Prokaryotes are unicellular organisms that do not have a true nucleus. They are considered the simplest and oldest forms of life that have existed on Earth.

In order for prokaryotes to exist continuously on Earth, the following geological changes or events had to have occurred first: Heavy Bombardment must end first

Moon formation must have already occurred Free Oxygen must have come together to form an Orone layer Earth must have cooled and solidified. Let's take a look at each of these in more detail:

Heavy Bombardment must end first: Heavy Bombardment is the period in the early history of the Earth where it was constantly bombarded by meteorites and other debris from space. This period ended about 4 billion years ago. The bombardment would have made it difficult for life to exist, so it had to end before prokaryotes could evolve.

Moon formation must have already occurred: Moon formation is thought to have occurred about 4.5 billion years ago when a Mars-sized object collided with Earth. The collision would have caused significant changes to the Earth's surface, including the formation of the moon. The moon has played a role in stabilizing the Earth's rotation and providing a stable climate, which is important for the survival of prokaryotes.

Free Oxygen must have come together to form an Orone layer: Prokaryotes are thought to have evolved about 3.5 billion years ago. However, it wasn't until about 2.5 billion years ago that free oxygen began to accumulate in the atmosphere due to the evolution of photosynthesis in prokaryotes. The accumulation of oxygen eventually led to the formation of an ozone layer, which protects life on Earth from harmful UV radiation.

Earth must have cooled and solidified: Prokaryotes could not exist on a planet that is too hot or too cold. It is thought that the Earth's surface was too hot for life to exist during the first few hundred million years after it formed. However, as the Earth cooled and solidified, conditions became more favorable for life to evolve. This would have taken several hundred million years.

Eukaryotes must already be present as an energy source: Eukaryotes did not evolve until about 1.5 billion years ago. Prokaryotes were able to exist for billions of years without eukaryotes, so they are not necessary for their existence. However, eukaryotes have played an important role in the evolution of life on Earth as a source of energy through photosynthesis and as a food source for other organisms. Therefore, this statement is incorrect.

The major idea of Hubble's law is the more distant a galaxy is from us, the faster it moves away from us.

Hence, the correct answer is option 3.

Hubble's Law, formulated by astronomer Edwin Hubble in the 1920s, describes the relationship between the distance and the velocity of galaxies. The law states that the velocity at which a galaxy is moving away from us is directly proportional to its distance from us. This relationship implies that the universe is expanding, with galaxies moving away from each other as space itself expands.

Hubble's Law provides crucial evidence for the Big Bang theory, suggesting that the universe originated from a single point and has been expanding ever since. It has had a profound impact on our understanding of the cosmos and has revolutionized the field of cosmology.

The most time-consuming part of an archaeological investigation is the excavation. Surveying and analysis also require considerable time, but excavation involves physically digging and carefully documenting artifacts and structures, making it the most labor-intensive and time-consuming phase of the process.

While all stages of an archaeological investigation are important, excavation tends to be the most time-consuming. Excavation involves physically uncovering and carefully removing layers of soil and sediment to reveal artifacts, structures, and other archaeological features. This process requires meticulous documentation, including mapping the site, recording the precise location of finds, and photographing or drawing artifacts and structures.

Excavation is a labor-intensive task that requires skilled archaeologists, technicians, and often a team of workers. The process can be slow and methodical to ensure the preservation of delicate artifacts and the accurate interpretation of the site. Large excavation sites or complex archaeological contexts may require months or even years of work, depending on the scale and complexity of the project.

While surveying and analysis are also time-consuming aspects of archaeological investigations, they are typically more streamlined compared to excavation. Surveying involves locating and documenting archaeological sites and features across a broader landscape, which can involve extensive fieldwork and data collection. Analysis, on the other hand, encompasses the study and interpretation of the collected artifacts, ecofacts, and data. It involves various specialized techniques, such as artifact classification, laboratory analysis, and historical research. Although these stages require careful attention and expertise, they are often conducted in a controlled environment and can be more efficient compared to the physically demanding and site-specific nature of excavation.

Answer:

Factors which influence vegetation. There are four major factors which influence the nature and growth of vegetation. These are: climate, soils, nature of the surface, and man. Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

The political phenomena which is represented on the map is known as gerrymandering which is intended to manipulate the boundaries of (an electoral constituency) so as to favour one party or class.

Gerrymandering is the political manipulation of electoral district boundaries in representative democracies with the intent of creating an unfair advantage for a party, group, or socioeconomic class within the constituency.

The manipulation may include "cracking" (diluting the voting power of the opposing party's supporters across many districts) or "packing," which involves concentrating the opposing party's voting power in one district in order to reduce their voting power in other districts. It is also used to safeguard incumbents. According to Wayne Dawkins, politicians choose their voters rather than voters choosing their politicians.

An annular pattern follows curving layers around a centre location, and a trellis pattern follows one structure before cutting across a ridge and following another.

A stream is any body of moving surface water, from a small trickle to a powerful river. The drainage basin of a stream is the region from where the stream's water originates. Unless part of the water is able to traverse into a neighbouring drainage basin via groundwater movement, all precipitation (rain or snow) that falls within a drainage basin eventually flows into its stream.

The type of rock underlying and the structures inside that rock have a significant impact on the arrangement of tributaries within a drainage basin (folds, fractures, faults, etc.).

Answer:

Be a citizen of an extremely large territory.

Explanation:

The description of an empire is, a political unit made up of a vast expanse of territory that is under the direction of a single ruler. So there most likely wouldn't be elected leaders if there is a single ruler.

Empires are big and there is no evidence that you would be able to walk across your empire in a week

I don't think you would likely serve in the military because not all empires have a military and you only would if you want to be a warrior.

I think it is to be a citizen of an extremely large territory because for instance, in the articles I found, "As the state grows larger, the leaders decide they want more territory. They might need the extra land to grow enough food to feed a larger population; the neighboring states may appear to be getting too powerful; or maybe the leaders are simply greedy for more land."

It keeps talking about expanding territory, so I hope this is right and i hope it helps!

The scientist who discovered the mid-ocean ridge in 1953 was Marie Tharp. Marie Tharp was a geologist and oceanographer, and her work helped to revolutionize our understanding of the Earth's ocean floor.

She created the first detailed maps of the ocean floor, which showed the mid-ocean ridge, a massive underwater mountain range that runs along the bottom of the world's oceans.The mid-ocean ridge is a giant mountain range that runs through the center of the world's oceans.

It's formed by the movement of tectonic plates, which are large pieces of the Earth's crust that move and shift over time. When these plates move apart, magma rises up from the Earth's mantle and solidifies into new rock, adding to the mid-ocean ridge.Marie Tharp's discovery of the mid-ocean ridge was a major breakthrough in our understanding of the Earth's geology.

Her maps showed that the Earth's crust was not a uniform layer, but was instead made up of many different pieces that moved and shifted over time. This discovery helped to shape our modern understanding of plate tectonics and how the Earth's crust is formed and shaped over time.

Tharp's discovery was made possible by a combination of hard work, dedication, and technical skill. She spent years studying the data collected by oceanographers and cartographers, painstakingly piecing together the information to create her maps. Her work helped to transform the field of oceanography, and has inspired generations of scientists to continue exploring the mysteries of the deep sea.
