Which example does NOT describe changes due to selective breeding?
Selective breeding
In order to guarantee survival, garter snakes have developed immunity to the rough-skinned newt's deadly toxins.
use empirical evidence to validate the theory and record scientific observations
Lab rats are bred to be white and have poor visyion, which makes them easier to find if they escape.
Natural selection
The large newts increased in population and competed with the small newts for food.
A dog breeder pairing males and females for breeding based on the animals' temperaments
a rat snake randomly mating with a different species of snake so that the species share a common gene pool
A group of students learns that the traits of some organisms change over time because organisms better adapted to the environment tend to survive and produce more offspring. Which term best describes this process?

Rough-skinned newts are highly poisonous organisms. The newt's toxin level is great enough to repel predators, such as snakes. Garter snakes have exhibited a resistance to the toxins, which allows them to prey upon the newts. What explains this?

A farmer owns two chickens. He decides to breed the chickens so he will have more hens lay eggs. Chicken X lays twice as many eggs as chicken Y. The farmer decides to only breed chicken X. What term best describes this process?

When researching hitell other scientists ofs theory of natural selection, Charles Darwin did extensive studies on the Medium Ground Finch of the Galapagos Islands. In order to ensure that a hypothesis is actually a viable theory, a scientist must.

All natural predator of large and small newts are removed from an area. The scientists hypothesize that without natural predators, the small newts will survive at a higher rate. The population of small newts remains constant. Why?
