Most enzymes belongs to which group of macromolecule- proteins.
How might ions, such as H+ cross a plasma membrane- by facilitated diffusion (passive transport)
Light independent of photosynesis- 6 molecules of CO2 are used to build one molecule of glucose.
Light dependent reactions of photosynesis- splitting water.
How is membranes involved in photosynesis- passed through an electron transport system embedded in thylakoid membranes.
Observation: phenomena that can be sensed.
Hypothesis: description used to explain observations.
Theory:explanatory framework that ties disparate observations together.
Law:description of a set of observation about nature.
Experiment: used to test hypotheses, theory’s and laws.
Living v.s non-living:contain DNA, respond to environmental change, acquire energy and use it to maintain organizations
Diffusion: movement of a substances from a high concentration of area to low energy required.
Osmosis:water moves from an area of high concentrates to low, through selectively permeable membrane
Scientific Method:observation,hypothesis,design experiment,prediction,experiement,conclusion,yesorno
Photosynthesis: CO2 are used to build
