Answer:
C
Explanation:
It is right trust me. It needs a longer beak to reach food in smaller areas and it has adapted to the enviroment in many years
When a cardboard is slowly pulled let's say for example there was a coin which is placed on the top of the cardboard and then the cardboard is pulled slowly the coin which is on top moves with it.
There is a friction force which is being applied between the coin and the cardboard which makes the coin to continue moving with the cardboard.
If it is flicked, the coin will not move will remain and cardboard will move.
The coin did not move because of its tendency to remain at inertia.
Allowing a scientist to hide information from the public and other scientists has many consequences. By hiding findings, it can prohibit other scientists from using the findings to further advance the research process. It is crucial that findings are shared so advancements in things such as medicine, mental health, physical health, and all other sciences can progress to better help people. If, for example, a scientist found that there are links to cancer and sugar, withholding that information from the public would therefore prevent people from taking precautions against cancer.
Answer:
The DNA strands are not free in the nucleus, but forming a compact structure called chromatin along special proteins, known as histones. The chromatin structure has an important role in gene expression, as the level of compaction and the histone modification act as signals for the transcription machinery
In order to be transcribed, different areas in the genome need to unfold from the histone proteins, so the RNA polymerase can access the DNA.
That means, <u>that DNA sequences that transcribe at high rate, are more often unfold from the histones, and more exposed to other proteins to bind them. Particularly, those areas are more sensitive to the attack of endonucleases, such as DNAse I.</u>
As a consequence, an assay of DNAse I digestion can be used to identify highly sensitive or resistant to DNAse cleavage areas in the genome, and therefore serve as an insight to which sequences are more and less transcriptionally active.
