The founder effect is the loss of genetic variety that happens when a new population is founded by a small number of individuals from a larger population, according to population genetics. Ernst Mayr was the first to thoroughly explain it in 1942, based on previous theoretical work by people like Sewall Wright.

Answer:
C. Exocytosis uses transport vesicles to export materials from the cell
Explanation:
Exocytosis is the reverse process of endocytosis including the expulsion of the material that is membrane -encapsulated (material is packaged in the vesicles ) inside the cell out of the cell. It has following steps :
1) The cell forms a vesicle around a material which is to be expelled.
2) The vesicle is transported to the cell membrane.
3) The vesicle membrane fuses with the cell membrane and releases the contents from the cell.
Hence option C. Exocytosis uses transport vesicles to export materials from the cell IS THE RIGHT OPTION.
The cell nucleus acts like the brain of the cell. It helps control eating, movement, and reproduction. It contains the genetic material and controls the function of the cell.
Answer:
During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.
