What's the difference between mitosis and meiosis?
Mitosis is the replication of body cells, wherein 1 cell produces 2 identical somatic cells. Meiosis, however, is needed for reproduction and 1 cell produces 4 genetically different daughter cells (gametes).
How does tone convey the speaker's attitude?
The tone of voice of a speaker can indicate how they feel about the subject at hand, as certain adjectives and phrases have a negative or positive indication when used in a sentence. For example, "He looked around the room, stretching tall at the sight of the crowd and smirking at their full attention," conveys a different tone than "She looked around the room, seeming to shrink into herself at the attention they gave her."
What test is needed to determine if there is a statistically significant difference between school year and long jump distance?
Since school year is a categorical variable and long jump distance is a continuous numerical variable, an independent t-test is needed.
