• Variation 
• Adaptation
• Natural Selection

A trait that an organism expresses during its lifetime will only cause its species to become better adapted if the trait—

• A.  Results from isolation of the organism from the rest of the population 
• A.  Is caused by the genetic code that is present in the gametes of the organism
• A.  Causes a change in the environment surrounding the organism
• A.  Decreases the number of genes in the body cells of the organism

A graph regarding the effect of agricultural bioengineering on insect pests is shown below How has natural selection affected species of insect pests?

• A.  Natural selection has not affected the number of species that are resistant to pesticides
• A.  Natural selection has rapidly increased the number of species that are resistant to pesticides
• A.  Natural selection has only affected the number of species that are resistant to pesticides
