Seasonal behavior in plants and animals is stimulated by?
Seasonal behavior in plants and animals is primarily stimulated by changes in day length and temperature. These environmental cues trigger physiological processes that help organisms anticipate and adapt to seasonal changes, such as changes in food availability, mating opportunities, or temperature fluctuations. Hormones like melatonin and phytochromes play key roles in regulating these seasonal responses.
What membrane proteins is responsible for binding hormones that can trigger changes in the cells activity?
The membrane proteins responsible for binding hormones and triggering changes in cell activity are called hormone receptors. These receptors are typically located on the cell membrane and can be categorized into different types based on their structure and mechanism of action. Upon hormone binding, these receptors initiate signal transduction pathways that lead to specific cellular responses.
Can you get headaches when the weather suddenly changes?
Yes, some people are sensitive to changes in weather and may experience headaches or migraines as a result. Rapid changes in temperature, humidity, or barometric pressure can trigger these headaches in susceptible individuals. It is thought that these weather-related headaches are due to changes in the brain's blood vessels or levels of certain chemicals.
What is ragweed used for?
Ragweed is not typically used for any specific purpose due to its strong allergic potential. Ragweed pollen is a common trigger for hay fever and seasonal allergies in humans.
An increase in the bloods level of a thyroid gland hormone decreases the release of thyroid-stimulating hormone this mechanism illustrates what?
This mechanism illustrates a negative feedback loop. When the blood levels of thyroid gland hormone increase, it signals to reduce the release of thyroid-stimulating hormone, which in turn limits the production of more thyroid hormone, helping maintain balance in the body.

Which hormone initiate the develompment of cell in ovarie and trigger testosteron to produce in the teste?
LH - leutenizing hormone.
Why are do some brown pelicans have white heads?
Some brown pelicans have white heads due to seasonal changes and breeding plumage. During the breeding season, adult males develop bright white head feathers, which are thought to attract mates. This coloration is a result of hormonal changes that trigger the molting process. Outside of the breeding season, their heads typically return to a darker brown color.
Does bananas cause headaches if your pregnant?
Bananas can be a Migraine trigger in many people. Migraines can become frequent during pregnancy due to hormone changes. See your doctor for appropriate diagnosis and treatment.
A drop in blood volume would trigger the body to secrete what?
antidiuretic hormone
Which plant hormones causes fruit to ripen?
Ethylene is the plant hormone responsible for fruit ripening. It is a gaseous hormone that acts as a signal to trigger the ripening process in fruits, leading to changes in color, texture, and flavor. Ethylene is commonly used in the food industry to ripen fruits artificially.
What is a mechanism by which a single hormone molecule can trigger the production of millions of molecules of a metabolic product?
enzyme
Does the equinox cause migraine headaches?
No. Migraine is a genetic, neurologic disease. The cause is usually genetic. Migraine may be triggered by things that can cause a change in the homeostasis of the body/brain however. The equinox is not generally considered to be a migraine trigger, although migraines may be triggered by seasonal changes and weather changes.
How can you get your tench to spawn?
Tench do not reproduce easily in aquariums. They rely on seasonal water changes to trigger spawning. The water has to be between 18 and 20 degrees C. Changing water temperatures and lighting conditions to match those occurring naturally may trigger spawning, but consistency with the seasons is a must. Even then, there is no guarantee the fish will fall for this artificial setup.

What is a memory trigger?
It could be a picture, word, symbol or sentence. It's something that triggers a memory or thought, hence the name 'memory trigger'
