The correct answer to the question about why can a Benedict solution be used to distinguish between a glucose and a sucrose is letter A. Benedict's Solution is used to test the presence of reducing sugar. Glucose is a reducing sugar while Sucrose is a non-reducing sugar since it has a glycosidic bonds between their structure that hinders the formation of open chain. In the end, Sucrose stuck at its cyclic form.
Hi,
By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.
Option c) is the correct option above.
<span>c) Fossils give information about the time period in which organisms lived in the past.

Answer
A fish ladder can help fish migrate past barriers both natural and artificial (dams)
Explanation
A fish ladder is a structure constructed around natural barrier or artificial ones (dams and waterfalls) to facilitate fish migration in a natural manner. It is also called a fish way, fish pass or a fish step. With the help of such structures, fish protection and restoration is achieved thus boosting their numbers and maintaining a natural habitat.
