Science advances through legitimate skepticism. Scientific investigations sometimes result in new ideas and phenomena for study, generate new methods or procedures for an investigation, or develop new technologies to improve the collection of data. All of these results can lead to new investigations. Life Science Structure and function in living systems Living systems at all levels of organization demonstrate the complementary nature of structure and function. Important levels of organization for structure and function include cells and tissues.
Cells carry on the many functions needed to sustain life.
They grow and divide, thereby producing more cells. This requires that they take in nutrients. Reproduction and heredity Reproduction is characteristic of all living systems. Some organisms reproduce asexually. All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions.
