Answer:
H. pylori uses the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2), where NH3 can act as a buffer to the acidic solution in the stomach.
Explanation:
<em>H. pylori</em> is a bacteria that has the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2). The compound of interest here would be ammonia, or NH3. NH3 is a base, although relatively weak to other stronger bases, which means it has a pH above 7. In the stomach, the pH is acidic, or below 7. By synthesizing ammonia, <em>H. pylori </em>is able to buffer the stomach solution in a manner so that it isn't entirely acidic, but more toward the basic side, thereby allowing for its survival.

Malleability is the ability of metals to be hammered into sheets.
Metals are often required for different applications. The ability of metals to be hammered into sheets is called malleability.
Malleability of a metal is closely related to its density. The denser the metal, the less easily malleable it is.
Both copper and strontium are metals but copper is denser than strontium hence copper is less malleable than strontium.

A recent survey by nutritionist Roberta Cassani of the Institute of Nutrition in Itu, São Paulo state, shows that the greater the number of hours without putting anything in the mouth, does not help anyone lose weight, on the contrary, fasting causes the increase of the circumference of the abdomen.
According to the scientist, the main reason that prolonged fasting is an enemy of the waist is that the meal set up after this period of scarcity is usually an example of caloric and nutritional imbalance - in the research, fasting usually occurred in the afternoon. “When they have access to food, the greedy individual does not make healthy choices,” explains the expert. Being deprived of energy, the body triggers a whole mechanism that favors the binge eating, the result is that the individual gets fat.
