show A membrane-enclosed structure with a specialized function within a cell.  
🗑
show A group of two or more atoms held together by covalent bonds  
🗑
show New properties that emerge with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases.  
🗑

🗑
show A type of cell lacking a membrane-enclosed nucleus and other mebrane-enclosed prganelles; found only in the domains bacteria and archaea  
🗑
show A type of cell that has a membrane-enclosed nulceus and other membrane-enclosed organelles. All organisms except bacteria and archaea are composed of eukaryotic cells.  
🗑
show an approach to studying biology that aims to modle the dynamic behavior of whole biological systems.

🗑
Hypothesis   show
🗑
show a widely accepted explanatory idea that is broad in scope and supported by a large body of evidence  
🗑
show a component of the process of science whereby a scientist carries out two parallel tests, an experimental test and a control test. The experimental test differs from the control by one factor, the cariable.
