He 10 nm fiber and the 30 nm fiber are two chromatin structures that differ in width. which comparison between these two structures is false? -a solution of 10 nm fibers can be induced to form 30 nm fibers by addition of histone h1-linear dna is more heavily compacted in the 30 nm fiber-in the 30 nm fiber, more dna is associated with nucleosomes and the linker dna is shorter-formation of the 30 nm fiber requires the tail domains of the core histones-dna is more accessible to the enzymes that regulate its function in the 30 nm fiber

b because they naturally adapt to their environment plz mark brainliest

explanation:

the titanic would be the correct answer

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
