The phrase "arise singly" is correct and usable in written English.
It can be used to describe situations where something occurs or emerges individually rather than collectively.
Example: "In the study, the researchers noted that the issues tended to arise singly rather than in clusters."
Alternatives: "occur individually" or "emerge separately".
The sac fungi are separated into subgroups based on whether asci arise singly or are borne in one of several types of fruiting structures, or ascocarps, and on the method of discharge of the ascospores.
Phialides L/W 8.8 9.2 × 4.0 4.2 μm, arise singly, directly from any of the branches, or they arise in whorls at the end of branches, phialides often doliform then clustered in grape-like fashion, when not densely clustered they are ampulliform.
These data refute the possibility that oct-GnRH arose singly in cephalopods by convergent evolution and provide valuable support for an ancient origin of GnRH during metazoan evolution.
Some isolates produced AC in clusters, some in pairs (Figure 1C), and in other cases AC arose singly from hyphae (Figure 1A B).
Roots diarch, usually arising singly from one leaf trace, containing scattered sclerenchyma fibres.
Roots typically arising singly is a useful character discriminating Osmundastrum and Osmunda pulchella from the remaining Osmunda, although this feature is inconsistent and may be difficult to observe [ 11, 30].
Thus, the defect-related bands arise from singly and doubly charged oxygen vacancies and their intensities increase when the population of oxygen vacancies increases after increase Mn concentration in our Mn-doped ZnO NRs.
Fruit bodies may grow singly, in groups, or clustered together.
If high- and low-affinity interactions do arise from negative cooperativity, singly-occupied dimers should be most abundant at low concentrations of ligand, and doubly occupied dimers should only form at higher concentrations of ligand.
Dual resistance may also arise during combination therapy while singly-resistant cells are killed through treatment.
This is consistent with the model, which proposes that revertant colonies are initiated by singly mutant cells that arise during nonselective growth either prior to plating or during the period of tester growth during day 1 after plating.
