I think it would be D. because in our text book it says and i quote

"The rate of speciation and extinction varies from clade to clade. Some clades contain many species that have survived for long periods of time. Other clades have only a few species, which soon become extinct."

EleoNora [17]

The ecological footprint of the average people of Bangladesh  is 0.5 global hectares per person which much less than  average of the world ( 2.84 global hectares per capita ) .it indicates that a low purchasing power of Bangladesh . less consumption means less production .also there are few industries in Bangladesh. This is the reason the ecological footprint of Bangladesh is so small .

The United states ecological footprint is larger than that of other countries because per capita consumption of energy and a wide range of goods of all kinds is greater . wastes ,including carbon dioxide ,are greater as ell , adding to the relative size of the footprint . this is the reason the ecological footprint of the people of United states is large .

Hence ,the ecological footprint of Bangladesh  is so small and the ecological footprint of United states is so large .

This is a DNA mutation that does not result in a change to the amino acid sequence of a protein.
ohaa [14]

Answer: silence point

A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.
