Answer:
Option D, Zinc is higher on the activity series because there is clear evidence of a reaction.
Explanation:
It is very clear that a metal which is higher in activity will replace a metal having lower activity.
Since, Zinc has higher activity than copper, it is very sure that it in a copper chloride solution it will replace copper and produce zinc chloride solution leaving behind copper as residue.
Residues of copper is a clear evidence of reaction
The chemical equation for this reaction would be -
Hence, option D is correct
The patient can be subjected to intraoperative cholangiography wherein a stent in the bile duct will be placed and a radiopaque dye will be injected. X-rays will be taken. This is to locate the level of obstruction and to confirm if there is a common bile duct obstruction. In extracting stones, the surgeon can prefer doing an endoscopic retrograde cholangiopancreatography or ERCP and perform basket extraction of the common bile duct stone; or to surgically remove the sphincter of Oddi to allow easy passage of the stones.
Answer:
Eukarya
Explanation:
According to the given information, the observed cells have nuclei and chloroplasts. The presence of a well-defined nucleus and other membrane-bound organelles such as chloroplasts is a feature of eukaryotic cells. All the eukaryotic organisms are assigned to the Domain Eukarya. Therefore, the observed cells belong to the domain Eukarya. Due to the presence of chloroplasts in them, these cells may belong to the kingdom Plantae of domain Eukarya. Domains Archaea and Bacteria include prokaryotic organisms.
