(Question)
Answer the following question given this paragraph: Make sure formulas of all reactants and products are correct before balancing the equation. Oxygen gas is a diatomic molecule. Potassium oxide is an ionic compound and so its formula is constructed by the crisscross method. Potassium as an ion becomes K + , while the oxide ion is O 2 . Q: What kind of atomic molecule is oxygen gas? Choices: - aromatic - symbiotic - dramatic - diatomic A:
(Answer)
diatomic

Answer the following question given this paragraph: For example, remember that for the height gene in pea plants there are two possible factors. These factors are alleles. There is a dominant allele for tallness (T) and a recessive allele for shortness (t) . Q: What factors determine the effect of a gene? Choices: - metabolites - genomes - ribosomes - alleles A:
(Answer)
alleles

(Question)
Answer the following question given this paragraph: 27.8 Polarization Polarization is the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave. EM waves are transverse waves that may be polarized. The direction of polarization is defined to be the direction parallel to the electric field of the EM wave. Unpolarized light is composed of many rays having random polarization directions. Light can be polarized by passing it through a polarizing filter or other polarizing material. The intensity I of polarized light after passing through a polarizing filter is I = I 0 cos 2 , where I 0 is the original intensity and is the angle between the direction of polarization and the axis of the filter. Polarization is also produced by reflection. Brewster's law states that reflected light will be completely polarized at the angle of reflection b , known as Brewster's angle, given by a statement known as Brewster's law: reflected light travel and. Q: What type of light is composed of many rays having random polarization directions? Choices: - reflected light - polarized light - diffracted light - unpolarized light A:
(Answer)
unpolarized light
