Answer:
Because there is a mutation in region one that causes high level expression even in the absence of ethanol, region 1 must bind a transcriptional repressor and regulation of gene X must occur by relief of repression. Since a mutation in gene 2 results in a uninducibility of the gene, region 2 must bind a transcriptional activator. in the absenece of an activator the reprssor becomes irrelevant and the gene is in active regadless of conditions. Mutations in both regions 1 and 2 have the same effect as a single mutation in region 2, because in the absence of a bound transcriptional activator the repressor is irrelaevnat and the gene is inactive regardless of the presence or absence of ethanol
ANSWER: Janice's observation that is explained by Hypothesis I but not by Hypothesis II is that <u>shortly after the candle was covered by the glass beaker, the flame diminished and soon went out.</u>
REASONING:
Hypothesis I mentions oxygen as an important part of the chemical reaction that causes certain objects to burn. By placing the glass beaker over the candle, the oxygen supply is cut off. Once the oxygen inside the beaker is consumed, the flame diminishes and goes out.
Hypothesis II does not mention oxygen as an important part of the chemical reaction.
Cues like these act by changing the activity of core cell cycle regulators inside the cell. These core cell cycle regulators can cause key events, such as DNA replication or chromosome separation, to take place. They also make sure that cell cycle events take place in the right order and that one phase (such as G_1
1
start subscript, 1, end subscript) triggers the onset of the next phase (such as S).
We can't answer that question because you have not provided us with a picture. Sorry
