While the primary test day always takes place during the school week, there is also an opportunity to take the test on the following Saturday. If you are unable to take the test on either of these days, there is also one alternative test date that is predetermined by the test administrators. You can find the exact dates for the next testing period right here. At many high schools, PSAT registration is mandatory for every student, and the registration fees are covered by the school. However, this is not always the case. If your school does not offer registration for the PSAT, you may need to register and pay for the test through a nearby school. You can register online at this link. The deadline for test registration is usually about one month prior to the test dates, though the exact deadline varies each year. When you arrive on the test day, you will need to make sure you have everything you need. Since you will be seated for an extended period of time, you should remember to wear comfortable clothing.

View Correct Answer Answer: C According to Figure 3, almost all of the irradiance is delivered in the visible light, infrared, and ultraviolet spectra. The magnitude of irradiance delivered by the other types does not even appear clearly on the graph. The ultraviolet irradiance is defined by the small sliver of area under the curve between 0 and nm. The infrared area from to 2, nm is significantly larger. ACT Science Passage V—Research Summary Microbe populations, including those of disease-producing bacteria, can change their characteristics over relatively short periods of time. A series of experiments involving pneumococci were conducted to determine whether and how these changes take place. In all three of the experiments described here, measures were taken to protect against contamination from other bacteria throughout the course of the experiments. Experiment 1 A five-year study was conducted of the prevalence of each type of pneumococcus found in pneumonia victims.
PSAT/NMSQT Practice Test #1 - The College Board
Table 1 shows the results. For the purpose of simplification, the pneumococcal types I through VI referred to here do not necessarily correspond either to those used in the original study or to those in current usage. Experiment 2 A subsequent study was conducted to determine what happens to strains of pneumococci in a disease victim. It examined changes both to the pneumococci infecting the victim and to those extracted from the victim. First, samples were taken from a patient who was initially analyzed to be infected only with type I pneumococci.

Cultures were grown from these samples in three ways and analyzed. The first was simply to grow bacterial colonies from the sample in petri dishes. The second was to examine what happened when the same bacteria infected others. Mouse A was inoculated with untreated infected material. Then mouse B was inoculated with type I serum, which kills type I bacteria, and with the infected material from the patient. Table 2 reports those results. Note: each day a different mouse B and mouse A were used. Experiment 3 The next experiment examined the changes that occurred when bacteria from six different pneumococcal colonies were used to inoculate mice.

These colonies were cultured in laboratory conditions to eliminate uncertainties of the previous experiments. All of these colonies were of rough R bacteria. Bacteria can be divided into smooth or encapsulated S and rough or unencapsulated R. The smooth, encapsulated bacteria are the most dangerous because they are coated with material that protects them from antigens.
CogAT Practice Test and Online Worksheets
The rough, unencapsulated bacteria are usually harmless. In each case, a mouse was inoculated with R bacteria from the colony. The mice either died after between 2 and 12 days or survived indefinitely. The blood of each deceased mouse was then cultured and tested for pneumococci that were examined to determine whether they were R or S bacteria. Table 3 reports the results.
Practice Tests
Based on the overall findings reported by Table 2, which of the following answers is most correct? The mice became infected with whatever bacteria the patient was infected with when the sample was taken. The appearance of type VI bacteria indicates that the disease has run its course. Bacteria change by escalating from lower types to higher types. Type I dominated the results of the inoculated mouse A, but it did not appear in the day 15 or 17 samples. It then reappeared on day 19, along with type VI, but reappeared alone on day 21 even though the culture from the patient grew no colonies.

Answer choice A is not correct. On days 4 and 6, mouse B was infected with types V and VI pneumococci, without any evidence that these were in the sample from the patient. On day 8 mouse A was infected with type VI, which did not appear in the patient until day Answer choice C draws a conclusion based on how the bacterial types were numbered, rather than on the observed operation of the bacteria. From the standpoint of understanding how bacterial strains change over time, what is the most interesting thing about the results reported in Table 3?
GRE Math Practice: Questions & Explanations
Any of the mice survived. All of the bacterial strains, without exception, changed from R to S. There was only one fatality in the mice inoculated with strains 4 and 6, and that took much longer than the deaths caused by the other strains. All of the bacterial strains extracted and tested exhibited a change from R to S. View Correct Answer Answer: D The consistency of this result is a strong indicator that the colonies do change their characteristics in a systematic way. Answer choices A and C indicate only that some strains are more virulent than others, but that is to be expected. Answer choice B incorrectly claims that all of the samples changed, but the surviving mice were not tested.
PSAT 8/9 Practice Test #1
Which answer is the most important statement supported by the data reported from the three experiments? All bacteria are potential killers. Pneumococcus strains do apparently shift their characteristics significantly over time, and it is possible to learn about the conditions under which this happens. Mice are more susceptible to disease than humans.

Bacteria undergo random mutations that we cannot predict. View Correct Answer Answer: B The consistency of this result is a strong indicator that the colonies do change their characteristics in a systematic way. Which statement is best supported by the data in Table 2, viewed in conjunction with the other data?

A single type of bacterium infects the victim and then reproduces until it kills the patient or the patient kills it. The progress of the disease involves changes not only in the intensity but also in the nature of the infection. The bacterial strain causing the infection will tend to destroy itself. The bacteria can never be completely eliminated. View Correct Answer Answer: B It is important to be able to look at the data presented and draw conclusions from what seems to make sense based on other inputs. The idea that one stable form of bacteria is at work from the beginning to the end of this course of illness is refuted. Answer choice B is refuted by the data.
Algebra 1 Worksheets
Answer choice C is not supported. The original type I strain seems to have been weakened or transformed to others, but there is no evidence that it destroyed itself. There is also nothing to support answer choice D. ACT Science Passage VI—Data Representation Variations in the proportion of the two major isotopes of oxygen, 18O and 16O, in seawater or landbased water, including glacial ice, are believed to be a proxy for changes in temperature. This leaves a higher concentration of 18O in seawater and a lower concentration in the evaporated water, which then falls to Earth as precipitation.
MCAT Practice Tests
If the falling water freezes, glaciers are formed, which trap the low 18O precipitated water. In glacial periods, oceans are richer in 18O, but in interglacial periods the glaciers melt and 16O-rich water flows back into the oceans. For this reason high 18O concentrations in seawater are believed to be an indication of cold climate periods in which glaciers are built up.
