What are the three domains of life? - correct answer domain bacteria, domain archaea,
domain eukarya
Biology is.. - correct answer the study of living organisms and their interactions with one
another and their environments. Very Broad and Diverse
Chemistry is.. - correct answer .. the study of reactions
What are the seven properties an organism must have to be considered alive? - correct
answer 1- Order (pattern/ blueprint),
2- Response to Stimuli (dna / ability to change over time),
3- Reproductive capabilities
4- Adaptation (must adapt to environment)
5- Growth and development (required for reproductive abilities),
6- Regulation (of environment, Cope with environmental structures)
7- Homeostasis (Regulating internal temperature , pH)
8- Energy processing (all things process energy used to power process ex.
Photosynthesis, food)
Bacteria - correct answer Its own domain and Kingdom
single-celled, microscopic organisms
Domain Archaea - correct answer Its own domain and Kingdom
single-celled microscopic organisms, live in extreme environments
Domain Eukarya - correct answer Protista, Fungi, Plantae, Animalia
,have a greater diversity in form than bacteria and archaea. eukaryotes include single-
celled and multi-cellular organisms.
Extremophile - correct answer can survive in extreme environments
Experimental study - correct answer changing/ manipulating situations/ variables and
monitoring effects
Observational study - correct answer observing and measuring characteristics/
situations without manipulation
List the seven steps of the scientific method. - correct answer Observation, Question,
Hypothesis, Predictions, Testing, Results, Conclusion
Evolution and Natural Selection - correct answer -Genetic change of a species over
time
-Mechanism of evolution
(Short neck giraffe dies off, Long neck giraffe lives)
Cell Theory - correct answer the smallest unit for a living thing is a cell
Gene Theory - correct answer anything can be inherited, inherited traits are coded for in
DNA
Homeostasis - correct answer self regulation of internal environment
Independent Variable (IV) - correct answer the variable that is being manipulated by the
experimenter
Dependent Variable (DV) - correct answer the thing being measured ... should be the
thing that depends on the IV
Controlled Variable (CV) - correct answer difference between groups that experimenter
tries to keep constant
Control Group - correct answer no exposure to IV
Blind Study - correct answer participants do not know if they are being given treatment/
are unaware of the experiment
Double-blind Study - correct answer An experiment in which neither the participant nor
the researcher knows whether the participant has received the treatment or the placebo
Placebo - correct answer false treatment
, Name the four components of Dalton's Theory - correct answer 1- All matter is made of
atoms & atoms are indivisible/ indestructible. 2- All atoms of a given element are
identical in mass & property. 3- Compounds are formed by a combination of 2+ atoms.
4- A chemical rxn is a rearrangement of atoms.
Which components of Dalton's Theory are incorrect? - correct answer Atoms are
divisible and can be split (atom splitting!). Isotopes of atoms exist where multiple of the
same element can have different masses from each other.
Describe the structure of an atom - correct answer atoms have three subatomic
particles. neutrons and protons are contained in the nucleus which has a net positive
charge. the outside of the atom is a cloud of electrons which are negatively charged.
Electrons - correct answer negatively charged subatomic particles. electrons in the
outer shell are what decides an atom's reactivity properties.
Neutrons - correct answer subatomic particle with a mass of 1, nearly equal to mass of
a proton (1). neutral charge.
Protons - correct answer positively charged subatomic particle with the same mass as a
neutron (1).
Equal to Atomic Number
Atomic Number - correct answer the number of protons in the nucleus of an atom. this is
the identity of the atom.
Atomic Mass - correct answer the number of protons + the number of neutrons in the
nucleus
orbitals - correct answer concentric rings containing electrons. the 1st orbital contain
maximum 2 e-, the 2nd and 3rd contain a max of 8 e-
Isotope - correct answer versions of elements with different numbers of neutrons. for
example, C-14 breaks down over time. C-14 behaves differently than C-13 & C-12
which behave similarly.
What are the three types of bonds? - correct answer ionic bonds, covalent bonds, &
hydrogen bonds
Ionic bonds - correct answer involve the attraction of opposite electrical charges
chemical interaction involving the transferring of electrons
