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.
Answer: Ii. Eukaryotic dna has Telomeres.
Explanation:
Deoxyribonucleic acid is a substance that has double helix coil and contain the genetic material . DNA differ in prokaryotic and eukaryotic cell. Prokaryotic cells have no membrane bound nucleus while eukaryotic cells have membrane bound nucleus.
Prokaryotes DNA is found in the cytoplasm and the eukaryotes DNA is found in the nucleus.
Prokaryotes DNA lacks telomere while eukaryotic DNA have Telomeres. Telomeres is a specialized dna cap that consist of hundred or thousands of DNA repeats. It prevent loss of Gene.
Antibodies are white blood cells that destroy antigens. Antitoxins are white blood cells that destroy toxins(poisons).
Answer:
B. Allopatric speciation; vicariance.
Explanation:
Allopatric speciation is a model about the evolutionary process of the species around the world. The characteristic of this model is that it talks about populations of the same species that become isolated one from each other like in the example of the question given.
Both turtles have the same ancestor but as one is on an island it evolves differently from the turtle that remains on the continent. Nevertheless, as the turtle from the island was isolated from the other on the continent they both evolve differently with almost the same DNA.
