Consider the heating curve of H20 and line segments A, B, and C. Several changes are taking place at A, B, and C. AL BUT ONE would
be an appropriate description as we move through segments A, B and then
A)
Temperature is increasing
Kinetic energy is increasing
Space between molecules decreases
Molecular attraction is decreasing

not sure if this what   you'r looking for would be percent composition

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher

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.
