You are looking through a light microscope with a 10x eyepiece trying to determine what type of cells you are seeing. You can only see individual cells with 100x total magnification. What type of cell is it, and how much detail would you expect to see? A Prokaryotic cell, very little detail

B Prokaryotic cell, much detail

C Eukaryotic cell, very little detail

D Eukaryotic cell, much detail

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

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.
