What happened to the peppered moth population by 1900?

Answers

Answer 1

Around English cities in the 1900s, up to 98% of the moths were dark rather than peppered. The cause of this event piqued the interest of scientists. Early in the nineteenth century, bright types constituted the bulk of the moths gathered.

They didn't become extinct; rather, it simply decreased in frequency in urban areas. However, it continued to be the typical form in rural areas. Then, as clean air regulations took effect starting in the 1960s, the speckled "typica" form had a rebirth.

The number of dark-colored moths quickly grew. The proportion of dark-colored moths in Manchester was recorded to be 98% in 1895, a drastic change (of over 100%) from the initial frequency. By the middle of the 19th century, the number of dark-colored moths had noticeably increased.

how did rosie the riveter exemplify the cultural constraints placed on american working women during world war ii?

Answers

Rosie the Riveter was a cultural icon during World War II that represented the millions of women who entered the workforce to support the war effort. While these women played a critical role in the war, they faced significant cultural constraints and discrimination as they entered traditionally male-dominated industries.

One way in which Rosie the Riveter exemplified these cultural constraints was through her portrayal as a temporary worker, who would return to her traditional roles as a homemaker and caregiver once the war ended. The government and many employers encouraged women to work in the war industry, but they also emphasized that this work was a patriotic duty that would only last for the duration of the war.

wilderness wasnât a handicap for americans because of their advantages. (True or False)

Answers

Wilderness wasn't a handicap for Americans because of their advantages. The following statement is False.

Despite these advantages, the wilderness posed a tremendous obstacle for early American immigrants. European settlers encountered many difficulties, including disease, severe weather, and confrontation with Native American groups, in the vast and unexplored wilderness of North America. To survive in this new environment, the settlers had to adapt to new ways of life and learn new survival techniques. Even while early Americans may have had advantages like easy access to resources or technological advancements, the wilderness was still a problem.

There existed a sizable, largely unknown wilderness in America. Having no trails, roads, or other infrastructure made it challenging for settlers to navigate the landscape. In addition, there were little supplies and frequent shortages of needs like food and medicine. In addition, wolves and bears posed a menace to anybody who ventured into the forest.

The architect Domenico Fontana made the initial discovery of Pompeii's ruins in the latter half of the 16th century. After Herculaneum was found in 1709, formal excavation there started in 1738.

Southeast of Naples, in southern Italy, is the ancient city of Pompeii. Pompeii, which was established in the sixth century BC by Oscan-speaking ancestors of Campania's Neolithic people, was later influenced by the Greeks and the Etruscans before being taken over by the Samnites, an Italic tribe, in the late fifth century BC. By 80 BC, the city had become a Roman ally and was settled. When Mount Vesuvius erupted in AD 79, it completely destroyed after being devastated by an earthquake in AD 63. The village was buried by volcanic material, which kept the ruins safe for many years. Pompeii's excavation did not start until 1748, and in 1763, an inscription was discovered identifying the location as Pompeii. The beginning of the modern science of archaeology was the work done in these towns in the middle of the 18th century.

Amedeo Maiuri, who oversaw the excavations from 1924 to 1961, started serious excavation in 1951 after a pause brought on by World War II. Large regions in Regions I and II south of the Via dell'Abbondanza were revealed and the trash piled outside the city walls was removed. The Porta di Nocera and a long cemetery that lined the road heading from the gate to Nuceria were then visible. About two-thirds of the city had been discovered by the 1990s.

Answers

In the Classical period, the Greek sculptors would try to do their work by breaking off the shackles of convention and achieve what no one else had ever before attempted. They have also created life-size and life-like sculptures which glorified the human and especially male form.

What do you understand by the term classical period?

The Classical period can be understood as the period which falls between the Baroque and the Romantic periods. The music of Classical period is lighter, clearer texture than Baroque music, and it has a more sophisticated use of form. The music is homophonic and uses it a clear melody line over a subordinate chordal accompaniment, although counterpoint was by no means forgotten, especially in liturgical vocal music and, later in the period, secular instrumental music.

The music thus makes use of style galant which emphasized light elegance in place of the Baroque's dignified seriousness and impressive grandeur.

from the timing of lunar eclipses, the ancient greeks were able to

Answers

Since the time of lunar eclipses, the ancient Greeks have been able to propose a model of the solar system.

The astronomy works of the ancient Greeks based on lunar eclipses

The Greek astronomer Claudius Ptolemy proposed a geocentric model of the solar system, which was accepted as a model in the Western world and Arab countries for more than 1,300 years.

Ptolemy set out to find a solution so that the geocentric system could be compatible with all observations of lunar eclipses.

In the Ptolemaic system, the Earth is the center of the universe and the Moon, the Sun, the planets and the stars are fixed in glass spheres that revolve around it.

To explain the different movement of the planets, Ptolemy devised a particular system in which the Earth was not in the exact center and the planets revolved in an epicycle around a point located on the circumference of their main orbit or sphere.

Other important studies of ancient greeks based on lunar eclipses were the composition of the earth, the compilation of the first catalog of stars, the development of a classification system of the magnitudes of stellar brightness based on the apparent luminosity of the different stars, the determination of the Saros cycle for the prediction of solar and lunar eclipses, among many others.
