Within ten years after the introduction of a new mosquito spray, very few of the descendants of the targeted mosquito populations were killed by the usual dose of the spray. The best explanation for this is that
ingesting the spray caused the mosquitoes to become resistant to it
the spray killed organisms that caused diseases in mosquitoes
existing variations in the mosquito population provided resistance to the spray
he spray polluted the water in which the mosquitoes deposited their eggs
Mutations can be beneficial to a species because they
allow organisms to mate with other species
can lead to some members of a species having favorable traits in a changing environment
will lead to the loss of traits that are helpful in a specific environment
cause the reproductive rate of a species to decrease
A certain species of rough-skinned newt produces an extremely powerful toxin that helps prevent attacks by predators. However, one predator, the garter snake, can eat these newts without being affected by the toxin. Which statement best explains the resistance of garter snakes to the newt toxin?
Exposure to newt toxin caused a mutation in the snakes, which increased resistance to the toxin in the snakes.
As the newts became more toxic, the snakes became increasingly resistant in order to survive.
A random genetic mutation that resulted in toxin resistance increased the survival rates of the snakes that had it, and they passed it on to their offspring.
The snakes needed to become resistant to the toxin in order to survive, so they developed a toxin-resistance gene.
