The phrase "activity and concentrations of" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing the levels or amounts of substances or phenomena in a given environment.
Example: "The study measured the activity and concentrations of various pollutants in the water samples."
Alternatives: "levels and activities of" or "amounts and intensities of".
In the present case-control study, complement activity and concentrations of complement components and their activation products are measured in AMD patients and in unaffected controls and correlated with genetic variants in the CFH, ARMS2, C3, CFI, and CFB genes.
Stabilisation is degree of decomposition of a waste substance, which is reflected by decrease in level of microbial biomass activity and concentrations of labile compounds (Benito et al. 2003).
Specifically, the organic strawberries, while having lower concentrations of phosphorus and potassium, had higher antioxidant activity and concentrations of ascorbic acid and phenolic compounds, longer shelf life, greater dry matter, and, for 'Diamante', better taste and appearance.
Consequently, if we consider signaling only through the frequency of calcium oscillations, negative interactions and exposure to cAMP-generating ligands increases the robustness of signaling to fluctuations in the activity and concentrations of upstream components.
We found that the organic farms had strawberries with longer shelf life, greater dry matter, and higher antioxidant activity and concentrations of ascorbic acid and phenolic compounds, but lower concentrations of phosphorus and potassium.
Our results do not support the initially-published conclusion that AGE serum concentration correlates with RA activity and concentrations of inflammation markers.
The CAT activity and concentration of H2O2 during photocatalytic process were compared to further confirm the role of H2O2.
Organic matter, which makes up a significant percentage of aerosol mass in the troposphere, (the lowest layer of the Earth's atmosphere and the one in which we live) can profoundly influence the activity and concentration of CCN and cloud droplets.
A numerical example is used to examine the influence of the catalytic activity and concentration of the impurity on the desirable level of the poison in the reaction mixture.
This study compared the biological activity and concentration of PRO 2000 in cervicovaginal lavage (CVL) collected in the absence or following coitus.
Transgenic Leucaena leucocephala plants expressing antisense OMT displayed decreased activity of OMT activity and concentration of lignin [ 100].
