What form of natural selection is shown on a graph as selection against an extreme?
Directional selection is shown on a graph as selection against an extreme. This occurs when individuals at one extreme of a trait distribution have lower fitness than individuals with intermediate phenotypes or those at the opposite extreme. Over time, this can lead to a shift in the average phenotype of a population.

Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
Stabilizing selection would result in a graph showing a peak at the intermediate phenotype, with fewer individuals at the extreme phenotypes. This is because individuals with intermediate phenotypes are favored, leading to the reduction of extreme phenotypes in the population over time.
Compare and contrast stabilizing directional and disruptive selection?
Stabilizing selection is where a population is favored by just the right amount of a certain trait, and if they don't have the right amount of that certain trait then they die. Example: Human babies and birth weight, if the baby is too small, i gets sick. If the baby is too big, it cannot get through the pelvis; but just the right weight and it will come out lively and well. Disruptive selection is when an animal has to fit in with its environment; I.E., camouflage.
In the composition model the two step process of composition and selection can be graphically visualized as which graph?
And-xor
What would a graph of directional selection look like?
A graph of directional selection typically shows a bell-shaped curve representing the trait distribution in a population. Over time, as one extreme of the trait becomes more favorable, the curve shifts in that direction, indicating an increase in the frequency of individuals with that trait. This shift results in a new peak in the distribution, demonstrating that the population is adapting to environmental pressures. The overall shape of the curve remains similar, but its position changes along the x-axis.
How do you make an acceleration time graph from the data of a velocity time graph?
To create an acceleration-time graph from a velocity-time graph, you need to find the slope of the velocity-time graph at each point. The slope represents the acceleration at that specific instant. Plot these acceleration values against time to get the acceleration-time graph.
Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
Stabilizing selection would result in a graph showing a peak at the intermediate phenotype, with fewer individuals at the extreme phenotypes. This is because individuals with intermediate phenotypes are favored, leading to the reduction of extreme phenotypes in the population over time.
What does disruptive selection look like on a graph?
Disruptive selection on a graph typically appears as a bimodal distribution, where two distinct peaks represent extreme phenotypes, while the intermediate phenotypes are less common or absent. This pattern indicates that individuals at both extremes of a trait are favored by natural selection, leading to a divergence in the population. The graph may show a U-shaped curve, with low frequencies of intermediate traits and higher frequencies of traits at both ends. This form of selection can promote speciation by encouraging the development of distinct traits within a population.
Why would stabilizing selection change the shape of a graph of phenotypes?
Stabilizing selection favors individuals with traits that are average or intermediate, reducing the frequency of extreme phenotypes. As a result, the distribution of phenotypes shifts towards the mean, leading to a narrower and taller bell-shaped curve on the graph. This change indicates a decrease in phenotypic variation, as the extremes are selected against, promoting a more uniform population. Over time, this stabilizing effect can enhance the fitness of the population in a stable environment.
Does this selection of counters make for an effective graph Why or why not"?
The selection of counters may or may not make for an effective graph, depending on the data being represented. If the counters accurately reflect the data and are clearly labeled, then the graph is likely to be effective. However, if the counters are unclear or do not accurately represent the data, the graph may not be effective.
How can one determine the natural frequency from a graph?
To determine the natural frequency from a graph, identify the peak point on the graph which represents the highest amplitude or resonance. The frequency corresponding to this peak point is the natural frequency of the system.
What is stabilizing evolution?
A mechanism (most common) of natural selection where overall genetic diversity decreases due to particular trait or genotype getting 'fixed' into the population. It is usually represented as a parabola on a graph.
What represents acceleration on a graph?
The answer depends on the variables in the graph! In a graph of age against mass there is nothing that represents acceleration.
Compare and contrast stabilizing directional and disruptive selection?
Stabilizing selection is where a population is favored by just the right amount of a certain trait, and if they don't have the right amount of that certain trait then they die. Example: Human babies and birth weight, if the baby is too small, i gets sick. If the baby is too big, it cannot get through the pelvis; but just the right weight and it will come out lively and well. Disruptive selection is when an animal has to fit in with its environment; I.E., camouflage.
Why is the area under the curve for the force graph equal to the impulse?
It is not, if it is a graph of force against acceleration.
Three ways natural selection picks a phenotype?
stabilizing selection: when individuals near the center of the curve have a higher fitness than individuals at either end of the cure, keeping the center at its current location but narrows the overall graph directional selection: when individuals at one end of the curve have a higher fitness than individuals at the other end, or middle, causing the entire curve to move as the character trait changes disruptive selection: when individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle, causing the single curve to be cut into two These three types of selection are brought about by natural selection, so whichever one is favored, then the genes evolve in that specific direction. natural selection acts on the genotype, but the results are seen in the phenotype
What type of graph is present between natural numbers verses their squares?
An approximation of a parabola. (It would be an exact parabola if you graph all numbers, not just natural numbers.)
The following curve shows the distribution of the masses of the individuals in a population of gerbils. Which of the curves below shows the same population after stabilizing selection has happened?
It would be the one taller then the original graph. APEX
