The cells were first observed using a compound microscope. This microscope was used by Robert Hooke in the year 1665 who observed thin slices of cork under the compound microscope and saw structures which resembled small rooms and thus he named them as cells.In reality what he actually observed were the dead plant cells.

Answer from: kayli53531

The cells were first observed through compound microscope.

Further Explanation:

Robert Hooke used compound microscope to observe the cork cell which leads to the discovery of the cell in 1665. The microscope was designed by him to observe a piece of cork where he saw tiny units stacked together and he named those units as “cell”. He didn’t see any organelles inside the cell as he observed the dead plant cell with cell walls which resembled like small room. The compound microscope is used to view magnified images of the sample present in the glass slide and the magnification power used by Robert Hooke is 50X. The experiments and observations made using various lenses were recorded in his book called Micrographia or some Physiological Descriptions of Minute Bodies made by Magnifying Glasses with Observations and Inquiries Thereupon.

The cell is the structural and functional unit of an organism where plants and animal cells contain different cellular organelles with specific function.

Answer from: Quest

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.

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
