OAE 055- Questions and Answers
asexual reproduction Correct Ans-offspring created out of an exact copy of the parent through
mitosis, genetically identical
ex. Bacteria
Meiosis Correct Ans-Cell division that produces reproductive cells in sexually reproducing
organisms new cell created is called zygote
Phenotype vs. Genotype Correct Ans-- Phenotype: expressed physical traits
- Genotype: Genetic make-up
Heterozygous Correct Ans-having two different alleles for a trait (Bb)
ionization energy Correct Ans-The amount of energy required to remove an electron from an
atom
increases in each period from left to right across the periodic table, and increases in each group
from bottom to top
electron affinity Correct Ans-the energy change that occurs when an electron is acquired by a
neutral atom
,increases left to right, bottom to top
atomic radius Correct Ans-size of an atom. decreases from left to right (b/c of increased
nuclear charge). Increases from top to bottom (b/c you have added an energy level)
physical and chemical properties Correct Ans-physical properties are unique for a particular
substance and include color, density, melting point and boiling point.
chemical properties relate to how a substance interacts with another substance
Flammability, Toxicity, pH, Radioactivity, Oxidation state
Electronegativity
Reactivity
matter and energy are always Correct Ans-conserved
electromagnetic waves Correct Ans-A form of energy that can move through the vacuum of
space (no medium)
light and radio
period vs wavelength Correct Ans-Period (T): Time (time vs pressure graph)
*Wavelength* (λ): *distance* between two crests
, longitudinal wave Correct Ans-A wave in which the vibration of the medium is parallel to the
direction the wave travels
transverse wave Correct Ans-A wave in which the particles of the medium move
perpendicularly to the direction the wave is traveling
ion Correct Ans-A charged atom
Newton's 3 Laws Correct Ans-1) An object at rest wants to stay at rest and an object in
motion wants to stay in motion unless acted on by an outside force.
2) Force equals Mass times Acceleration. F=MA
3) For every action there is an equal and opposite reaction.
oral language skills help develop Correct Ans-reading and writing skills
passive solar energy Correct Ans-heat for homes and buildings
Elementary choirs usually sing music arranged for unison voices and/or: Correct Ans-two-or
three-part soprano
