What did Darwin conclude about the finches on the Galapagos Islands that later supported his theory of evolution? Check all that apply.

(A) The finches on the Galapagos Islands all had the same beak.
(B) The finches on the Galapagos Islands had different beaks.
(C)The beaks of the finches stayed the same over time.
(D)The beaks of the finches changed over time.
(E)The Galapagos finches had a common ancestor.
(F)The Galapagos finches did not have a common ancestor.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.

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.
