Explanation:

1. For "cell – smallest structural and functional unit of an ______", the word "organism" fits as cells are the units of organisms.
2. For "stimuli – a ______ to which an organism responds to", "signal" is appropriate as stimuli are signals.
3. For "response – a reaction to a ______", "stimulus" (singular of stimuli) fits as response is to a stimulus.
4. For "homeostasis – steady internal, physical, and chemical conditions ______ by living systems", "maintained" is correct as homeostasis is about maintaining conditions.
5. For "Growth – an ______ in mass and size", "increase" fits as growth is an increase.
6. For "Development – ______ that occur within an organisms’ life cycle", "changes" is correct as development involves changes.
7. For "Asexual reproduction – a ______ parent produces offspring genetically identical to itself", "single" fits as asexual has one parent.
8. For "Sexual reproduction – ______ parents produce genetically unique offspring", "two" is correct as sexual has two parents.
9. For "DNA – All organisms store and transmit ______ information in a molecule called DNA", "genetic" fits as DNA holds genetic info.
10. For "Heredity – the passing on of traits from parents to their ______", "offspring" is correct as heredity is to offspring.
11. For "Metabolism – ______ of chemical reactions in an organism that breaks down or builds up materials", "sum" fits as metabolism is the sum of reactions.
12. For "Multicellular – an organism made up of ______ than one cell", "more" is correct as multicellular has more than one cell.
13. For "Unicellular – an organism made up of ______ cell", "one" fits as unicellular has one cell.
14. For "Evolution – The change in the characteristics of species over several ______", "generations" is correct as evolution is over generations.
15. For "Adaptation – changes in behavior, physiology, and structure of an organism to become more suited to an environment for ______", "survival" fits as adaptation is for survival.
