positive feedback could be contractions(as painful as it may seem, its true) in child birth and the ripening of fruit.
negative feedback include the regulation of blood glucose levels and osmoregulation
Regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.
- Stem cells are specific cells capable of generating new specialized types of cells, thereby allowing the regeneration of damaged tissues.
- For example, hematopoietic stem cells can be used to generate new red blood cells whose function is to transport oxygen in the bloodstream.
- Regenerative cells can be used in tissue engineering in order to restore the function and structure of damaged organs.
In conclusion, regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

The more polar A compound moves ahead of the less polar B compound.
Explanation:
The analytical process that involves the separation of colored substance or chemicals is named as paper chromatography, a replacement of thin-layer chromatography. In this method, there is the use of two solvents and rotation of paper at 
. It helps in isolating two complex compounds of equal polarity.
A non-polar mixture of solvent is required in the mobile phase of this method. In accordance with the retention factor of this process, the more polar compound A will go further than compound B as the solvent is non-polar.
You sound unsure of yourself and you list negatives (not super negative but they’re not great) attributes about yourself. try listing more positive things about yourself besides you being “bored”, “annoying”, or “lazy”. Maybe you have a hobby like drawing or playing games, add things like that
