which intermolecular force arises from temporary, instantaneous diploes?

Answers

The intermolecular force arises from temporary, instantaneous diploes is called London Dispersion Force (LDF).

London Dispersion Force or van der Waals force is a weak attractive force between all types of atoms and molecules. It is caused by the temporary alignment of electrons in the outermost shell of an atom or molecule, which creates a temporary dipole. These temporary dipoles can interact with each other, resulting in a weak attractive force. The strength of London Dispersion Force is dependent on the electron distribution and polarizability of the atoms or molecules and it becomes stronger as the size of the molecule increases and the number of electrons increases.

It is the weakest of the intermolecular forces but it is the only one that acts between all types of atoms and molecules.

Answers

The Law of Original Horizontality is the aw makes you expect to find stratum D in sector 3.

The reason why there is no stratum D in sector 3 might be because of natural earth changes like geological events.

What is the Law of Original Horizontality

The Law of Original Horizontality is a basic rule in geology that says sedimentary rock layers are first put down in flat or mostly flat layers. This rule assists geologists in determining how rocks are placed in relation to one another in a geological formation.

So, If the rule that says rock layers are usually formed in flat, horizontal layers applies to this specific place we are studying, it means that layer D should be here in sector 3.

Phases of mitosisThe majority of the cell's life is spent in the interphase, just before prophase, where mitosis's start-up is prepared for (the DNA is copied). The prophase is technically the first phase of this process, though, because the actual process requires the division of the nucleus. The duplicated chromosomes are aligned, separated, and transferred to the cell's opposite poles during the multistep mitotic phase, after which the cell divides into two brand-new, identical daughter cells.The cell divides its cytoplasm and divides its DNA into two sets during the mitotic (M) phase to produce two new cells.

The greatest decline on record in the Moose population occurred in 1996, in 1997 was the limiting factor that probably caused declintons the dependent or a density independent, what was the limiting factor.
explain

Answers

The greatest decline on record in the Moose population occurred in 1996-1997, and the limiting factor that probably caused the decline was density-dependent, specifically winter tick infestation.

winter tick infestation is a classic example of a density-dependent factor that can cause significant harm to Moose populations. A high density of moose populations can lead to a higher probability of infestation and greater negative impacts on individual moose health.

In the case of the Moose population decline in 1996-1997, the winter tick infestation was likely the main limiting factor responsible for the decline. The tick population can increase rapidly when moose densities are high, leading to a higher probability of infestation and greater negative impacts on individual moose health. This is further supported by the fact that the Moose population in other regions, with lower densities, did not experience the same level of decline.

Therefore, the limiting factor that caused the decline in Moose population in 1996-1997 was likely density-dependent, specifically the winter tick infestation.

how did nepa revolutionize environmental protection in the united states

Answers

Answer: The National Environmental Policy Act (NEPA) was signed into law by President Nixon in 1970 and it revolutionized environmental protection in the United States by establishing a comprehensive national policy for the protection of the environment.

NEPA requires federal agencies to consider the environmental impacts of their actions and to provide an assessment of those impacts to the public. This process is known as an Environmental Impact Statement (EIS). The EIS requires agencies to analyze the environmental effects of proposed actions, alternatives to those actions, and the impacts of no action.

This act also established the Council on Environmental Quality (CEQ) to oversee the implementation of NEPA and to provide guidance to federal agencies on how to conduct the EIS process.

NEPA has played a critical role in protecting the environment by requiring federal agencies to consider the environmental impacts of their actions and to involve the public in decision-making. It has also helped to prevent or mitigate the negative impacts of federal actions on the environment.

The law also provided a framework for a robust public participation process in which citizens, organizations and tribes can raise concerns and provide input on proposed federal actions that may impact their environment.

In summary, NEPA revolutionized environmental protection in the United States by establishing a comprehensive national policy for the protection of the environment, requiring federal agencies to consider the environmental impacts of their actions, involving the public in decision-making and provided a framework for a robust public participation process.

Rainforests are habitats for many plants and animals. However, habitat fragmentation is occurring because of human activity. When a rainforest is fragmented, a large area is divided into small patches that are isolated from each other. Species living in these patches are more likely to become extinct as a result of overcrowding and competition.

Which of the following is the best way to minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem?
A.
constructing boundaries and fences around each habitat patch
B.
building natural green pathways across the original habitat to join all the patches together
C.
building concrete roads across the original habitat to join all of the patches together
D.

Calculate the population density of 900 sheep in a plot of land that is 3.00 km by 2.00km

Answers

The population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.

The population density of 900 sheep in a plot of land that is 3.00 km by 2.00 km can be calculated by dividing the total number of sheep by the area of the land.

First, we need to calculate the area of the land. The area can be found by multiplying the length and width of the plot of land:

Area = length × width = 3.00 km × 2.00 km = 6.00 km²

Next, we divide the total number of sheep by the area to calculate the population density:

Population Density = Total number of sheep / Area = 900 sheep / 6.00 km²

Performing the calculation, we find:

Population Density = 150 sheep/km²

Therefore, the population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.

Population density is a measure of the number of individuals (in this case, sheep) per unit area. By dividing the total number of sheep by the area of the land, we obtain the population density in terms of sheep per square kilometer. In this case, the population density is 150 sheep/km², indicating that there are, on average, 150 sheep within each square kilometer of the land.

What is the thickest layer of the Earth and how thick is it?

The thickest layer of the Earth is the mantle, the Earth is divided into four main layers: the crust, mantle, outer core, and inner core. The Earth mantle is about 1,802 miles thick, making up 84% of Earth's total volume.

The mantle is the most solid bulk layer of the Earth's interior because it is found between the core (the layer that have the highest temperature) and the crust (superficial layer), being the form of that layer between rock solid (upper mantle) to almost liquid (lower mantle), since the temperature, pressure, and molecules (iron and niclel) are why the layer is solid bulk.

[6 marks

Answers

Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These  characteristics are passed on to their offspring.

According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.

Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.
