What is Desert pack rats are active at night to conserve water.
True/False. Life would cease to exist without energy from the sun or some other source.
True
What is the Purpose of an Enzyme?
speed up chemical reaction by lowering activation energy
This property of water allows water to "climb" up substances.
Capillary Action
This type of data is measured with some type of instrument to get results. (beaker, stop watch, thermometer, etc)
Quantitative Data
This feedback mechanisms tries to increase the intensity of the disturbance (ex blood clotting)
What is positive feedback loop
