Which statement is the most likely explanation for why the mouse population changed over time? The hawks eat more dark mice than white mice because the dark mice taste better. The white mice are able to reproduce more successfully than the dark mice do.
Full Answer
What is happening to the mice over time?
What is happening to the mice over time? Students should notice the frequent mouse births and deaths, evidence of the many generations of mice, which is critical for recognizing that the fur color of the population changes.
How long do mice live in the simulation?
Deer mice live about 2 or 3 years (both in the simulation and in the wild). This is another way to focus on the population and help students to see the passing of generations. Does the fur color of the population change over time when hawks are present?
How do mice adapt to their environment?
"The mice can survive by blending into their environment." "The mouse's fur color changes, so it won't be seen and eaten by the hawk." It's not uncommon for new biology students to talk about individual organisms “adapting to their surroundings.”
What should a student notice when studying mice?
Students should notice the frequent mouse births and deaths, evidence of the many generations of mice, which is critical for recognizing that the fur color of the population changes. How long does a mouse live?

Which of the following describes how a large mouse population with high genetic diversity will most likely be affected by a sudden significant environmental change?
Which of the following describes how a large mouse population with high genetic diversity will most likely be affected by a sudden, significant environmental change? All of the individuals within the population will reproduce at a higher rate, leading to a decrease in genetic diversity.
How will this change in the environment most likely affect the mouse population?
How will this change in the environment most likely affect the mouse population? The adaptation of thicker fur will be selected over thinner fur, and the population will evolve.
How did the population of brown mice become white?
Because predators could more easily spot the dark mice on light sand. The lighter mice were more likely to survive and have offspring. Natural selection favored the light mice. Over time, the population became light colored.
Is the process by which populations change over time?
Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.
Who was the reason for decreasing population of the mice?
As temperature changed across space, deer mice body mass decreased, which also aligned with the researchers' hypothesis. As precipitation increased, however, researchers expected an increase in mouse body mass due to the boost rainfall can give to foraging resources. Instead, body mass also decreased.
What would happen if the mouse population decreased?
the drop in the mouse population will lead to an increase in the beetle population. in a certain area, mice eat grass and snakes eat mice.
Are mice evolving?
Researchers tested this in two U.S. populations of house mice. They found independent evolution of a heavier body and larger nests as Eastern and Western populations invaded northern habitats after introduction from Europe. Many of the same genes changed allele frequency along with the increase in body mass.
Are mice friendly to humans?
Most wild mice are timid toward humans and other animals, but they are very social with other mice. Domestic mice are very friendly toward humans and can make good pets for older children and adults.
Can wild mice be tamed?
While it is possible to tame a wild mouse, depending on its age, wild animals, even the cute ones, should not be pets. If you find a mouse in your home, contact Skedaddle Humane Wildlife Control for mice removal in Okanagan. Do not entertain the idea of capturing the animal as a pet.
What factors might cause a change in the population?
Three primary factors account for population change, or how much a population is increasing or decreasing. These factors are birth rate, death rate, and migration.
Why do organisms change over time?
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
What is the main reason of population growth?
The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. The infant mortality rate has decreased globally, with 4.1 million infant deaths in 2017 compared to 8.8 million in 1990, according to the World Health Organization (WHO).
How will this mutation most likely affect the mouse and the population Brainly?
How will this mutation most likely affect the mouse and the population? - The mouse with the mutation will not survive, and the trait will disappear from the population. - The mouse with the mutation will survive and reproduce, and the trait will spread over future generations.
How will this mutation most likely affect the squirrel population?
A genetic mutation causes a squirrel to be born with much darker fur than its parents. How will this mutation most likely affect the squirrel population? Because the trait was caused by a mutation, it will not be passed on to any offspring, resulting in the disappearance of the trait.
What would most likely cause this species to become extinct?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago.
Which is a problem associated with the expansion of highly populated areas?
Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption are exacerbated by the increasing population density and demands of urban environments. Strong city planning will be essential in managing these and other difficulties as the world's urban areas swell.

Wolves have been a part of the island's wilderness for decades, so why relocate?
Wolf Relocation
Nineteen wolves were relocated to Isle Royale from the Great Lakes Region.
What happens when population size is reduced?
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
When individuals survive and reproduce at a higher rate than others in the same population?
When individuals survive and reproduce at a higher rate than others in the same population due to some environmental pressure
Why aren't there any dinosaurs alive?
This is purely by chance and isn't significant. The extinct dinosaur and modern bird share a common ancestor. All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today. Dinosaurs choose to fly, and evolved into birds to escape predation and capture food. Tags: Question 4.
Do we have the same amount of superbugs?
We have always had the same amount of superbugs; modern media just discusses them more.
How does adaptation respond to natural selection?
To understand adaptation in response to natural selection, students have to refocus their attention. Admittedly, this is a big job as there are several mechanisms at multiple levels: adaptation occurs at the population level while survival occurs at the organism level, and traits (which can help survival) are generated at ...
What is MLS in a deer mouse?
The ConnectedBio Multi-Level Simulation (MLS) allows students to explore how each biological level of scale contributes to the evolution of fur colors in the deer mouse.
Why do biology students talk about individual organisms?
But because they are focused at the organism level instead of the population level, they overlook the actual mechanisms for natural selection.
