he Pacific Ocean. She concludes the fish populations are always large close to the coasts throughout all oceans. Why is this an invalid scientific conclusion?
a. She needs less data to draw conclusions.
b. Scientists should repeat this experiment at different sites to draw conclusions.

Answer:

Option B

Explanation:

When ever a scientific research or experiment is conducted , it is made sure that the results obtained are consistent through multiple trials. Here , only two trials are done i.e one on coast of California and the other on the Pacific Ocean.

Since the number of samples taken for this study are not as per the standard sample guidelines and hence the result obtained can not be considered as a acceptable.

Thus, option B is correct

The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no oth
KIM [24]

Answer:

The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.

Explanation:

Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.  

With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
