Answer: True

Explanation:

Earth's south pole and the magnetic south are not the sole cause but an important element to why Earth is a magnet. "The south magnetic pole is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed vertically upwards. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field."

What processes or events might change or alter the original order of the layers?

Ierofanga [76]

Answer:

Events can occur naturally, such as earthquakes, or a hurricane, others can be caused by humans, such as oil spills or air pollution. An event can cause changes in one or more of the spheres and an event can be the effect of changes in one or more of the four spheres on Earth. This cause and effect relationship in both directions between the event and the sphere is called interaction. Interactions also occur between spheres; for example, a change in the atmosphere can cause a change in the hydrosphere and vice versa.

Interactions that occur as a result of events such as floods or forest fires impact only a local region, meaning that flood waters can only travel a limited distance from their original river, and a forest fire only burns vegetation in that area. On the other hand, the effects of events like "El Niño" or ozone depletion can cause interactions that can be observed around the world. For example, the “El Niño” event — a change in ocean currents off the coast of Peru — can cause changes in weather patterns throughout North America, while the reduction of the ozone layer over Antarctica can result in an increase in levels of ultraviolet B radiation around the world.

Explanation:

Understanding the interactions that occur in Earth's system also helps people prepare for the effects of natural disasters like volcanic eruptions. This understanding allows people to predict things like how far and in which direction the lava will flow. This relatively new field of study of interactions between events and Earth spheres is known as Earth System Science, or ESS. There are ten possible types of interactions that can occur within the earth system. Four of these interactions are between the event and each of the spheres:

-event <--> lithosphere

-event <--> hydrosphere

-event <--> biosphere

-event <--> atmosphere

1.Event <--> Hydrosphere

The lack of moisture in the ground and in the vegetation may have provided a dry environment in which the fires, once burning, continued to burn.

The heat from the fire may have further removed moisture from the air, soil, and vegetation through the evaporation process.

2.Event <--> Atmosphere

Lightning could have started the fires igniting the dry vegetation.

Gaseous pollutants such as carbon dioxide (CO2) may have been produced while vegetation was burned and blown into the air by the wind.

3.Event <--> Lithosphere

The intense heat from the fires may have caused some of the rocks to break.

4.Event <--> Biosphere

Dead branches and pine cones on the floor may have provided fuel for the fires.

The seeds of some plants may have required their outer shells to be burned before they germinated; therefore these benefited from forest fires.

A scientific model doesnt need to be something physical. It can also be a mathmatical____

Naddika [18.5K]

I would go with mathmatical formula because of physics and what not but I'm not completely sure so if you have a different possible answer you think would be better, go with that :)

alfred hershey and martha chase designed an experiment to determine the chemical makeup of griffith's transforming principle. de

MAXImum [283]

Answer:

Bacteriophages (phages) are viruses that infect only bacteria and do not infect mammalian or plant cells. Phages are ubiquitous in the environment. Phages or bacteriophages were chosen as a model system for their simplicity, as they only contained protein-coated nucleic acid. Alfred D. Hershey and Martha Chase (who were part of the bacteriophage group) in 1952 studying the infection of the bacterium Escherichia coli by the T2 phage show that the information definitely resides in the DNA. They used phage with either [32P] -labeled DNA or [35S] -labeled proteins to infect the bacteria. Immediately afterwards, they centrifuged the sample so that the infected bacteria remain in the pellet and the virus capsids (proteins) remain in the supernatant. [35S] is found in the supernatant, whereas [32P] is found in bacteria. After one cycle of infection, it was observed that when phage labeled in the [35S] proteins were used, only 1% of the radioactivity was incorporated into the progeny. But when phages were [32P] labeled, more than 30% of the radioactivity was in the progeny. They showed directly that what is transmitted from one progeny to another is the DNA and not the proteins, despite having first "diluted" in a bacterium.

Explanation:

Bacteriophages are viruses that infect bacteria in a specific way. Bacteriophages, like other known viruses, are found in an intermediate zone between living organisms and inert matter. Bacteriophages bind to the host pathogenic bacterium, introduce their genetic material, replicate inside it and destroy it. Hersey, along with his assistant Martha Chase, used phages because they knew that T2 phages were made up of 50% proteins and 50% nucleic acids and that phages entered bacteria and reproduced. As the progeny carried the same infection traits, the genetic material of this had to be transmitted to the offspring, but the mechanism was unknown. These scientists carried out an experimental work with the T2 virus, a bacteriophage that infects the bacterium Escherichia coli, which it reproduces by attaching itself to the outer wall of the bacterium, injecting its DNA into it where it replicates and directs the synthesis of the phage's own proteins. Phage DNA is encapsulated within proteins and produces phages, which lyse or disrupt the cell and release phage from progeny. They infected a culture of bacteria with radioactively labeled phages: the protein coat with sulfur (35S) and its DNA with phosphorus (32P). After infection, they separated the phages from the bacteria by violent shaking using a mixer (hence the name of the experiment). By centrifugation the much smaller phages remained in the supernatant and the much larger bacteria in the pellet. 85% of the radioactivity corresponding to DNA appeared in the pellet and 82% of the protein in the supernatant. This result supported the idea that DNA was the only component of the bacteriophage that penetrated the interior of the bacteria and, having the ability to form new phages, constituted the genetic material.
