A young scientist has discovered a new species of grub worm in the Amazon. He would like to explore the possibility that in this grub worm the codon CUC is the start codon and codes for methionine, not leucine as it does in other worms. To date, he has been unable to get his research funded, most likely because

A) worms have been extensively studied and their genomes are simple.
B) the genetic code is universal to all species.
C) worms do not contain homologous genes to humans.
D) worms are difficult to maintain in the laboratory.
E) codons are generally the same in all worms.

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.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.

i think the answer is a.keratin is the pigment responsible for skin color.
