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.
Phat1 = 9/142
Phat 2 = 5/268
Phat 3 14/410
Test statistics = (Phat 1 - Phat 2) / (Square root of (phat × (1- phat))
times the square root of (1/n1 + 1/n2))
Test statistics = 2.373
P- value = 2× (1- normal cdf (2.373, 0, 1))
= 0.0176
At the level of significance, there is difference between the proportion of drug-resistant wihtin the two states.
Answer:
is a state of matter from a lower concentration to a higher concentration
In short, it was caused by 3,000 consecutive strong earthquakes. and caused by the freezing of lava causing glass particles.
Red clouds were seen at the volcano. The eruption was the result of intense seismic activity and a high rate of characterization in the weeks prior to the eruption. coupled with magma, which fuels the volcano
The second eruption occurred beneath the ice of a glacier. The cold water caused by the melting of the ice quickly cooled the lava and shattered the frozen lava into glass. This produces tiny glass particles which are carried in the ash spout. which that event As a result, airlines that leave Europe and enter Europe have to shut down for several days. coupled with the size of the eruption This is estimated to be 10-20 times the size of the eruption at Fimverduhaus. This resulted in a high-level atmospheric high-level of glass-contaminated ash plumes. which is dangerous for aircraft
