Which of the following statements are correct? Choose all that apply. Which of the following statements are correct? Choose all that apply. During transcription, active genes are brought to the periphery of a territory. The interchromosomal domains are the regions between chromosomal domains, and nothing happens there. Euchromatin is more tightly packed because it has a higher gene density. DNA replication appears to be a well-organized process within the nucleus, but transcription does not appear to have any organization to it. Transcription continues even as a cell has entered S-phase. During replication, DNA is collected in regions where replication machinery is located. All chromatin takes an equal amount of time to access for replication.

Ascientist is investigating the effects of salinity on fish development. he places fertilized fish eggs in an aquarium that contains low salinity and observes their development. what factor would improve experimental design the most? place the fish eggs in the open ocean because that is the natural habitat include another aquarium that has normal salinity to compare to the low salinity aquarium include an aquarium that replaces salt with sugar to confirm that the effects are specific to salt grow algae with the fish eggs in order to provide adequate nutrients to the developing embryos
