●● What is deductive reasoning?
Answer: A logical process where conclusions follow necessarily from
premises; often used in hypothesis testing.
●● What is inductive reasoning?
Answer: A logical process where generalizations are made based on
specific observations.
●● What are independent and dependent variables?
Answer: Independent variables are manipulated in an experiment, while
dependent variables are measured to assess the effect of the independent
variable.
●● Define scientific theory.
Answer: A well-substantiated explanation of an aspect of the natural
world, based on a body of evidence.
●● What are the 7 properties of life?
,Answer: Order, evolutionary adaptation, regulation/homeostasis,
reproduction, response to the environment, growth and development,
energy processing.
●● What are emergent properties?
Answer: New characteristics that arise at each level of biological
organization due to the arrangement and interactions of parts.
●● Differentiate between prokaryotes and eukaryotes.
Answer: Prokaryotes are single-celled organisms without a nucleus (e.g.,
bacteria), while eukaryotes have a nucleus and membrane-bound
organelles (e.g., plants, animals).
●● What is evolution?
Answer: The change in genetic frequencies in a population over
generations, often driven by natural selection.
●● What are the three domains of life?
Answer: Bacteria, Archaea, and Eukarya.
●● What is an atom?
Answer: The basic unit of a chemical element, consisting of protons,
neutrons, and electrons.
, ●● What is an isotope?
Answer: Atoms of the same element that have the same number of
protons but different numbers of neutrons.
●● What are valence electrons?
Answer: Electrons in the outermost shell of an atom that are involved in
forming bonds.
●● What is electronegativity?
Answer: A measure of an atom's ability to attract and hold onto electrons
in a chemical bond.
●● Differentiate between polar and nonpolar covalent bonds.
Answer: Polar covalent bonds involve unequal sharing of electrons,
while nonpolar covalent bonds involve equal sharing.
●● What is a hydrogen bond?
Answer: A weak bond formed between a hydrogen atom and an
electronegative atom, important in water's properties.
●● What are the four properties of water essential to life?
Answer: Cohesion, adhesion, high specific heat, and the ability to
dissolve many substances.
