You don't need a lot of fancy equipment to get a good workout either. All you need is a well-designed pair of athletic shoes.This paragraph best supports the statement thatDeselect Answer fitness walking is a better form of exercise than weight lifting. a membership in a health club is a poor investment. walking outdoors provides a better workout than walking indoors. fitness walking is a convenient and valuable form of exercise. poorly designed athletic shoes can cause major foot injuries. Q. 2In an in Vitro study, 160 white cats were injected with Salt X. 160 other white cats were injected with placebo. In two weeks, 39% of the white cats, who were injected with Salt X showed symptoms of Kay fever. Hence it can be concluded that Kay fever is caused by some elements similar to the elements in Salt X.Which of the following statements would most seriously weaken the above discussion?Deselect Answer People suffering from Kay fever are the victims of the golden viper of Sindh. One among the 160 white cats had already showed symptoms of Kay fever prior to the experiment The natural habitats of white cats does not contain any of the elements found in Salt X. The 160 white cats used in the experiment were kept isolated from each other. The scientists administered the injections being ignorant of the contents of the salt used Q. 3Giant Motors is attempting to dominate the automobile market by promoting its products with an expensive television advertising campaign. But, the results of recent surveys reveal that, in the opinion of 85 percent of all consumers, Giant Motors already dominates the market. Since any product with more than half of all sales in any given market is already dominant, Giant Motors dominates the market now and must only preserve its market share in order to continue to dominate its market. The argument commits which one of the following errors in reasoning?Deselect Answer Failing to eliminate the possibility that what seems to be the outcome of a specific market condition might actually be the cause of the condition Confusing a condition necessary for certain outcome to obtain for a condi- tion that, alone, is sufficient to assure that result Treating the failure to establish the falsity of a specific claim as tantamount to showing that such a claim is certainly accurate Accepting evidence that a claim is believed to be true as evidence that the claim, itself, is actually true Describing the results of a survey that was done in the past as acceptably predicting future conditions Q. 4Researchers concur with one another on the issue of the harm that can result when children are exposed to microscopic asbestos fibers. The resulting disease, asbestosis, is almost always debilitating and even sometimes fatal. Many older school buildings contain asbestos insulation around hot water pipes and heating ducts because, until recently, the dangers of asbestos were unknown. Yet, these same researchers also agree that laws requiring the removal of asbestos from schools could actually lead to an increased likelihood of exposure to asbestos fibers to the students who attend those schools.Which one of the following, if true, most helps to resolve the apparent discrepancy in the researchers’ positions?Deselect Answer New insulation materials used instead of asbestos are as potentially harmful to children as asbestos is. The money that would be spent on the removal of asbestos from schools could be spent in other ways that would be more likely to increase the overall health of school children Other sources of asbestos, such as automobile and household uses, are responsible for more cases of asbestosis than school-based sources are. Removing the asbestos from older schools disperses a large quantity of asbestos fibers into the air, where they are more easily inhaled than when they are left in place around the pipes and ducts. Lead-based paint poses more of a health hazard to children than asbestos does. Q. 5Murcheson’s drawing of the Lincoln Monument contains several inaccuracies. Therefore, your attempt to reproduce the drawing of the monument will not be a very accurate reproduction of the drawing. Which one of the following is most similar in its flawed reasoning to the flawed reasoning in the argument above?Deselect Answer Katrina’s presentation was made up primarily of fabrications and distortions. So the video recording made of it cannot be of good quality. An architect who creates a model of an ugly building must necessarily create an ugly model, unless the sculpture is a distorted representation of the building. If a puppy’s coloring resembles its mother’s, then if the mother’s fur is curly, the puppy’s fur must also be curly. Kelly imitated Rory. But, Kelly is different from Rory, so Kelly could not have imitated Rory very well. Quentin’s second movie is similar to his first. Therefore, his second movie must be entertaining since his first movie won many awards.

And what accounts for this renewed interest in Shakespeare? As scholars point out, the psychological insights he portrays in both male and female characters are amazing even today.Deselect Answer Shakespeare’s characters are more interesting than fictional characters today. People today are interested in Shakespeare’s work because of the characters. Academic scholars are putting together an anthology of Shake- speare’s work. New Yorkers have a renewed interested in the work of Shake- speare. Shakespeare was a psychiatrist as well as a playwright Q. 8The Fourth Amendment to the Constitution protects citizens against unreasonable searches and seizures. No search of a person’s home or personal effects may be conducted without a written search warrant issued on probable cause. This means that a neutral judge must approve the factual basis justifying a search before it can be conducted. This paragraph best supports the statement that the police cannot search a person’s home or private papers unless they haveDeselect Answer Legal authorization. Direct evidence of a crime. Read the person his or her constitutional rights. A reasonable belief that a crime has occurred. Requested that a judge be present.

Which of the following conclusions is best supported by the data?Deselect Answer Caudal protein stimulates development of anterior structures Bicoid protein inhibits translation of caudal mRNA. Translation of bicoid mRNA produces caudal protein. Bicoid protein stabilizes caudal mRNA Caudal protein inhibits the development of bicoid Q. 20Which of the following is/are true regarding sensory receptors?They can transduce mechanical stimuli into electrical signalsThey can transduce the binding of a neurotransmitter into electrical signalsThey can transduce the binding of a chemical into electrical signalsThey can trigger an action potential in the cellDeselect Answer 1 only 2 only 1 and 2 only 1,2 and 3 only 1,3 and 4 only Q. 21The tiny blue-eyed Mary flower is often one of the first flowers seen in the spring in some regions of the United States. The flower is normally blue, but sometimes a white or pink flower variation is found. The following data were obtained after several crosses.Which of the following statements best explains the data?Deselect Answer Flower color is an inherited trait, and the F1 and F2 phenotypes of the flowers arising from the pink and white cross can best be explained by another gene product that influences the phenotypic expression. The appearance of blue in the F1 generation of the pink and white cross demonstrates that flower color is not an inherited trait but is determined by the environment. Since the F1 and F2 phenotypes of the pink and white cross do not fit the expected genotypic and phenotypic ratios, blue-eyed Mary must reproduce by vegetative propagation. Flower color depends on stages of flower development, and young flowers are white, advancing to pink and then blue. Genotype of F1 members are all homogeneous. Q. 22The endocrine system incorporates feedback mechanisms that maintain homeostasis. Which of the following demonstrates negative feedback by the endocrine system?Deselect Answer After a meal, blood glucose levels become elevated, stimulating beta cells of the pancreas to release insulin into the blood. Excess glucose is then converted to glycogen in the liver, reducing blood glucose levels. During labor, the fetus exerts pressure on the uterine wall, inducing the production of oxytocin, which stimulates uterine wall contraction. The contractions cause the fetus to further push on the wall, increasing the production of oxytocin. At high elevation, atmospheric oxygen is more scarce. In response to signals that oxygen is low, the brain decreases an individual’s rate of respiration to compensate for the difference. A transcription factor binds to the regulatory region of a gene, blocking the binding of another transcription factor required for expression. During high intensity activities heart rate increases. Q. 23Which of the following is/are true about the offspring of a Ff x Ff cross? 1/4 of the offspring will have genotype FF 1/2 of the offspring will have genotype Ff 3/4 of the offspring will have the dominant phenotype 1/3 of the offspring will have genotype ffDeselect Answer 1 and 3 only 1 and 2 only All are true 1, 2 and 3 only 2, 3 and 4 only Q. 24Different photosynthetic organisms have different types of chlorophyll molecules. The distribution of chlorophylls in several different groups of organisms is shown in the table. A plus sign (+) in the table indicates the presence of a chlorophyll, while a minus sign (-) indicates its absence.Based on the data, which of the following most likely describes the evolutionary relationship among the organisms?Deselect Answer Because green algae and flowering plants contain chloroplasts, they evolved more recently than brown algae, red algae, and cyanobacteria did. Because all of the organisms contain chlorophyll a, the organisms share a common ancestor. Because brown algae, red algae, and cyanobacteria lack chlorophyll b, they evolved before green algae and flowering plants did. Because increasingly complex forms of chlorophyll are found in red algae, brown algae, green algae, and flowering plants, respectively, this reflects the order of their appearance. Order of evolution cannot be determined with the table. Q. 25Which one of the following is NOT true of human hormones?Deselect Answer They are all chemicals Some, such as testosterone and estrogen, can be steroids They travel at the speed of blood flow A hormone may affect one or more structures in the body They are all released from glands and flow down ducts into the bloodstream Q. 26The chemical reaction for photosynthesis is6 CO₂ + 12 H₂O + light energy C₆H₁₂O₆ + 6 O₂ + 6 H₂OIf the input water is labeled with a radioactive isotope of oxygen, 18O, then the oxygen gas released as the reaction proceeds is also labeled with 18O.
