This sentence is composed of two independent clauses, or clauses that have a subject and a verb and can stand as complete sentences on their own. This means that to combine them into a single compound sentence, you must either use a semicolon or a comma followed by a conjunction. As written, the sentence correctly uses a semicolon to connect the two independent clauses. In addition, it correctly uses a comma after the phrase "as a result," which is functioning like an adverb.

Most of the material in these galaxies is, in fact, invisible. Since galaxies are the largest structures in the universe held together by gravity, some scientists concluded that most of the matter in the entire universe is invisible. They called this invisible material dark matter. Two scientists offer theories on whether dark matter exists.Scientist 1Recent studies by researchers at Northeastern University and the University of Victoria may suggest that dark matter—a substance previously considered viable in light of Newton’s theories of gravity—does not actually exist. Dark matter is not readily observable because it does not directly refract light or energy. Its existence could only be deduced because of the perceived gravitational effect that it has on surrounding matter.This new research is based upon Einstein’s theory of general relativity. Although Newtonian physics may provide for the cohesive nature of solar systems, when applied to galaxies the ‘numbers’ do not add up. Because there is not enough visible matter for the various gravitational equations to balance, dark matter was theorized to make up this deficit. Without a source for the rest of the missing matter, there was previously nothing in Newtonian physics to explain the movement or shape of galaxies.In terms of general relativity, a galaxy, seen collectively, has its own gravity and essentially drives its own rotation at a constant rate. Aaron Romanowsky of Harvard University and several colleagues point to the existence of several elliptical-shaped galaxies surrounded by very little dark matter as evidence that dark matter is not, in fact, the cause of the warped galaxies. The results of their studies cast doubt on some of the conventional theories of galaxy formation and manipulation.This theory does not explain everything, such as how large clusters of galaxies are able to bind to one another, but it does allow for already proven equations to explain the motion of galaxies without dark matter.Scientist 2Without dark matter, there are many cosmological phenomena that are difficult to explain. Some scientists believe that the interaction between dark matter and other smaller, nearby galaxies is causing the Milky Way galaxy to take on a warped, elliptical profile. This interaction involves two smaller galaxies (called Magellanic Clouds) near the Milky Way, moving through an enormous amount of dark matter, which in effect enhances the gravitational pull that the two Magellanic Clouds could exert on the Milky Way and other surrounding bodies. Computer models from the University of California at Berkeley seem to support this theory. Without the existence of the dark matter, the Magellanic Clouds would not have sufficient mass to have such a strong effect on the bend of the Milky Way galaxy.The strongest evidence for the validity of this hypothesis rests in Newtonian physics and the hypothesis that anything with mass will exert a gravitational pull. However, there is nothing readily observable in the vicinity of the Milky Way with sufficient mass that could cause such a high level of distortion via gravitational pull.In addition, theoretical arguments for the existence of dark matter can be made by looking at the cosmic microwave background in the universe. This “leftover” light radiation, emitted only a few hundred thousand years after the formation of the universe, provides information about conditions in the universe on a very large scale. Measurements of cosmic microwave radiation imply the existence of dark matter, although even dark matter cannot solve all of the mysteries of the universe.Q.With which of the following statements would both Scientist 1 and Scientist 2 most likely agree?

For centuries, the field has been used to aid navigation and exploration, and has been vital to many major discoveries. The magnetic field of the Earth extends several thousands of miles into space. It has the effect of shielding the Earth from solar wind, protecting the planet from dangerous high-energy particles and radiation. The exact source of the Earth’s magnetic field is not certain. The following two Scientists attempt to explain the phenomenon.Scientist 1The Earth’s magnetic field is similar to that of a bar magnet tilted 11 degrees from the spin axis of the Earth.The magnetic field of a bar magnet, or any other type of permanent magnet, is created by the coordinated motions of electrons within iron atoms. It is widely accepted that the Earth’s core consists of metals. The inner core is 70% as wide as the moon and consists of a solid iron ball, which would exhibit properties of ferromagnetism (the natural magnetic tendency of iron). The core has its own rotation and is surrounded by a “sea” of molten rock. The magnetic field grows and wanes, and the Earth’s poles drift and occasionally flip as the rotation of the core changes. The poles of the magnetic field have “flipped” many times due to the fluctuations in the rotation of the solid inner core. Other fluctuations in the magnetic field that can occur on a daily basis are largely the result of interference by solar wind.Scientist 2The Earth’s magnetic field is attributed to a dynamo effect of circulating electric current in the molten outer core. Electric currents cause magnetic fields; therefore, the circulating electric currents in the Earth’s molten metallic core are the origin of the magnetic field. When conducting fluid flows across an existing magnetic field, electric currents are induced, creating another magnetic field. When this magnetic field reinforces the original magnetic field, a dynamo is created which sustains itself.Sitting atop the hot, iron inner core, the Earth’s molten outer core churns and moves. The outer core also has cyclones or whirlpools powered by the Coriolis effects of Earth’s rotation. These complex and unpredictable motions generate the fluctuating magnetic field. The outer core is seething, swirling, and turbulent, which has been detected by the constant changes and reversals in polarity throughout the planet’s history. Further, iron has a special characteristic.When it is hotter than 1043 K, its Curie temperature, iron loses its magnetic properties. Therefore the Earth’s magnetic field is caused not by magnetised iron deposits, but mostly by electric currents in the liquid outer core.Q.Do the Scientists differ in their description of the Earth’s magnetic field?

Before modern technologies and experiments allowed scientists to understand different organisms mechanisms of reproduction, numerous theories existed about how populations came to exist. Two scientists from the 1800s describe their theories. Here are their arguments.Scientist IJust like some plants come from seeds and others are capable of vegetative (asexual) reproduction, some animal organisms come from non-sexual reproduction as well. Maggots, for example, appear on rotting carcasses. It is clearly illogical to suggest that the dead animal created or gave birth to the maggots, as it is no longer alive and is therefore incapable of sexual reproduction. The only rational conclusion for the appearance of maggots is a spontaneous generation. This is similar to how, if one were to leave a bowl of broth in the open air for a week, it would turn cloudy from bacteria appearing in the liquid.Scientist IIAnimate objects cannot arise from inanimate objects. Even when plants perform asexual reproduction, daughter plants are still coming from parent plants. There is no other example in nature of a living organism spontaneously coming into being. It is true that we observe maggots on rotting carcasses, but that does not necessarily mean that the maggots came from the rotting carcass. Similarly, bacteria growing in broth do not necessarily come directly from the broth. If a living organism appears, then it must have come from another animate object, even if we did not witness it. It is more likely that these invisible organisms have come in through the air and we simply do not see them until they have had a chance to replicate in these locations.Q. An experiment is performed in which a rotting carcass is vacuum sealed. After several weeks, no maggots are observed. The rotting carcass is removed from the vacuum seal, and several days later maggots are observed. Which theory does this best support?
