This mechanism has positive correlation between the products and the process. The positive feedback mechanism result in the growth of a product. This mechanism is less common in organism and perform under specific conditions. Example: Process of blood clotting involves positive feedback mechanism.
Negative feed back mechanism:
This mechanism has negative correlation between the products and the process. Negative feedback mechanism result in the inhibition of the product. This mechanism is more common in organism and maintains homeostasis in the body.Example: Regulation of blood pressure involves negative feedback mechanism.
Positive and negative feedback mechanisms are means by which Earth’s systems interact. Positive feedback involves an increase in the first variable leading to an increase in subsequent variables that ultimately leads to a greater increase in the first variable. Negative feedback involves an increase in the first variable, leading to an increase in subsequent variables that ultimately leads to a decrease in the first variable. Positive feedback speeds up the process and leads to instability. Negative feedback reduces changes in the system and helps to stabilize it.
The difference between a dominant trait and a recessive trait is that the dominant trait must have one copy of each from two different parent Example: Brown Hair=H Light hair=h Hh is dominant because this is of a copy of each from two parents A recessive trait must have two same copies coming from the same two parents Example: HH
<span>Biology is a very important thing in life it helps us understand what all other living creatures live and what they do to survive and that will lead us to ideas to help us understand about living creatures.</span>
