- How do you write a proper hypothesis?
-
IF...(independent variable)...
THEN..(Dependent variable prediction) - Active Transport
- Requires energy to work against diffusion.
- Multicellular organism
- made of many cells,the individual cells have specialized jobs.
- Osmosis
-
The diffusion of water through
a cell membrane. - Dependent Variable
- What you measure (try to find out) during an experiment.
- Passive transport
- Movement of molecules in the flow of diffusion. Requires no additional energy.
- Equilibrium
- When a balance is achieved.
- Shape of cells
- Help with job (ie Red blood cells are small and smooth, muscle cells long and thin, white blood cells can engulf).
- Metabolism
- Sum of all chemical activities.
- Unicellular
- Made of 1 cell. It can perform all of life's functions independently.
- Respiration
- Provides you with energy needed for life's functions.
- Levels of organization
-
cells-tissues-organ-
organ system-organism - 6 characteristics of living things
-
-made of cells -Have DNA
-Grow and develope -Reproduce
-Respond to stimuli
-Use energy - 4 needs of living things
- water, food, shelter, air
- Photosynthesis
- Producers use this to make glucose (oxygen also produced).
