The main benefit of genetic biodiversity is:
Genetic biodiversity helps populations adapt to environmental changes.
Higher genetic diversity within a population increases the likelihood that some individuals will possess traits that allow them to survive and reproduce in changing environments.

Neutral mutations occur when a mutation is found in a DNA region and results in a harmful disease.
Neutral mutations occur when a mutation is found in a DNA region and results in a harmful disease.
Neutral mutations occur when a mutation is found in a DNA region that codes for proteins.
Neutral mutations occur when a mutation is found in a DNA region that codes for proteins.
Neutral mutations occur when a mutation in a DNA region provides an advantage that helps the organism survive.

The true statement is:
Neutral mutations occur when a mutation in a DNA region results in the same sequence as the original.
Neutral mutations typically do not have a significant effect on the organism's fitness and can occur in non-coding regions or result in synonymous changes (where the amino acid sequence remains the same due to the redundancy of the genetic code).
Three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow. One plant grew to have a purple flower while the other two grew white flowers. What is the most likely conclusion that can be made for the change in flower color?(1 point)
Responses
Environmental factors caused a genetic mutation that caused the differences in flower color.
Environmental factors caused a genetic mutation that caused the differences in flower color.
Genetic factors caused environmental changes that caused the differences in flower color.
Genetic factors caused environmental changes that caused the differences in flower color.
Environmental conditions caused the differences in flower color.
Environmental conditions caused the differences in flower color.
Genetic factors caused the differences in flower color.
Responses
Environmental factors caused a genetic mutation that caused the differences in flower color.
Environmental factors caused a genetic mutation that caused the differences in flower color.
Genetic factors caused environmental changes that caused the differences in flower color.
Genetic factors caused environmental changes that caused the differences in flower color.
Environmental conditions caused the differences in flower color.
Environmental conditions caused the differences in flower color.
Genetic factors caused the differences in flower color.
The most likely conclusion that can be made for the change in flower color is:
Genetic factors caused the differences in flower color.
Since the plants were grown under the same environmental conditions, the difference in flower color is most likely due to inherent genetic variations among the plants rather than environmental factors.
A scientist sets up terrariums in a laboratory and observes the growth of lizards in each terrarium. Which of the following observations could be used as evidence that the amount of space in an environment can affect an animal's growth?(1 point)
Responses
Two lizards of the same species grow to different sizes in the same terrarium.
Two lizards of the same species grow to different sizes in the same terrarium.
Two lizards of the same species grow to different sizes in different-sized terrariums.
Two lizards of the same species grow to different sizes in different-sized terrariums.
Two different species of lizard grow to different sizes in the same terrarium.
Two different species of lizard grow to different sizes in the same terrarium.
Two lizards of the same species grow to different sizes in terrariums with different food supplies.
Responses
Two lizards of the same species grow to different sizes in the same terrarium.
Two lizards of the same species grow to different sizes in the same terrarium.
Two lizards of the same species grow to different sizes in different-sized terrariums.
Two lizards of the same species grow to different sizes in different-sized terrariums.
Two different species of lizard grow to different sizes in the same terrarium.
Two different species of lizard grow to different sizes in the same terrarium.
Two lizards of the same species grow to different sizes in terrariums with different food supplies.
The observation that could be used as evidence that the amount of space in an environment can affect an animal's growth is:
Two lizards of the same species grow to different sizes in different-sized terrariums.
This observation directly indicates the influence of space on the growth of the lizards, as it compares the same species in environments that differ in size.
A species of fox lives in the arctic where the ground is covered in white snow most of the year. These arctic foxes hunt rodents and other small mammals, while their predators include eagles, wolves, and polar bears. A mutation in its DNA causes a fox to have white fur rather than brown. Given this information, would you classify this mutation as a harmful, beneficial, or neutral mutation? Would this make the fox more or less likely to survive? Explain your answer.
The mutation that causes the arctic fox to have white fur rather than brown would be classified as a beneficial mutation.
Explanation:
-
Camouflage: In the arctic environment where the ground is covered in snow most of the year, white fur would provide better camouflage for the fox against predators like eagles, wolves, and polar bears. This increased ability to blend into its surroundings would help the fox avoid being detected by predators.
-
Hunting Efficiency: Additionally, the white fur would also aid the fox in hunting for its prey, such as rodents, as it would be less visible to these animals as well.
Likelihood to Survive:
Given these advantages, the fox with white fur would be more likely to survive in its arctic environment compared to a brown-furred fox. The mutation enhances its survival prospects by improving its ability to evade predators and effectively hunt for food, contributing to a greater likelihood of reproduction and passing on the beneficial trait to future generations.
