When the hare population increased what happened to the lynx population. Why?
The Lynx population got larger because there were enough prey for all the predators.
The beaks of finches on the Galapagos Islands enlarged over generations in response to what factor?
The beaks of finches on the Galapagos Islands enlarged over generations in response to variations in food sources. Larger beaks were favored for cracking tougher seeds during periods of drought when softer seeds were scarce. This adaptation allowed finches with larger beaks to better survive and reproduce, passing on their genes for larger beaks to the next generation.
When a rabbit population cannot grow any larger it has reached its?

How Lamarck an Darwin would have explained the large eyes of an owl?
Lamarck would explain the large eyes of an owl through the idea of inheritance of acquired characteristics, suggesting that owls developed larger eyes over generations due to a need for enhanced vision in low-light conditions, and this trait was passed on to their offspring. In contrast, Darwin would attribute the large eyes to natural selection, proposing that owls with larger eyes had a better chance of survival and hunting success in dim environments, leading to the proliferation of this advantageous trait over time.

A population of mice lives near a stream. The larger mice tend to live longer and over many generations the average mouse size gets larger. What type of selection is this?
Directional selection
A poplulation of mice lives near a stream the larger mice tend to live longer and over many generations the avarge mouse size gets larger what type of selection is this?
This is an example of directional selection. In this scenario, the larger mice have a survival advantage, leading to increased reproductive success and a gradual increase in average mouse size over generations. As a result, the population evolves to favor the larger phenotype, demonstrating how environmental pressures can shape species characteristics.
Could you breed pugeons with large beaks using artificial selection?
Yes, it is possible to breed pigeons with larger beaks using artificial selection. By selectively breeding individuals with larger beaks over generations, you can potentially increase the average beak size of the population. However, it is important to consider ethical implications and welfare of the pigeons when conducting such breeding programs.
How is beak size an example of directional selection?
Beak size in a bird population that increases due to an increase in availability of large seeds is an example of directional selection. Individuals with larger beaks are better suited to crack open the larger seeds, increasing their chances of survival and reproduction. Over time, this can cause the average beak size in the population to shift towards larger sizes.
What is the definition of sample referring to the mathematical term?
A selection taken from a larger group (the "population") so that you can examine it to find out something about the larger group.
The graph above shows the frequency distribution of a population of fish before and after scientists engaged in a breeding program over many generations. explanations best describes the program?
The graph likely shows a shift towards larger fish sizes after generations of selective breeding. Scientists likely selectively bred larger fish to produce offspring with desired traits, leading to an increase in the frequency of larger fish in the population over time.
Give an example of stabilizing selection using body size of lizards?
Stabilizing selection in lizards can be observed in species where medium-sized individuals have a survival advantage over both smaller and larger lizards. For instance, smaller lizards may be more susceptible to predation due to their inability to escape effectively, while larger lizards may face challenges in thermoregulation or mobility in dense vegetation. As a result, the population tends to stabilize around an optimal body size, maximizing survival and reproductive success. This selection pressure maintains the intermediate size range over generations.
What is the average horizontal iris diameter?
The average diameter of an iris is 11.8mm, with the majority of the population falling between 10.2mm and 13.00mm, on the larger end.
What is a change in the size or frequency of a trait based competition for mate?
A change in the size or frequency of a trait-based competition for mates refers to evolutionary shifts in specific characteristics that influence reproductive success. For instance, if larger body size in males becomes more advantageous due to female preferences, the frequency of larger males may increase over generations. This change can result from natural selection, where traits that enhance mating success become more prevalent in the population. Such dynamics illustrate the interplay between sexual selection and evolutionary adaptation.
Which has a larger population Houston or Omaha?
Houston has a larger population
How does overpopulation relate to natural selection?
Natural selection is the nonrandom process by which biological traits become either more or less common in a population as a function of differemtial reproduction of their bearers. One of the main processes by which natural selection takes place is the competition over resources. The larger the population in a certain area, the more competition takes place. In the long run, it doesn't matter wheather or not the area is overpopulated; within any and every population, competition over resources takes places, so, in turn, natural selection does, too.
Which state has a larger population Michigan or Montana?
MIchigan has a larger population.
