These medicines are called antisecretory because they work by blocking the acid secretion of the stomach.
This is the case of the H2 antihistamine (such as Cimetidine) which has a rapid action (approximately 1 hour) but longer than an antacid.
When symptoms are frequent, occurring more than once a week, proton pump inhibitors (PPIs) (such as Omeprazole), antisecretory agents of potent and prolonged action (at least 24 hours), constitute the treatment of choice.

Answer:
True. It is because pollution is caused from greenhouse gases such as carbon dioxide, which eventually affects the environment and atmosphere by raising the temperature (global warming) which is caused by the greenhouse effect.
Answer:
(C) Only BamHI and BglII fragments are compatible.
Explanation:
First we can visualize how the enzymes cut by completing the strand below and cutting where indicated. The three enzymes cut with cohesive ends.
Then we can complete the sense of the strands and serach compatible ends. Keep in mind that we can only join 5 'ends with 3' ends.
BamHI = G...3' 5'...GATCC
CCTAG...5' 3'...G
XbaI = T...3' 5'...CTAGA
AGATC...5' 3'...T
BglII = A...3' 5'...GATCT
TCTAG...5' 3'...A
In bold, leave the bases that remain in single strand and must be compatible with those of the other end.
To be compatible they must be complementary bases. A with T and C with G.
Now you can see that only BamHI fragments are compatible with those of BglII.
