Four pairs of monozygotic twins, who were separated tested for their ability to solve geometry problems. The highest score obtained was 96 points, while the lowest was 6 points. If the scores between each twins were similar, and the scores obtained by different twins were more variable. How do you think about the trait of one's ability to solve geometry problems? determined mostly by genetic factors It is random not related to genetic or environmental factors depends solely on the environment O it cannot be interpreted based on results of twins separated after birth

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
