Answer:
The answer is "Mode of replication".
Explanation:
The answer is the model for reproduction because it is the genetic reproduction implements a diffraction model, which replaces some old bases with other small colonies for each strand of the fetus, opposed to a semiconservative model of reproduction in eukaryotic cells, wherein one chromosome is completely new and one is old.
The correct answer is "the keywords were not sufficiently narrowed".
In this example, the literature research yielded a great and unmanageable number of citations. It is practically impossible to read all these citations and most probably some of these citations are not relevant to what the nurse researcher is looking for. Therefore, this literature research needs to be conducted again, by narrowing down the focus using more precise terms.
The study of tree rings is called dendrochronology. Trees produce a single growth ring each year and by studying the size and composition of each ring scientists can get information about the age of the tree, available nutrients in the area, and general climatic conditions. A relatively small ring may indicate a year when there was very little rainfall and a larger ring indicates favourable conditions for plant growth.
Ice cores hold information on past global volcanic activity and past atmospheric conditions. Tiny bubbles in the ice cores give information on the concentration of gases in the atmosphere. Ice core data plays a key role in linking the increase in carbon dioxide concentrations to present day global warming.
