What is the difference between the full classification of organisms and their scientific names?

• The full classification of organisms and their scientific names vary in different countries.

• The scientific names of organisms include the order and family of the organisms, but the full classification includes only the species name.

• The scientific names of organisms include a single nomenclature, but the full classification includes various nomenclatures.

• The full classification of organisms will include more categories of organisms than their scientific names.

The use of pesticides on crops has been a common farming practice for decades. What has been the greatest effect of natural selection through the use of pesticides on certain insect populations?

• Natural selection has been altered because the insects and their predators are killed.

• The rate of selection is increased because the pesticides do not kill the insects that are naturally resistant to it.

• The rate of selection has decreased because the pesticides kill only young insects.

• The pesticides have altered natural selection by causing the insect DNA to spontaneously mutate.

The inheritance of short wings in Drosophila fruit flies is an x-linked recessive trait. Which would most likely result if a short-winged female mates with a long-winged male?

• All offspring will be short-winged.

• All females will be long-winged, and all males will be short-winged.

• All females will be short-winged, and all males will be long-winged.

• Half of the males and females will be short-winged and half will be long-winged.
