The second law of Thermodynamics is that Energy Transformations are never 100% efficient
Select all that are true
Organisms are open systems
Organisms need constant energy inflow because there is a constant outflow
In a closed system, energy leaves the system

Based on this investigation title: The effect of temperature on food vacuole formation in Tetrahymena pyriformis, what is the Independent Variable (IV)?
Tetrahymena pyriformis
Different temperatures amounts (ie. 12, 22, and 30 degrees Celsius)
Number of food vacuoles
Based on this investigation title: The effect of temperature on food vacuole formation in Tetrahymena pyriformis, what is the Dependent Variable (DV)?
Different temperature amounts
Based on this investigation title: The effect of temperature on food vacuole formation in Tetrahymena pyriformis, what is the study organism?
Active sites are the place where part of the enzyme interacts with the substrate
Substrates are the molecules that join with an enzyme at the active site
A protein's final shape determines the protein's function.
