Quantitative hCG results measure the level of human chorionic gonadotropin in the blood. The results are typically reported in mIU/mL (milli-international units per milliliter) and are used to track the progression of pregnancy or assess for complications. Higher hCG levels generally indicate a healthy pregnancy, while lower levels may suggest a potential issue with the pregnancy.
Predator-prey relationships can regulate population sizes by keeping prey populations from growing unchecked. Predators hunt and feed on prey, reducing their numbers. As prey populations decrease, predator numbers may also decline due to reduced food availability, which in turn can allow prey populations to recover. This cycle helps maintain a balance between predator and prey populations.
Social mobility is the ability of individuals or families to move up or down in the social class hierarchy.
