(what an organism does) (what an organism is…shape & form of the body) This is behavioral because it is what the animal does. SPI 0807.5.2 Adaptation Notes Science

3. Two Key Behavioral Adaptations: (1)Sexual Reproduction- (2)Asexual Reproduction- (requires 2 parents: male & female) (requires only 1 parent) SPI 0807.5.2 Adaptation Notes Science Reproduces sexually Dogs Hydra Reproduces asexually
