Q: Answer the following question given this paragraph: When lactose is present, the repressor protein does not bind to the operator. This allows RNA polymerase to bind to the promoter and begin transcription. As a result, the lac genes are expressed, and lactose is digested. Q: When lactose is present in the cell, what allows the lac genes to be expressed? Choices: - concentration of repressor protein - binding of expressor protein - the addition of water - nonbinding of repressor protein A:
A: nonbinding of repressor protein
Question: Answer the following question given this paragraph: Spring tides occur during the new moon and full moon. The Sun and Moon must either be in a straight line on the same side of Earth, or they must be on opposite sides of Earth. Their gravitational pull combines to cause very high and very low tides. Spring tides have the greatest tidal range. Q: What occurs during the new moon and full moon, due to gravitational pull? Choices: - spring waves - spring floods - spring storms - spring tides A:
Answer: spring tides

Answer the following question given this paragraph: Physical and chemical properties of geometric isomers are generally different. While cis -2-butene is a polar molecule, trans -2-butene is nonpolar. Heat or irradiation with light can be used to bring about the conversion of one geometric isomer to another. The input of energy must be large enough to break the pi bond between the two carbon atoms, which is weaker than the sigma bond. At that point, the now single bond is free to rotate and the isomers can interconvert. Q: Physical and chemical properties of geometric isomers are generally what? Choices: - round - difficult - similar - different A:
**Answer**
different
