When people experience indigestion, hey often take an antacid to soothe their stomachs. do you think taking an antacid is effective? explain your answer

When someone is experiencing indigestion and take an antacid, the antacid is effective. The reason why they are effective is because of one of three types that are OTC, currently.

1. Proton pump inhibitors like Nexium, Protonix, Prilosec, etc...what proton pump inhibitors do is they block/inhibit the production of gastric juices by the stomach and are long lasting.

2. H2 receptor antagonists like Pepcid AC, Zantac. What these do is inhibits histamine reactions of acid secretions from the stomach.

3. Calcium carbonate. What this does is acts as a buffer of the gastric acid. It will attempt to neutralize how much acidity is in the gastric juices from an over production.

The stomach is an extremely acidic environment. Antacids temporarily neutralize the acid and soothe the stomach.

Explanation:

the answer to your question is b

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
