It must be based on scientific observations that can be repeated in a controlled setting, would be the correct answer.
Angiosperms are flowering plants, so I'd say flowers and the parts of flowers are a pretty common characteristic.
Answer:
False
Explanation
There is no substantial difference in electronegativities that would create a polar bond... electrons would NOT be unevenly distributed in O2, meaning that the molecule has a nonpolar covalent bond
Answer/ Explanation:
Chromosomes are highly condensed and compact structures. This means the chromatin (protein plus DNA complex) is hierarchically organised into tight structures through progressive folding of chromatin.
However, this is only the case during cell division. When the cell is in interphase and performing its normal duties, it is in a much more decondensed structure. This is because in order for transcription to occur, the cell needs to be able to access the information in the DNA. For example, transcription factors need to bind at their gene promoters to promote transcription.
When the DNA is folded into chromosomes, cellular factors do not have access to the genetic information due to the physical constraints of the chromatin structure.
