Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.

Answer:
Adaptive radiation
Explanation:
Adaptive radiation occurs when an ancestral species move to a new environment that has various resources that are necessary for survival and also has environmental conditions that would ensure its offspring adapt well over time. In this new environment, the ancestral species would produce offspring with different traits and behaviors that will allow them to survive in this new environment while occupying their various niches. Over a relatively short time, different species arising from the common ancestor would occupy the new environment.
The single-celled organism with a nucleus can be categorized into FUNGI OR PROTIST
- Living organisms has been classified into six kingdoms namely: Animalia, Plantae, Fungi, Protista, Monera and Archaebacteria.
- Among these kingdoms, kingdoms Animalia, Plantae, Fungi, and Protista are all EUKARYOTIC. This means that they possess a true nucleus in their cells.
- However, characteristically, among the eukaryotic kingdoms we have, only kingdoms FUNGI and PROTISA contain members that are single-celled.
Hence, a single-celled organism with a nucleus can be categorized into FUNGI OR PROTIST
