What is meant by population Demography?In genetics, a population is frequently described as a group of organisms where any two individuals can breed with one another. Because of their ability to routinely exchange gametes and produce typically viable offspring, this breeding group is often referred to as a geodome.
This means that each individual is a member of the same species. The geodome is referred to as panmictic when all gene alleles are distributed uniformly by the gametes inside it and the geodome is very vast (theoretically approaching infinity).
As demonstrated by Sir Ronald Fisher in his development of quantitative genetics, under this condition, allele (gamete) frequencies can be translated to genotype (zygote) frequencies by expanding an appropriate quadratic equation.

seismologists reporting in the journal nature geoscience this week that the earth's core may now be in the process of doing what?
We can learn about the layers that make up the Earth by understanding how waves behave as they pass through various materials. According to seismic waves, the Earth's interior is made up of a number of concentric shells, including a solid inner core, etc.
What are seismologists?
Seismologists who conduct research investigate the Earth's interior to identify variables that influence or predict earthquakes. They either present their findings at academic conferences or publish them in peer-reviewed journals, or they do both. Seismologists study earthquakes by using seismometers and examining the damage caused by them. A seismometer is a device that detects the trembling of the Earth's surface caused by seismic waves. In most cases, the combination seismometer and recording devices is referred to as a seismograph. The research of the Interior of the earth through the detection of vibrations on its surface is known as seismology. A seismologist is someone who does this type of work.

The term and concept of seafloor spreading was developed by ?
The term and concept of seafloor spreading was developed by Harry Hess in the 1960s.
What is the concept of seafloor spreading?The concept of seafloor spreading is the idea that new oceanic crust is created at mid-ocean ridges and moves away from the ridge in both directions. This process is driven by convection currents in the mantle which cause magma to rise and cool along the ridge, forming new crust. As this process continues, the older crust is pushed away from the ridge and further from the centre of the ocean. This theory of seafloor spreading is a key part of the Plate Tectonics Theory which explains how the Earth's lithosphere is formed and moves.
Why is seafloor spreading important?Seafloor spreading is important because it explains how the lithospheric plates move, allowing for the movement of the continents over time. This process also helps to explain how mountains, ocean trenches, and other features of the Earth's surface are formed. Seafloor spreading is also important because it helps to explain the formation of Earth's ocean basins, as well as the distribution of ocean life. Additionally, seafloor spreading helps to explain how Earth's climate has changed over time due to the movement of continents and the creation of new ocean basins.

d.two plates are moving apart from each other.
Answer is d. two plates are moving apart from each other.
Where would the most recently formed crust be found?The most recently formed crust would be found on the surface of the Earth, specifically in the oceanic lithosphere. Oceanic crust is formed at divergent plate boundaries, which are also known as mid-ocean ridges. Here, molten magma rises from the mantle and cools, forming new oceanic crust. The oldest oceanic crust is thought to be around 200 million years old, while the youngest is only a few years old in some places. The oceanic crust is continually recycled through the process of subduction, where it is pushed beneath another plate and melts back into the mantle.

California has been plagued with earthquakes due to its location on the Ring of Fire. The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
The Ring of Fire is caused by plate tectonics: the Pacific plate is moving northwest, scraping horizontally past the North American plate, forming a divergent plate boundary. As this movement occurs, the Pacific Plate and the North American Plate are meeting at a convergent plate boundary, where the Pacific plate is being forced below the North American plate, creating a subduction zone. This interaction between the two plates is what causes the earthquakes in California.
