What is the difference between Mitosis and Meiosis?
(Potential but not the only acceptable answers)
Mitosis results in 2 diploid cells, Meiosis makes 4 haploid cells
Meiosis has crossing over and 2x PMAT
100
Difference between a biotic and an abiotic factor?
Biotic is living things, abiotic is nonliving that affects the function of ecosystems.

What was the island with the finches called?
The Galapagos Islands
100
What is the powerhouse of the cell?
Mitochondria
200
Why do finches on the Galapagos island have different beaks?
Response should be something like: Competition/natural selection results in favorable traits, causing different species of finches with beaks best suited for survival in their environment.
