What is organizer and inducer substance?
An organizer substance is a molecule or structure that regulates development by influencing the pattern of cell differentiation. An inducer substance is a molecule that promotes a specific developmental process by initiating cellular responses in surrounding cells. Both are important in controlling the growth and differentiation of cells during development.
During the alarm stage what substance does the body release the triggers response to a threat?
During the alarm stage of the stress response, the body releases hormones like adrenaline and cortisol to prepare the body for the "fight or flight" response to a threat. These hormones increase heart rate, blood pressure, and alertness to mobilize resources for a quick response to the danger perceived.
During contraction of the heart muscle cells?
some calcium enters the cell from the extracellular space and triggers the release of larger amounts of calcium from intracellular stores
What is the process in which a physiological change triggers further change in the same direction?
Positive feedback loop is the process in which a physiological change triggers further change in the same direction. The initial change leads to more of the same change, amplifying the response. An example is the release of oxytocin during childbirth, which stimulates contractions leading to more oxytocin release.
Does engaging in sexual activity trigger the release of dopamine in the brain?
Yes, engaging in sexual activity triggers the release of dopamine in the brain. Dopamine is a neurotransmitter associated with pleasure and reward, and its release can contribute to feelings of pleasure and satisfaction during sexual activity.

Is Oxytocin release a positive or negative feedback control mechanism?
Oxytocin release is a positive feedback control mechanism. This means that an initial stimulus triggers the release of oxytocin, which then promotes further release of oxytocin, amplifying the response until a specific outcome is achieved, such as uterine contractions during childbirth.
