yes hormones can be secreted in response to external stimuli. the bast example is adrenal hormone. whenever you are afraid of some external causes it gets released
Plant growth hormones e.g. IAA.
Humoral stimuli cause endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients.
Oxytocin is produced in the hypothalamus and secreted by the pituitary gland in response to various stimuli, such as childbirth, breastfeeding, and emotional bonding.
The movements of plants in response to external stimuli are called tropisms. These include phototropism (response to light), gravitropism (response to gravity), and thigmotropism (response to touch).
Regulatory stimuli refer to external factors or signals that trigger a regulatory response in an organism, functioning to maintain homeostasis or control physiological processes. These stimuli can include changes in temperature, pH, or nutrient levels that prompt a specific biological response in order to maintain internal balance within the organism.
Yes many plant hormones are secreted by plants internally. Such as auxin, gibbrailin, cytokinin etc.
Plant growth hormones e.g. IAA.
sweat
Hormones.
i don;t know lol
Plant growth hormones e.g. IAA.
Humoral stimuli cause endocrine glands to secrete their hormones in direct response to changing blood levels of certain critical ions and nutrients.
Cells constantly change in response to external stimuli.
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.
Auxins response to external stimuli like water, sunlight, support(thread), gravity etc.
Vocalization of an expletive typically occurs in response to unfavorable external stimuli.
there are so many forms of hormones in the body, but ultimately the brain sends a signal for each one to be released. For puberty, the pituitary gland in the brain is the one that decides to release androgens or estrogens to start puberty
