To determine how allele frequency changes
The equation to calculate the work done is: Work done (J) = force applied (n) x distance moved of force (m)
Forces only do work if they move things. You could push on a brick wall all day but you would still not do any work. If you stand still, your feet are pushing on the ground, but you are not doing any work, You could be asleep. So, forces only do work if they move and actually do something. In cases where you might say that only half of a force did work, then it's best to say that you have two forces. One that did work and one that did nothng. In cases where a force has only done half the work, then you would have to wait for that force to finish the other half, or get a new force.
The equation for work is: work = force x displacement or W = Fd Since the car isn't moving, it has a displacement of zero. This therefore means that even though the force applied by the person on the car may be extremely large, the work done will be equal to zero. For example, if the person exerts a force of 15000 N, the equation will look like this: W = Fd W = (15000 N) x (0 m) W = 0 J
Joule is a measure of energy, also called work, and it doesn't matter what type of energy it is. Work is normally used to describe mechanical energy but it is still measured in Joules.
Conductors of electricity are usually metals although there are a few cases where non metals are conductors as well such as graphite and types of salt solutions, hope this answers your question.
To work out Hardy-Weinberg problems, you need to first identify the frequencies of the alleles in a population. Then, you can use the Hardy-Weinberg equation (p^2 + 2pq + q^2 = 1) to calculate the frequencies of genotypes and phenotypes in the population. Remember that p represents the frequency of one allele and q represents the frequency of the other allele in the population.
To effectively practice Hardy-Weinberg problems and improve your understanding of population genetics, you can start by familiarizing yourself with the Hardy-Weinberg equation and its assumptions. Then, work through practice problems that involve calculating allele frequencies, genotype frequencies, and determining if a population is in Hardy-Weinberg equilibrium. Additionally, try to understand the factors that can disrupt Hardy-Weinberg equilibrium, such as genetic drift, natural selection, and gene flow. Regular practice and reviewing your answers will help reinforce your understanding of population genetics concepts.

Mutations introduce new genetic variation into a population, which can disrupt the balance of allele frequencies required for the Hardy-Weinberg equilibrium. If a mutation increases the frequency of a particular allele, it can lead to deviations from the expected genotype frequencies under the Hardy-Weinberg equilibrium.
The Hardy-Weinberg principle provides a mathematical model to predict genotype frequencies in a population that is not evolving. If genotype frequencies in a population do not match the predicted frequencies, then evolution (such as genetic drift, natural selection, or gene flow) is likely occurring.
To effectively practice Hardy-Weinberg problems, you can start by understanding the basic principles of the Hardy-Weinberg equilibrium. Then, work on solving various practice problems to improve your understanding and accuracy in providing answers. Make sure to review your answers and seek feedback to identify any mistakes and areas for improvement. Practice regularly to reinforce your understanding and enhance your problem-solving skills.
Allele frequency is stable
Hardy-Weinberg equilibrium is a principle stating that allele frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences like mutation, natural selection, genetic drift, or gene flow. It serves as a null model against which population genetics data can be compared to detect evolutionary forces at work. Deviations from Hardy-Weinberg equilibrium can indicate that evolutionary processes are influencing the population.
Here are a few examples of Hardy-Weinberg practice problems for you to try: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? If the frequency of the recessive allele in a population is 0.2, what percentage of the population is expected to be carriers of the recessive trait? These problems can help you practice applying the Hardy-Weinberg equilibrium to calculate allele and genotype frequencies in a population.
Here are a few practice problems to help you understand Hardy-Weinberg equilibrium: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? In a population of 1000 individuals, 64 exhibit the dominant trait for a certain gene. What are the expected frequencies of the three genotypes (homozygous dominant, heterozygous, homozygous recessive) in the population? Try solving these problems using the Hardy-Weinberg equations and principles!
The distribution of alleles does not change from one generation to the next
What all the ideal non-real conditions of the Hardy-Weinberg equilibrium predict; no evolution takes place. Mating is assortative, non-random in the real world and sexual selection is at work when assortative mating takes place, thus evolution.
