What else can I help you with?
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?
carrying capacity
How would Lamarck and Darwin have explained the a duck's webbed feet?
As a results of duck of geneticVariation in duck population. *some had webbed feet than others *as results of not having webbed feet to compete for their food *duck with unWebbed feet Died *duck with Webbed feet Survive this called Natural Selection *The characteristics of Webbed feet acquired and pass on to the subsequently generations *All duck had webbed feet
What is the average size and weight of a normal jaguar?
Males average from 150-250 pounds, females are smaller. Some jaguars are larger, especially those in the Amazon river basin.
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
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.
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.
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.
Is the population of Michigan smaller or larger than kansas's population?
larger
What are the 5 ways a population can evolve?
A population will most likely evolve when there is a small population, mutations exists, natural selection may take place, nonrandom mating occurs, and/or gene flow may occur. Sexual selection, genetic drift, Gene flow, Mutation, and natural selection are five ways a population can evolve. Sexual selection is natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. Genetic drift is variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. Gene flow is the transfer of alleles or genes from one population to another. Mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
Is the population of Japan larger then the us population?
No.
