What is this supposed to mean
Answer;
High content of sodium.
A drawback to the use of the antacid drugs sodium bicarbonate, alka-seltzer, and baking soda is their high sodium content.
Explanation;
Antacid drugs are weak bases that exert a therapeutic effect by neutralizing hydrochloric acid, thus relieving indigestion, heartburn and hyperacidity. These antacids contain high levels of sodium which could make an individual unwell, especially those that have illness that needs them to control how much salt (sodium) they take in the diet.
Answer:
The correct answer will be option-B
Explanation:
Kidneys help maintain the blood volume by activating renin-angiotensin-aldosterone (RAAS) system. The activation of the system increase sodium retention which helps reduce the amount of water lost into the urine.
The RAAS system is activated when the receptors sense the decrease in the volume of the blood. This leads to the production of renin from the juxtaglomerular cells of the kideny. The renin help converts the inactive angiotensin to angiotensin I and angiotensin II by ACE enzyme.
Angiotensin II stimulates the production of aldosterone from the adrenal cortex which promotes the retention of sodium from tubules and maintains the long term blood pressure.
Thus, Option-B is the correct answer.
Activation of the renin-angiotensin-aldosterone (RAAS) system causes increased sodium retention by the kidneys, which leads to reduced water loss into the urine and therefore blood volume expansion. RAAS activation occurs during heart failure, which leads to fluid retention in the body. RAAS activation also occurs with renal artery stenosis, which is one cause of secondary hypertension.
