The phrase "activity species" is not a standard expression in written English and may cause confusion.
It could potentially be used in a specific scientific or technical context where "activity" and "species" are relevant terms, but clarity is essential.
Example: "In our study, we focused on the activity species of the enzyme to determine its effectiveness."
Alternatives: "active form" or "functional species".
The reason was due to its relatively stronger redox ability and surface activity species.
Three biogeomorphic succession phases were identified and related to degrees of activity, species composition, and strength of interactions.
A study was conducted in Iowa, USA to investigate the influence of the vegetative diversity of field boarders on the activity, species richness, and community similarities of predatory beetles occurring in corn fields.
As part of a research effort to improve the quality of current chemotherapy of Pneumocystis carinii pneumonia, we report a structure-based design project to optimise activity, species selectivity and pharmaceutical properties of the triazenyl-pyrimethamine TAB (4) (IC50=0.17 μM; rat liver DHFR IC50/P. carinii DHFR IC50=114).
And it's not just the number of bees that is dwindling rapidly - as a direct result of human activity, species are becoming extinct at a rate 1,000 times greater than the natural average.
Likewise, for biological activity, species were scored for the presence or absence of AChE inhibition or SERT binding activity.
The model of quantitative structure-activity-species relationships (QSASR) for the system of alcohols and animals chosen is proposed: log BAij = kj + lj log Xi log BAij = aj + bi log Zj where i denotes an alcohol, j an animal, BA being LD50 (mmole/m2) after IP application, X molecular connectivity 1 chi and Z body surface: body weight ratio.
To demonstrate the generality of the mutation-avoidance activity in species encoding NucS, the nucS gene was deleted in Streptomyces coelicolor A3(2), a different actinobacterial species.
I talked to Theodore Garland, a biologist at the University of California, Riverside, who has studied variations in voluntary physical activity between species.
The UQ research shifts conservation thinking which has historically targeted funding towards really threatened areas where there is a lot of human activity harming species.
All tree squirrels are diurnal and arboreal, but the range of vertical activity in species differs widely, especially among those living in tropical rainforests.
