A scientist creates fruit fly larvae with a mutation that eliminates the exonuclease function of DNA pol III. Which prediction about the mutational load in the adult fruit flies is most likely to be correct?
1. The adults with the DNA pol III mutation will have significantly more mutations than average.
2. The adults with the DNA pol III mutation will have slightly more mutations than average.
3. The adults with the DNA pol III mutation will have the same number of mutations as average.
4. The adults with the DNA pol III mutation will have fewer mutations than average.

B.The adults with the DNA pol III mutation will have slightly more mutations than average.

the answer is c. it will give up it's valence electron to the other atom.

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.
