Nobody knows how, where or when life originated. About all that is known for certain is that microbial life had established itself on Earth by about three and a half billion years ago. In the absence of hard evidence of what came before, there is plenty of scope for disagreement. Thirty years ago the prevailing view among biologists was that life resulted from a chemical fluke so improbable it would be unlikely to have happened twice in the observable universe. That conservative position wasexemplified by Nobel Prize–winning French biologist Jacques Monod, who wrote in 1970: “Man at last knows that he is alone in the unfeeling immensity of the universe, out of which he emerged only by chance.” In recent years, however, the mood has shifted dramatically. In 1995renowned Belgian biochemist Christian de Duve called life “a cosmic imperative” and declared “it is almost bound to arise” on any Earth-like planet. De Duve’s statement reinforced the belief among astrobiologists that the universe is teeming with life. Dubbed biological determinism byRobert Shapiro of New York University, this theory is sometimes expressed by saying that “life is written into the laws of nature.” How can scientists determine which view is correct? The most direct way is to seek evidence for life on another planet, such as Mars. If life originatedfrom scratch on two planets in a single solar system, it would decisively confirm the hypothesis of biological determinism. Unfortunately, it may be a long time before missions to the Red Planet are sophisticated enough to hunt for Martian life-forms and, if they indeed exist, to study such extraterrestrial biota in detail. An easier test of biological determinism may be possible, however. No planet is more Earthlike than Earth itself, so if life does emerge readilyunder terrestrial conditions, then perhaps it formed many times on our home planet. To pur sue this tantalizing possibility, scientists have begun searching deserts, lakes and caverns for evidence of “alien” life-forms—organisms that would differ fundamentally from all known livingcreatures because they arose independently. Scientists have yet to reach a consensus on a strict definition of life, but most would agree that two of its hallmarks are an ability to metabolize (to draw nutrients from the environment, convert those nutrients into energy and excrete waste products) and an ability to reproduce. The orthodox view of biogenesis holds that if life on Earth originated more than once, one form would have swiftly predominated and eliminated all the others. This extermination might have happened, for example, if one form quickly appropriated all the available resources or “ganged up” on a weaker form of life by swapping successful genes exclusively with its own kind. But this argument is weak. Bacteria and archaea, two very different types of microorganisms that descended from a common ancestor more than three billion years ago, have peacefully coexisted ever since, without one eliminating the other. Moreover, alternative forms of life might not have directly competed with known organisms, either because the aliens occupied extreme environments where familiar microbes could not survive or because the two forms of life required different resources. Even if alternative life does not exist now, it might have flourished in the distant past before dying out for some reason. In that case, scientists might still be able to find markers of their extinct biology in the geologic record. If alternative life had a distinctively different metabolism, say, it might have altered rocks or created mineral deposits in a way that cannot be explained by the activities of known organisms. Biomarkers in the form of distinctive organic molecules that could not have been created by familiar life might even be hiding in ancient microfossils, such as those found in rocks dating from the Archean era (more than 2.5 billion years ago). A more exciting but also more speculative possibility is that alternative life-forms have survived and are still present in the environment, constituting a kind of shadow biosphere. At first this idea might seem preposterous; if alien organisms thrived right under our noses (or even in our noses), would not scientists have discovered them already? It turns out that the answer is no. The vast majority of organisms are microbes, and it is almost impossible to tell what they are simply by looking at them through a microscope. Microbiologists must analyze the genetic sequences of an organism to determine its location on the tree of life—the phylogenetic grouping of all known creatures—and researchers have classified only a tiny fraction of all observed microbes.We speak of life: (see text )Deselect Answer when water is used when there is a minimum sensibility if the brain is sufficiently developed in presence of a growth process in presence of metabolism and reproduction Q. 2An alien life-form is: (see text )Deselect Answer any unknown microorganism an organism coming from other planets a life-form originating by a different evolution an organism that lives in an atmosphere with no oxygen an anaerobic form of life Q. 3The studies on the most ancient geological strata: (see text)Deselect Answer do not distinguish alternative forms of life have already provided secure evidence can never be considered decisive might contain different metabolic traces highlight only known bio-markers Q. 4According to biological determinism, life: (see text )Deselect Answer follows from exceptional circumstances arises by a natural evolution requires an Earth-like environment is only present in the solar system has extra-galactic origins Q. 5Arnold Schwarzenegger was the governor of which American state?Deselect Answer Florida Texas Montana California New Mexico Q. 6Which actor played Rocky?Deselect Answer Tony Burton Sylvester Stallone Harrison Ford Jason Statham Robert De Niro Q. 7Which building was not attacked on 9/11?Deselect Answer World Trade Center South Tower World Trade Center North Tower The Pentagon The Marriott Hotel Statue of Liberty Q. 8What is the capital city of Australia?Deselect Answer Sydney Melbourne Canberra Brisbane Adelaide Q. 9A robot is programmed to apply the following instructions in order to move through a maze:If it is possible to move forwards, then move one space forwardsIf it is not possible to move forwards, then keep turning right until it is possible to move forwards again.The robot is placed in the square at the bottom left of the maze (marked R on the diagram).How many of the squares will the robot move through before leaving the maze?Deselect Answer 6 8 9 10 11 Q. 10The table below shows the prices that a supplier charges for exercise books.
