10. Pilihan ganda45 detik1 ptQ. Dark moths began to outnumber white moths in cities after the Industrial Revolution. What is the most likely reason for this change?Pilihan jawabanLight-colored moths mutated into dark colored moths.Light-colored moths began to die due to overpopulation.Light-colored moths were less favored for survival in the new environment.Light-colored moths began to turn black because of factory pollution.
The most likely reason for dark moths beginning to outnumber white moths in cities after the Industrial Revolution is that light-colored moths were less favored for survival in the new environment.
Dark moths began to outnumber white moths in cities after the Industrial Revolution primarily because light-colored moths were less favored for survival in the new environment. The pollution and soot from factories and other industrial activities darkened the bark of trees in urban areas, providing better camouflage for dark-colored moths. This gave dark moths a survival advantage over light-colored moths, which were more visible to predators. As a result, over time, the population of dark moths increased while that of light-colored moths decreased. This phenomenon is an example of natural selection and demonstrates how human activities can have unintended consequences on the environment and the species that inhabit it.
This is because the soot and pollution from factories and other industrial activities darkened the bark of trees in urban areas, providing better camouflage for dark-colored moths. As a result, dark moths had a higher survival rate than light-colored moths, leading to an increase in their population over time. The other options listed are not supported by scientific evidence and are therefore less likely to be the cause of the change in moth populations.

select all of the following that explain why the fossil record is incomplete. - erosion and movements of the earth's surface have destroyed many fossils that did form. - many organisms decomposed before they were buried in sediments - many fossils may never be discovered because they are buried deeply or submerged under water.
For a number of causes, the fossil record is incomplete. Many fossils that did form have been lost by erosion and shifting of the earth's surface, and many more may never be discovered because they are buried underground or submerged beneath water.
In addition, many species died before being buried in sediments, which prevented them from becoming fossils.
Furthermore, the fossil record only provides a snapshot of ancient life; it's possible that certain species existed before and after fossilisation episodes but were not preserved as a result.
Finally, living organisms are continually developing, and many species may have evolved and become extinct before they could be fossilised. The fossil record is imperfect for the reasons listed above, among others.

subduction zones occur a what type of plate boundary?
Subduction zones occur at convergent plate boundaries, where two tectonic plates move towards other and one plate sinks beneath.
The sinking plate, known as the subducting plate, sinks into the Earth's mantle and begins to melt, producing magma. This magma rises and can form volcanoes along the edge of the overlying plate, creating a chain of volcanic islands such as the Aleutian Islands or the Japanese island arc.The subduction process also generates earthquakes, as the subducting plate grinds against the overriding plate and releases built-up stress. The boundary between the two plates is known as the Benioff Zone, and it is characterized by a series of shallow and deep earthquakes that occur at depths of around 70 km to 700 km.Subduction zones are found along the margins of continents, where oceanic plates collide with and sink beneath continental plates. Some examples of subduction zones include the Pacific Ring of Fire, the Andes Mountains of South America, and the Sumatra-Java trench in the Indian Ocean.

What is the tenacity of a mineral, and how can it be described? Tenacity is the mineral's resistance to breaking, bending, or otherwise deforming.
Tenacity refers to a mineral's ability to resist breaking, bending, or otherwise deforming.
In other words, it describes how tough and resilient a mineral is under stress. There are several different terms that can be used to describe a mineral's tenacity, including brittle, malleable, ductile, sectile, and flexible.
Brittle minerals are those that break or shatter easily when subjected to stress, while malleable minerals can be bent or molded without breaking. Ductile minerals can be stretched or pulled into thin wires or sheets, while sectile minerals can be cut into thin slices with a knife.
Flexible minerals can be bent or twisted without breaking, but they will not retain their new shape once the stress is removed. Understanding a mineral's tenacity is important for identifying and classifying minerals, as well as for predicting their behavior under various geological conditions.

what kind of tides would you expect during a new moon?
When the sun, moon, and Earth are in alignment (at the new or full moon), the solar tide adds to the lunar tide, resulting in extra-high high tides and very low, low tides—both known as spring tides.
There are three basic tidal patterns in the world: semidiurnal, mixed, and diurnal. A semidiurnal tide occurs when both high tides are roughly equal to each other and both low tides are roughly equal. A mixed tide occurs when the two highs and lows differ significantly.
This is the most common tidal pattern, with two highs and two lows each day and little variation in the height of successive high or low waters, and it is found along much of North America's east coast.

The Earth and planets provided a comprehensive explanation for a wide range of celestial phenomena, from the stars and planets to the phases of the Moon and the retrograde motion of the planets.
Copernicus believed that the rotation of the Earth on its axis was responsible for the daily motions of the stars and planets in the sky. As the Earth rotates, it appears as though the stars and planets are moving across the sky, but in reality, it is the Earth's rotation that is causing this apparent motion.
However, Copernicus' theory also explained other celestial phenomena, such as the phases of the Moon. He observed that the Moon appeared to go through a series of phases, from new to full and back to new again, and he explained this as being caused by the Moon's position relative to the Earth and Sun.
Additionally, Copernicus' theory accounted for the retrograde motion of the planets, which was a puzzling phenomenon to earlier astronomers. As the planets move in their orbits around the Sun, they occasionally appear to reverse their motion and move backwards for a time. Copernicus explained this as being caused by the relative motion of the Earth and the other planets, and the fact that the Earth moves faster in its orbit than the outer planets.

What role does nondisjunction play in the formation of a fertile allopolyploid hybrid? -It doubles the chromosome number in the hybrid.
-It allows gametes of the two parent species to combine.
-It causes the chromosomes to line up at the center of the cell during mitosis.
-It breaks down chromosomes that don't exist as homologous pairs.
Nondisjunction plays a role in the formation of a fertile allopolyploid hybrid by doubling the chromosome number in the hybrid.
Nondisjunction is an error in cell division that occurs when chromosomes do not separate properly during meiosis, leading to gametes with an abnormal number of chromosomes. In the context of allopolyploid hybridization, nondisjunction can occur when gametes from the two parent species with different chromosome numbers combine, resulting in a hybrid with a doubled chromosome number. This can lead to the formation of a fertile allopolyploid hybrid, as the doubled chromosome number can result in hybrid offspring with new combinations of traits and an increased level of genetic diversity.
Allopolyploidy is a type of hybridization where two different species mate and produce offspring with a doubled set of chromosomes. This is because the hybrid offspring inherit one set of chromosomes from each parent, resulting in a chromosome number that is twice that of the parent species.
In order for an allopolyploid hybrid to be fertile and capable of producing viable offspring, it is important that the chromosomes from the two parent species are able to pair and align properly during meiosis. This is where nondisjunction comes into play. Nondisjunction is a type of meiotic error where the chromosomes do not separate properly, resulting in gametes with an abnormal number of chromosomes.

5. based upon your calculations, can the landscape be restored to its original topography? explain why this is or is not possible. does legislation requiring restoration make mining more expensive?
Yes, legislation requiring restoration can make mining more expensive. Restoring a landscape after mining activities have taken place can be a costly and time-consuming process, and mining companies may need to allocate additional funds and resources to comply with restoration requirements.
Restoring a landscape to its original topography after mining activities have taken place is often difficult, if not impossible. The mining process typically involves significant disruption of the natural landscape, including excavation, removal of vegetation and topsoil, and alteration of the underlying geology. As a result, it can be challenging to recreate the original topography and ecosystem.
In some cases, however, it may be possible to mitigate some of the damage and restore some aspects of the landscape. This might involve techniques such as contouring the land to mimic natural topography, reintroducing native vegetation, and implementing erosion control measures. The success of restoration efforts will depend on a range of factors, including the extent and type of mining activity, the condition of the landscape prior to mining, and the resources available for restoration.
Legislation requiring restoration can make mining more expensive, as companies may need to allocate additional funds and resources to comply with restoration requirements. This can also be a deterrent for mining companies, as the cost of restoration can make certain mining activities economically unfeasible. However, requiring restoration can also help to minimize the environmental impact of mining and ensure that the land is returned to a more sustainable state after mining is complete.

during the process of adiabatic cooling, the temperature decreases as air expands, but during adiabataic warming the temperature increases because the air has:
During the process of adiabatic cooling, the temperature decreases as air expands because the expansion of the air causes it to do work on its surroundings, which in turn lowers its internal energy, resulting in a decrease in temperature.
Adiabatic heating and cooling are thermodynamic processes that occur without the exchange of heat or matter between the system and its surroundings. These processes occur as a result of changes in the internal energy of the system caused by work done on or by the system.
During adiabatic heating, a gas is compressed, which increases its pressure and temperature. The work done on the gas during compression is converted into an increase in the internal energy of the gas, resulting in a higher temperature. This increase in temperature is due to the gas molecules having a higher average kinetic energy and moving faster.
On the other hand, during adiabatic cooling, a gas is allowed to expand, which reduces its pressure and temperature. The work done by the gas during expansion decreases its internal energy, resulting in a lower temperature. This decrease in temperature is due to the gas molecules having a lower average kinetic energy and moving slower.
