What is needed most for photosynthesis?
Sunlight
100
The division of a cell into two daughter cells with the same genetic material?
Cell division

What are the levels of organization on earth from the lowest to the highest?
Atom, molecule, cell, tissue, organ, organ system,organism, population, community, ecosystem, and biosphere
200
In eukaryotic cells,what are the two main stages of cell division?
Meiosis and cytoplasm
200
What is photosynthesis?
A process what plants and other organisms use sunlight to synthesize food from carbon dioxide and water
200
The resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis?
Interphase

What would happen to the cellular respiration process if the enzymes for one step of the process were missing or defective?
The whole process beyond that point could not happen

What are biotic and abiotic factors?
Biotic factors have all living things in a ecosystem. Abiotic factors have non living parts of a ecosystem.
