Test 1 Flashcards
Condition when the inside of a cell has a higher solute than the outside of the cell.
Hypotonic
The variable that the experimenter manipulates.
Independent Variable
Multiple polypeptides bonded together is what level of protein structure?
Quaternary
When your body sweats, the water evaporates from your skin, taking heat from your body with it, cooling you down. Which property of water does this describe?
Heat of Vaporization
Water molecules stick to other water molecules.
Cohesion
Breaks down fatty acids and amino acids.
Peroxisome
Regulates water concentration.
Vacuole
What type of bond forms between amino acids to form proteins
Peptide bond
Linking molecules together to make a larger molecule and removing a water molecule.
Dehydration synthesis
A bond where electrons are given and taken, forming oppositely charged ions that are attracted to one another.
Ionic bond
A bond in which atoms share electrons equally.
Nonpolar covalent bond
Interconnected cells with a common functions
Tissues
Organisms get bigger through internal changes and differences may occur as they age.
Growth & Development
Which two subatomic particles do you add together to get an elements atomic mass?
Proton and Neutrons
Which subatomic particles can be found in the nucleus of an atom?
Proton and Neutron
You have a wilted stalk of celery. What type of solution do you need to put it in to have the celery become stiff again?
Hypotonic
Variables that the experimenter maintains, to limit their impact on the experiment’s results.
Control Variables
The variable that changes in response to the experimenter’s actions. Is generally what is being measured during the experiment.
Dependent variable
Baking soda would be considered
Basic
Lemon juice would be considered.
Acidic
Atomic Number
Top Number
Atomic Mass
Bottom Number
Water is capable of dissolving many different compounds.
Universal Solvent
It takes a relatively large amount of tension to break the surface of water.
Surface tension
Building blocks of carbohydrates
Monosaccharides
The type of molecule that acts as a biological catalyst, speeding up chemical reactions by lowering activation energy.
Enzyme
Atoms of the same element with differing numbers of neutrons.
Isotopes
What type of bond links lipids together?
Ester Bond
The bond that is formed between atoms due to the partial charges formed through their polar covalent bonds.
Hydrogen Bond
Building blocks of proteins, (the monomer of proteins?)
Amino Acids
The movement of water from an area of low solute concentration to high solute concentration.
Osmosis
Organelle responsible for ribosome assembly
Nucleolus
The movement of a substance from an area of low concentration to high concentration.
Active Transport
The name for the particle when an atom gains or loses an electron.
Ion
The change in protein structure due to changing heat or pH.
Denaturization
Organisms maintain a balance inside of their cells.
Homeostasis
Which property of life is described: Living things have a series of leveled structure from atom -> molecules -> organelles -> Cells -> tissues -> Organs -> organ systems -> organism
Ordered Complexity
