What is the best explanation for the continual changes in the classification system of organisms?
All organisms struggle for existence and become extinct.
All organisms compete to be at the top of the food chain.
Technological advances like DNA sequencing have allowed scientists to better compare organisms.

What is the most accurate way to determine the classification of an organism?
Compare DNA sequences
Examine what the organism eats
Compare fur patterns
Examine migration trends
Because energy flows from organism to organism and is used for metabolism or is converted to heat the next organism in the chain only receives 10% of the energy from the previous level. Therefore, energy ___________.
increases as it flows through an ecosystem
decreases as it flows through an ecosystem
never changes as it flows through an ecosystem
causes explosions as it flows through an ecosystem

Mitosis is useful for the creation of new cells which is important for all of the following EXCEPT

Which of these correctly distinguishes mitosis from meiosis?(DOK3)
Mitosis occurs in sex cells and meiosis occurs in somatic cells.
Crossing over takes place in mitosis and not in meiosis.
