MOST microorganisms show optimal growth at low osmotic pressures, but even so are often able to grow, though more slowly, in the presence of concentrations of environmental solutes sufficiently high ...

This resource guides a-level biologists through the role of each part of the nephron in osmoregulation. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource ...

Specimens of Oscar Astronotus ocellatus from a fish farm were abruptly submitted to salt stress of 14 ppt and 20 ppt, for 3 and 8 h to determine their plasma osmolality. Muscle wet body mass change in ...

Prolactin is an important regulator of multiple biological functions in vertebrates, and has been viewed as essential to ion uptake as well as reduction in ion and water permeability of osmoregulatory ...

This resource guides a-level biologists through the role hormones play in osmoregulation. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be ...

When you imagine a patient in a hospital bed you will probably picture an intravenous (IV) drip as part of the scene. Between 80% and 90% of hospital inpatients will receive an infusion of one or more ...

When red blood cells break down, they release heme, a component of hemoglobin that can contribute to inflammation and damage tissues and blood vessels. Researchers at Lund University have identified a ...
