What is Respond to Stimuli
Define Observation
Name the 3 subatomic particles in atoms
What is Protons, Neutrons, and Electrons
Define compound
What is Substance formed by the chemical combination of 2 or more elements in definite proportions.
List the 4 types of macromolecules
What is carbohydrates, proteins, lipids, and nucleic acids
Name 2 characteristics that relate to DNA
What is Reproduction and Grow and Develop
Describe qualitative data
What is data that is descriptive and involve characteristics that cannot be measured
Define Isotope
What is Atoms of the same element that differ only in their number of neutrons.
Name and describe the 2 types of bonds
What is ionic bonds (atoms taking/releasing electrons and becoming ions) and covalent bonds (atoms sharing electrons)
What is proteins that speed up chemical reactions but are not used up in the process. They are very specific, like a lock and key, and only work in certain environmental conditions
What is Homeostasis
"Steady-state", the equilibrium that allows it to maintain normal function
List the steps of the scientific method in order
What is Observe, Form Hypothesis, Experiment and Evaluate, and Theory
Describe what parts of the atom have mass and what parts have charge
What is Mass: from protons and neutrons. Charge: from protons and electrons
Describe hydrogen bonds
A weak attraction between a partially positive hydrogen and a partially negative other atom
Describe the structure and function of nucleic acids
What is made of nucleotides joined together into DNA or RNA, and function to transmit hereditary information
Name 2 ways that organisms can process energy
What is photosynthesis, metabolism from caloric foods
Explain independent and dependent variables
What is Independent: The thing being manipulated by the experimenter, does not depended on other variables in the experiment. Dependent: the thing being measured, it's outcome relies on the independent variable
Name what Greek philosopher the atom came from
What is Democritus
Describe cohesion, adhesion, and 3 important properties of water
What is cohesion: •Attraction between molecules of the same substance. Adhesion: Attraction between molecules of DIFFERENT substances. Properties: surface tension, capillary action, expanding when freezing, heat capacity
List the monomers of proteins, what binds them together, and what they are called when joined together
What is amino acids, peptide bonds, and polypetides
Define dead, alive, and nonliving
What is not possessing all 7 but did, possessing all 7, never possessed all 7
Explain Peer Review and Bias
Peer review prevents bias (which is personal, not scientific, opinion) and helps and ensure the work meets standards set by the scientific community. Does not ensure data is correct
Describe how to determine the number of valence electrons in an atom
What is the group number it is in on the periodic table
Name and describe 2 types of weak interactions
What is Van der Waals (Weak interactions between oppositely charged areas of nearby molecule) and Hydrogen Bonds (A weak attraction between a partially positive hydrogen and a partially negative other atom)
List the levels of protein structure and what they are
