Scientists recently identified the function of three proteins in plants. the proteins regulate the production of fatty acids, which are found in fats and oils. which question will most likely be asked about the results, leading to more investigations?
how are proteins produced?
are the plants nonrenewable resources?
how much energy do fatty acids produce when they are burned as fuel?
how can the proteins be used to increase the amount of oil produced by a plant?

individual oxygen atoms are formed during photosynthesis.-c.

answer: c.

explanation:

the backbone of the dna and rna compound is sugar phosphate.

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.
