The stimuli causing endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients are called __________
The stimuli causing endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients are called Humoral stimuli.
Humoral stimuli refer to the control of hormone release in response to changes in extracellular fluids such as blood or the ion concentration in the blood. For example, a rise in blood glucose levels triggers the pancreatic release of insulin.
The term humoral is derived from the term humor, which refers to bodily fluids such as blood. Insulin causes blood glucose levels to drop, which signals the pancreas to stop producing insulin in a negative feedback loop.

What is the tolerance range of a species?
The tolerance range can be defined as the range of environmental conditions between which an organism or a species is potentially capable of surviving.
When talking about environmental conditions, we are referring to factors such as temperature, pH, latitude, altitude, salinity, humidity, radiation, etcetera. These are the limiting factors.
Limiting factors are environmental biotic or abiotic conditions that directly act on populations and individuals, limiting their distribution and growth. These factors affect natality and mortality rate, migration, etcetera.
The tolerance range depends on the species and the individual development stage.
• Different species express different tolerance ranges for the same limiting factor.
• An individual can change its tolerance range with time.
Three different zones can be distinguished for a species according to its tolerance range,
Optimum zone → there is a high number of individualsPhysiological stress zone → there is a low number of individualsIntolerance zone → No individuals at allIn the exposed example,
