Sentence examples for by variable levels of from inspiring English sources
Even though IUP is usually considered in litter-bearing mammals where fetuses are influenced by variable levels of steroids (androgens and/or estrogens) due to the sex of neighboring fetuses, a similar situation can be found in dizygotic (DZ) twins indicating that humans are also sensitive to steroid influences by the neighboring embryo.
We note that determination of dephosphorylation kinetics in certain preparations of Maf1 was prevented by variable levels of a contaminating protease.
Despite being connected by variable levels of gene flow, these populations can indeed follow semi-independent adaptive evolutionary trajectories shaped by selection by their local environments.
