Answer:
D. They block communication between enhancers and non-targeted promoters
Explanation:
Insulator sequences are the group of DNA sequences that protect the protein-coding regions of the DNA from the surrounding regulatory sequences. Some insulator sequences are present between the enhancers and promoters of a gene. These insulator sequences do now allow these enhancers to regulate the expression of genes by sending inappropriate signals.
However, if the insulator sequences are not present between the enhancers and promoters of certain genes but are located somewhere else, enhancers can upregulate the expression of these genes.
Answer:
Not using control cases and testing his hypothesis only on one pacient, himself. Not creating or using a method that allowed him to measure the results.
Explanation:
During the investigation Alon had a few methodological flaws. First of all, he based a hypothesis over only one case, his own. He should have tested the product on different pacients under similar circumstances, the more the merrier. Moreover, it is not recommended that the investigator tests the hypothesis on himself, since he can lose perspective.
Second of all, he did not use control cases. This means he should have given placebo pills (pills with no medical effect at all) to a group of pacients without them knowing. Doing this helps eliminating the psicologycal factor of the equation, since pacients have proven to get better, in some cases, just because they thought the medicine would heal them, and not because of the drug itself.
Also, he came to a conclusion based on how anxious and worried he felt after the treatment, but expresses the results with words such as <em>"much more"</em>. In this case he should have created and/or used a method to measure the change in anxiety and how much the pacient worried. For example, before starting the test he could have rated his anxiety level from 1 to 10, and then, done the same thing during and after the treatment was over. By doing this he creates data that can be numerically processed and makes the human subjectivity factor smaller.
I'd say probably Biomass, not 100% sure but it's renewable, but it can create power and heat.
