What is true about the replication forks formed at each replication origin? Group of answer choices At each fork, the replication machine opens up the double helix and uses each DNA strand to make new daughter strands. Replication forks are X shaped. One replication fork is formed at each replication origin. The two forks formed at each replication origin move in the same direction, working together to unzip the DNA double helix and replicating the DNA as they go. DNA replication in bacteria and eukaryotes is unidirectional, In that DNA is replicated in only one direction.

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
