Definations
The degree to which the experimental result agrees with the correct value
accuracy
Located on the y-axis
DV
Animals store most of their excess energy reserves as
fat; they store twice as much energy per gram.
The attraction between molecules of the same substance. Water sticking to water.
Cohesion
The degree to which the measurement agrees with one another
precision
What changes in response to the independent variable?
DV
The "cause" or change
Independent variable
list the order in which each macromolecule would be consumed by the body for energy
carbs
lipids
proteins
NEVER nucleic acids
The type of attractions that happens between two molecules
Adhesion
When you describe something you can see, smell, touch, taste or hear
Observation
groups that are used for comparison in the experimental groups. The "normal group"
Control Group
descriptive data
Qualitative data
The smallest part of an element that still has the properties of that element.
atom
The molecule that makes up a majority of the cells membrane structure
lipids
A guess about an object or outcome based on your observations
Inference
Groups that are being tested
Experimental group
Found on the X axis of a graph
IV
Why can ice exsist under frozen water?
Water is less dense as a solid
If available the body will always digest which macromolecule first?
carbs
A testable prediction based on an observation that describes a cause adn effect relationship between variables
Hypothosis
The aspects of an experiment that are help constant/consistent
Constants
How do you create a Hypothesis? (Think of the format)
If "IV" then "DV"
When placing oil in water it does not dissolve it seperate. What does this mean oil is? (Hydrophilic, hydrophobic, polar or non-polar)
hydrophobic and non polar
The macromolecule that would most likely be involved in in contracting muscles would be?
Proteins
