To answer this question, you will read two articles. First, read Article 1.

Planning for the construction of O'Hare International Airport began in 1945 when a committee chose Orchard Field as the location of the future airport. In 1955, the airport opened to commercial air traffic and O'Hare International Airport served as a hub for travelers throughout the world.

To respond to the increasing number of passengers, the airport expanded. O'Hare added a fifth runway and opened a terminal for international travel. Passengers could take flights to other countries and throughout the United States. The amount of land used by the airport grew to about 7,200 acres. This expansion included airplane hangars, cargo buildings, and even a post office. Next, there was an expressway built to connect O'Hare International Airport with downtown Chicago. People could travel to and from the airport quickly and easily, making it a desirable location. Finally, the main terminal building and parking lot were completed. These expansions led to a greater number of passengers. In 1962, 10 million passengers traveled through the airport that year alone. O'Hare was officially the world's busiest airport.

O'Hare's growth was accompanied by innovation. In order to increase efficiency, the airport developed a task force that allowed three runways to be used at the same time in 1976. The Passenger Facility Charge, which charged passengers for using the airport, was introduced in 1990. This money was used to improve and modernize the airport. The Airport Transit System was created to help transport passengers between terminals in 1993. In 1996, the O'Hare Noise Compatibility Commission was created to help surrounding neighborhoods deal with aircraft noise. To aid with the O'Hare Modernization Program, a Sustainable Design Manual was created in 2003. This cutting-edge document helped the airport think about the environment during the modernization process. The principles outlined in the manual were later used in a similar document in August 2009 that promoted environmental sustainability at the airport. Over the years, O'Hare International Airport has grown and innovated to manage its expansion.

Read Article 2 and answer the question.

Between O'Hare and Midway International Airports, over one thousand flights depart Chicago every day. When planes take off and land, they create vibrations. These vibrations create noise in Chicago neighborhoods. In the early days of both airports, the city of Chicago realized that aircraft noise was a problem. People were unable to talk on their phones, watch television, or sleep peacefully at night.

In 1996, the O'Hare and Midway Noise Compatibility Commissions were created to help solve the noise problem. The Commissions searched for ways to reduce the effect of aircraft noise on the surrounding neighborhoods. First, pilots and air controllers volunteered to follow the Fly Quiet Program. The program suggested that pilots use runways and flight paths over forests, highways, and industrial areas at night. By avoiding housing areas, pilots and air controllers decreased the noise level of the airplanes in these areas. That way, people would be able to sleep.

Next, the commissions focused on using sound insulation in homes near the airports. If residents lived in an area that experienced a high volume of noise, then they were eligible to have their homes insulated. Residents were given different options. Their homes could be insulated by installing special windows, doors, or air conditioning. Similar steps were also taken to insulate private and public schools in the affected areas.

The continued presence of the O'Hare and Midway Noise Compatibility Commissions is evident today. An Airport Noise Management System uses noise monitors to measure the noise levels in neighborhoods each day. A Community Outreach Vehicle distributes information about aircraft noise. Residents can use the Flight Tracker program. This online program shows images of where planes fly. If there is still a problem with noise, people can call the hotline or complete an online form.

How is the structure of Article 1 different from the structure of Article 2?

Article 1 uses cause and effect to show the impact of the airport's expansion, while Article 2 uses chronological order to show the steps taken to reduce noise over time.
Article 1 uses comparison and contrast to describe the airport in the past and present, while Article 2 uses cause and effect to show how aircraft noise angered the surrounding neighborhoods.
Article 1 uses chronological order to show the events that led to the present airport, while Article 2 uses a problem and solution text structure to show how noise is reduced in neighborhoods around the airports.
Article 1 uses problem and solution to show the issues faced by the growing airport, while Article 2 uses comparison and contrast to show the difference insulation makes.

Rocks expand and contract when they are heated and cooled which cause them to break. Physical weathering is experienced to the crust of earth. The last state of physical weathering is sand. Rocks that have some cracks are undergoing frost wedging.

Weathering is a geographical process of deterioration of rocks and minerals into parts and eventually into dust and sand. Thermal stress, a phenomenon caused by temperature variations, can also contribute to mechanical weathering.

The expansion and contraction of rock is influenced by temperature changes. The rock's structure deteriorates as this occurs repeatedly. Physical weathering and mechanical weathering disintegrates rocks without any chemical changes and  it happens to the earth's crust.

Erosion of rocks eventually results in formation of sand. Frost wedging is a process by which ice erodes the rocks having cracks. It is also called ice wedging.

Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.

Explanation:

Pure Substances:

There are two categories of pure substances: elements and compounds (In our case, we have a compound).

Element (e.g. the blue circles or the red squares):

Compound (e.g. the blue circles bonded together with the red squares in the middle picture):

Mixtures:

There are two categories of mixtures: homo- and hetero- genous.

Homogenous mixture:

Heterogenous mixture:

The second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.

The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.

The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.

Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.

The first image is correct, the image depicts a pure substance.

Answer:

The neutron was the last of the atomic components to be discovered because it does not have an electric charge, making it difficult to detect. It was also not predicted by early atomic theories, leading scientists to believe that the atomic nucleus was composed solely of protons. The discovery of the neutron required the development of new experimental techniques, such as neutron scattering, to detect its presence.

Answer:

The compound is ionic

The compound has a high melting point

The compound will conduct electricity in aqueous solution

The compound will be soluble in water

Explanation:

Now, let us consider the nature of the compound formed when a metal X looses two electrons and a non metal Y accepts one electron.

The compound formed must be ionic in nature with a  formula XY2. Ionic compounds are formed by transfer of electrons from metals to nonmetals.

The ionic substance formed is always soluble in water with a high melting point. Usually, ionic solids do not conduct electricity in the solid state because the charge carriers (ions) are tightly bound in the crystal structure while in the solid state. In aqueous solution, the ions are relatively free hence ionic substances conduct electricity in aqueous solution.

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

The period of time when sexual intercourse takes place between two organisms is called mating. However, all the matings need not end in fertilization.

The gestation period is a time when the embryo develops completely into a fetus. This is usually from the time of fertilization to the time of giving birth.

Let us take the comparison of the gestation period of 3 mammals.

The gestation period of a cow varies from 279- 287 days. The mating between the bull and cow occurs during the heat or oestrus period of the cow. At that time the bull mounts on the cow or vice-versa may happen during the mating period. This is termed bulling.

In the case of horses, the gestation period is 320-380days. The mating ritual in a horse is a bit different than in a cow. It usually has three phases of sexual behavior which includes: courtship, mating, and post mating behavior. During courtship, the stallion which is the male horse will approach the mare, prance, sniff her, nuzzle her, and groom her. The mare which is the female horse may squeal, kick, or move away to show the stallion that she is not ready. When the mare is receptive to breeding, she may stand still, deviate her tail, and urinate, leading the stallion to mount her. It usually breeds well in pastures than in controlled environmental breeding conditions.

Whereas in camels, the gestation period is far longer than in cows and horses. It is about 360-440days. The male camel displays its organ called a dulla to show out is ready for mating. The male camel Urinates on its own tail and swishes it over its back so that the Urine contains female-attracting pheromones. It shows distinct violent behavior towards other male camels. The female camel undergoes an estrous cycle in the breeding season which lasts receptive for 3-4 days, and non-receptive following the other 10 days. In the receptive period, the camel sits down and exposes its genitalia for the male camel to copulate. The whole mating takes about 20 minutes and is accompanied by gurgling and frothing by the male and bleating by the females.

It should be noted that African elephants have longer gestation periods like Asian elephants whereas no other animal has a longer gestation period than an elephant or a shorter gestation period than mice.

Answer: The wave interaction described in the scenario is known as constructive interference.

Explanation:

Constructive interference occurs when two waves meet and combine in such a way that their amplitudes add up, resulting in a larger wave. In this case, Max's steady pattern of jumping creates small waves on the trampoline, with a certain amplitude.

When Jimmy starts jumping on the trampoline, his waves combine with Max's waves. If the peaks and troughs of both waves align perfectly, they will add up, resulting in a wave with a larger amplitude. This alignment of peaks and troughs leads to constructive interference, causing Max to go twice as high without any additional effort.

The reason behind this phenomenon lies in the nature of waves. When waves meet, their amplitudes can either add up or cancel out, depending on their relative positions. In the case of constructive interference, the peaks of one wave align with the peaks of the other wave, and the troughs align with the troughs, resulting in an increased amplitude. Conversely, in destructive interference, the peaks align with the troughs, leading to a cancellation or reduction in amplitude.

So, in the scenario, Jimmy's waves align with Max's waves in such a way that their amplitudes combine constructively, resulting in Max going twice as high on the trampoline without exerting any extra effort.
