The phrase "a different level of activity" is correct and usable in written English.
It can be used to describe varying intensities or types of engagement in a particular context, such as work, exercise, or social interactions.
Example: "The new program encourages participants to engage in a different level of activity compared to previous sessions."
Alternatives: "a new degree of engagement" or "an alternative intensity of involvement."
In another experiment, participants were shown a series of MRI images, each showing a different level of activity in the brain, and asked to identify which they thought corresponded with their own brain while they answered a series of self-assessment questions.
Separation of the compound isomers is in progress to determine whether the R- and S-forms show a different level of activity toward tubulin in vitro and in cells.
Differential network analysis revealed several genes which showed a different level of activity in the pathways they represented.
Similarly, it is likely that a different level of activity is present in the upper extremities of SCI individuals after the lesion.
These researchers found that lysates from cancer tumors often had a different level of activity and a different stereoselectivity towards several chiral esters than the corresponding normal tissues.
For example, the lack of correlation between dosage compensation and high flux control demonstrates that the threshold lies at a different level of activity for each gene or protein.
To test this model Despina, together with Fausto Ulloa, made a series of dominant active Gli constructs each producing a different level of transcriptional activity.
Due to the variation in the synthesis step, the products may exhibit a different level of antibacterial activity.
Furthermore, the combination between choline kinase isoforms results in a different level of ChoK activity in vitro under cell-free systems conditions.
In vitro studies have demonstrated that these clones have a different level of enzyme activity known to play a role in virulence [ 14, 15].
When the team then bred lab mice with just one copy of PrKar1a, which has also been implicated in male fertility in humans, male mice had sperm with shorter midpieces, leading the researchers to conclude that competition among deer mice sperm has driven that species to have a different level of PrKar1a gene activity, and consequently faster, more competitive sperm.
