Answer:
10%
Explanation:
Chargaff postulated the complementary base pairing rule, where he stated that in the DNA molecule, Adenine (A) will always pair with Thymine (T) and Guanine (G) with Cytosine (C) i.e. A-T, G-C
Chargaff stated that the concentration of purines (Adenine and Guanine) is always equal to that of pyrimidines (Thymine and Cytosine) i.e. {A} + {G} = {C} + {T}
These equal concentration equals 100% in totality i.e. A+G+C+T= 100%
Thymine pairs with Adenine, if there is 40% of Thymine in the DNA molecule, it means there will be 40% of Adenine also. 40 + 40 = 80%. This leaves us with 100-80 = 20% for Guanine and Cytosine.
Since there will be an equal amount of Guanine and Cytosine too, Guanine will therefore, be 20/2 = 10%.
That is, 10% Guanine, 10% Cytosine.
The economic implications have to do with agriculture. Look what happens when there is an outbreak of mad cow or hoof and mouth disease. Thousands of farmers lose their herds and are financially devastated. This also affects the consumer because the decrease in supply will drive up the costs. But, it could also have the opposite effect. If consumers no longer feel safe, then they will stop eating the particular food and the farmers will lose money.
The same is true with disease in plants. Tobacco mosaic virus can devastate crops, resulting in huge economic losses. On a grand scale, crop diseases can affect human history. Potato blight caused suffering and death in Ireland and resulted in massive migration. Many descendents from Irish folks in the U.S. wouldn't be here if it weren't for a crop disease.

Answer:
The correct answer is - speciation is sympatric.
Explanation:
Sympatric speciation is a process of speciation that takes place when there is reproductive isolation between two populations of a species without any geographical separation.
This speciation takes place in the population with come ancestors as given in the question both pods of dolphins lose their ability to interbreed due to the sympatric speciation without any geographical separation.
Thus, the correct answer is - speciation is sympatric.
