Is it better for a cell to have a large surface area to volume ratio or a small surface area to volume ratio. a) small: because the cell has more contact with its surroundings. b) small: because a cell with more volume has more space for its organelles. c) large: because the cell has less contact with it surroundings. d) large: because the cell has more contact with its surroundings and can better take in nutrients.

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.
