Characteristics of Water
The molecular symbol for water.
H2O
Maintaining a constant internal environment.
Homeostasis
BONUS POINTS:
Name an example of homeostasis for +100 points
An educated guess
Hypothesis
Name the 4 types of macromolecules
carbohydrates, proteins, lipids (fats & cholesterol) & nucleic acids.
True or False: All proteins are enzymes but not all enzymes are proteins.
False
All ENZYMES are PROTEINS but not all PROTEINS are ENZYMES.
What property of water is this: Water as a solid is less dense then liquid water.
Ice Floats
In cells, is always DNA (a characteristic of life)
Genetic material
True/False:
Eating/drinking in lab is allowed.
FALSE
This macromolecules' smallest form is monosaccharides
Carbohydrates
Name the 3 types of fatty acids
Saturated, unsaturated & trans fatty acids.
What property of what is this: Takes a lot of energy to boil water
High specific heat
Are considered non-living, but not dead (to be dead you have to have once been alive).
Viruses
This is a base line, the variable that is not changed.
Control
This macromolecule is made of amino acids and has 4 different structures.
Proteins
These are long chains of nucleotides, which are made of 3 parts.
Nucleic acids.
BONUS POINTS:
For +100 points name the 3 parts of a nucleotides.
Measures how many H+ are in the solution (the proportion)
pH
Genetic changes in a population over generations
Adaptations
BONUS POINTS:
Give an example of adaptations for +100 points
This is the variable being tested and measured in a scientific experiment
Dependent variable
Cellulose, starch, glycogen & chitin are all examples of what macromolecule?
Carbohydrates
This type of fatty acid is considered very bad for you and do not occur naturally. They are unsaturated fatty acids that have been artificially straightened.
Trans fatty acids.
Describes oxygen in the water molecule, it doesn't share electrons evenly and is "greedy".
Electronegative
Hierarchy, little things make up big things. (A characteristic of life)
Organization
This variable is the variable that is changed or controlled in a scientific experiment to test the effects on the other variable.
Independent variable
Name the 4 structures of proteins
Primary, secondary, tertiary and Quaternary structures.
These are made of a phosphate group and 2 lipid chains.
Phospholipids
