When it comes to population evolution and genetics, we cannot fail to cite the Hardy-Weinberg principle which emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a particular population, the frequencies genotypic proportions will remain constant.

The five requirements for a population to be in Hardy-Weinberg equilibrium are:

Large-scale breeding population: For a population to be in Hardy-Weinberg equilibrium, it is important that this population is large, as small populations favor genetic drift (unanticipated fluctuations in allele frequencies from one generation to another).
Random mating: In order for the Hardy-Weinberg equilibrium to occur, it is necessary that the mating occur at random, with no preference for certain groups within the population. In this case, we say that the population is in panmixia, that is, they all mate at random.
No mutations: Mutations alter the total alleles present in a population (gene pool). Therefore, in a Hardy-Weinberg equilibrium population, no mutations should occur.
No gene flow: When there is gene flow due to migration or immigration of individuals, some genes may be included or excluded from the population. Thus, in an equilibrium situation, no gene flow occurs.
Lack of natural selection: For a population to be in Hardy-Weinberg equilibrium, natural selection must not be acting on it. If natural selection acts, some genotypes will be selected, modifying the allelic frequencies of the population.

Which of the following best describes the function of fruits? Group of answer choices

ratelena [41]

The correct answer is B. Protection and dispersal of seeds

Explanation:

In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.

Know what makes a solution acidic or basic (the pH number and the ions).

Brrunno [24]

To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.

In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.

In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content. According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
In basic solutions, the concentration of OH- ions is higher than that of H3O + ions. If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution. Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.

How does the polio vaccine work

DerKrebs [107]

Polio affects the central nervous system and spinal cord. It can cause muscle weakness and paralysis. Polio is a life threatening condition because it can paralyze the muscles that help you breathe.

The polio vaccine is used to help prevent these diseases in children and adults.

Some cities hang their traffic

Jlenok [28]

Answer:

The angle and location

Explanation:

There are some who can't perceive the order of red and green together. Having it angled up and down is safer because you know out of common sense that red is on top and green is on the bottom. Having it sideways makes the light elevated on the same level, deceiving the eye better.
