Ascientist performs an experiment in which they create an artificial cell with a selectively permeable membrane through which only water can pass. they inject a 5m solution of glucose into the cell and then place the cell into a beaker of water. after an hour, what effect do you expect to observe? a) water moves out of the cell. b) water moves into the cell. c) glucose moves out of the cell. d) glucose moves into the cell. e) no net change in cell weight.

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

the correct option is option d

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.
