Answer:
With the phosphodiester backbone and with the bases via the minor groove
Explanation:
Nucleosomes form hydrogen bonds with the DNA to allow for the compacting of the DNA in eukaryotic cells. The nuceosomes consists of histone octamer surrounded by several base pairs wrapped in an helical manner.
The DNA interacts with the nucleosomes via it's histone octamer; the minor groove of that DNA bonds with the base pairs of that nucleosomes mostly the A:T base pairs more than the G:U; the phosphodiester backbone of the DNA.
I think it’s living things
Answer:
B. Hermit crabs and fish that hide in shells compete with each other for shelter.
Explanation:
Hermit Crabs hides from their predator by hiding in old seashells (e.g those of gastropods) for protection and/or shelter. This is a form of camouflage exhibited by hermit crabs for survival. Now, if peradventure some species also uses the same mechanism for adaptation and survival, vigorous competition will sets in between hermit crabs and those species because the availability of empty shells ata ny given place depends on the relative abundance of gastropods which is crucial for the survival of both organisms from their predators. Sometimes, they may even have to fight or kill a competitor in order to gain access to the shell that favors them.
Im pretty sure they are secondary consumers, since the main ones are the predators and omnivores.
