С
Their effects increase as the population increases in an area.
The correct option is B.
What are density Dependant and independent factors?
Density-dependent factors regulate the growth of a population depending on its density while density-independent factors regulate population growth without depending on its density.
What are 4 density-independent factors?
While the previously mentioned density-dependent factors are often biotic, density-independent factors are often abiotic. These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons.

The fossil record shows that the average size of black bears was large during cold glacial periods and got smaller during warmer time periods
is an example of Directional selection.
What is a directional selection?It occurs when individuals with traits on one side of the mean in their population survive better or reproduce more than those on the other.
What does directional selection do?It is compelling in nature that causes a population to evolve towards one end of a trait spectrum.

Which stage of mitosis is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids?
Answer: Anaphase.
Explanation:
The stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.
Mitosis is a type of cell division by which a parental cell divides in order to produce two genetically identical daughter cells.Mitosis has four phases prophase, metaphase, anaphase, and telophase.During prophase, chromatin condenses into chromosomes, the nuclear envelope disintegrates and spindle microtubules grow and extend from each pole of the cell.During metaphase, homologous chromosomes line up at the equator plate of the cell, the mitotic spindle is fully developed and it attaches to the kinetochores that appear at the centromeres.During anaphase, chromosomes are separated by the elongation of the mitotic spindle and pulled to opposite poles of the cell.In conclusion, the stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.
