people learning to ride horses for exercise

a plant species has evolved to contain a bad-tasting chemical. which of the following is the most likely outcome of this adaptation?
question 5 options:

the plant will be able to live in many different environments.

the chemical will aid in photosynthesis.

animals are more likely to eat the plant.

animals are less likely to eat this plant.

white sands, new mexico, is an area of desert where the ground is white instead of dark. lizards living in other parts of the desert have dark, striped skin. many lizards of the same species living at white sands have white skin. what is the most likely reason for this?
question 4 options:

the white sand causes the lizards' skin to turn white.

white skin is a favorable adaptation because it makes the lizards hard to see against the white sand.

white skin is a favorable adaptation because it makes the lizards poisonous.

white skin is a favorable adaptation because it the lizards stay cool in the sunlight.

which of the following is not part of the theory of natural selection?
question 3 options:

organisms compete for limited resources.

organisms vary in their physical traits, and traits are inheritable.

organisms produce fewer offspring if the environment does not have enough resources.

organisms best suited to their environment will survive and reproduce.

which scenario is an example of natural selection?
question 2 options:

dogs that have a desirable coat color are bred with one another to produce puppies with the same coat color.

people kill ratllesnakes that rattle when approached by humans, but people do not kill rattlesnakes that remain silent. the quiet snakes survive and breed.

farmers crossbreed two types of cows to produce a breed of cow that has high quality beef and can tolerate a hot climate.

giraffes that have long necks survive a dry season by eating leaves from the tops of trees. those giraffes breed more successfully that year.

over a period of years, the average rainfall in an area has decreased, causing environmental changes. most likely to survive these environmental changes is a population
question 1 options:

that has been altered through artificial selection.

with the smallest population size.

with a great amount of genetic variation.

with very little genetic variation.
