Answer: B) Population size is the total number of organisms, while population density is the total number of organisms within a given area.
Population size refers to the total number of organisms present in a population. On the other hand, population density reflects population size per unit area.
For example- In a population, if 200 individuals are living in 100 square meter of area.
Population size = 200
Population density = 200/ 100 = 2 individuals per square meter.
Answer:
2. Parathyroid hormone level decreases
4. Ca and phosphate reabsorption decreases
Explanation:
When plasma Ca concentration decreases, the action of Parathyroid hormone level decreases which leads to Calcium and phosphate reabsorption decreases. Parathyroid hormone is responsible for the increase of calcium and phosphorus in the blood when there is low level in the blood so when the re is huge amount of calcium and phosphorus in the blood, the Parathyroid hormone activity decreases which decrease the reabsorption of calcium and phosphorus decreases.

All life as we know it is carbon-based, so what scientists could determine is that there is no carbon-based life at the origin of the meteorite. However, this does not necessarily mean that there is no life there; our knowledge is only based on our experiences of life on Earth, so it is possible that life has developed in other regions of space upon other elements and formations. For example, there could be life based on silicon or other chemical compositions.
