Positive affect" refers to one’s propensity to experience positive emotions and interact with others and with life’s challenges in a positive way. Conversely, "negative affect" involves experiencing the world in a more negative way, feeling negative emotions and more negativity in relationships and surroundings.
These two states are independent of one another, though related; someone can be high in positive and negative affect, high in just one, or low in both. Both states affect our lives in many ways, particularly when it comes to stress and how we handle it.
Answer:
stimulate blood vessels to develop within cartilage
Explanation:
Most connective tissue, cartilage includes have a very inadequate blood supply because it has no blood vessels innervations in it. It relies on diffusion for nutrient supply of the chondrocytes cells. This is why the chondrocytes divide very slowly compared to other cells. This is exactly the same reason why healing of cartilage takes more time to heal. In addition, due to the chondrocytes fixed position in lacunae, they cannot migrate to a scar to begin the healing process. Cartilages attempt to repair themselves usually by fibrocartilage scar tissue that is not ideal for restoration of movement at a joint.
