Answer:
Cytosine
Explanation:
Purine, Adenine, and Guanine are all purines
Prokaryotes are single-celled organisms with no nucleus, and so this would make bacteria a prime example. Therefore, depending upon the system being used, the kingdom that contains single-celled prokaryotes could be Monera, or the combination of Archaeobacteria and Eubacteria.
The kingdom systems, which were previously taught in high school, consisted of a 5-kingdom system which was later expanded to 6. The 5- kingdom included Animals, Plants, Fungi, Monera and Protists. The 6- kindgom system expanded Monera into Archaeobacteria and Eubacteria.
The "kingdom" system of classification is now generally not recognized as a valid or helpful way of classification, at least not according to modern evidence. It tends to be "paraphyletic", meaning that it describes relationships which do not match the evolutionary relationships of the organisms being described, and tends to favor human conventions rather than biological evidence. Kingdoms have generally been replaced by "domains" in terms of organizing relationships between organisms, referring to the prokaryotes, eukaryotes, and archaea, based on genetic and protein data.
Answer:
disruptive selection
Explanation:
Disruptive selection is the natural selection that favors two extreme phenotypes but does not favor the intermediate phenotype. Here, the survival and reproductive success of two extreme phenotypes are higher than that of the intermediate phenotype due to their higher fitness value in the prevailing conditions. The presence of deeper voices in males and less deep voices in females due to high and low levels of testosterone respectively represents the disruptive selection as the phenotype present at two extreme ends are favored.
