MCAT Example Questions

Hello sir, can any one here provide me some question on MCAT exam. Now in those days I’m preparing for MCAT exam. For this exam preparation I want some MCAT example questions please provide me?

The Medical College Admission Exam (MCAT) is widely considered to be one of the most difficult academic tests in existence.

It is the official test a person must pass in order to be admitted to a school of medicine in the United States. MCAT sample questions to test your MCAT biology, physics and organic chemistry skills

Here I’m giving you some MCAT example questions:

Biology Sample Question
Passage (Questions 1–2)
In an attempt to develop a vaccine for pneumonia, Fred Griffith performed a series of experiments in 1928 using mice and two strains of the pneumococcus bacteria: a virulent encapsulated strain and a nonvirulent unencapsulated strain. The encapsulated strain was called the "smooth strain" because the colonies looked smooth on a culture plate due to their polysaccharide capsules, whereas the unencapsulated strain was denoted as the "rough strain" due to the irregularity of its surface.

Four different groups of mice were injected with different combinations of the bacterial strains. The experimental results are shown in Table 1.

Table 1: Results of Griffith's experiment

Mice Injected Bacteria Result
1 Live smooth Died
2 Live rough Survived
3 Heat-killed smooth Survived
4 Heat-killed smooth + live rough Died
Autopsies performed on Group 4 mice revealed blood samples filled with live smooth-strain bacteria. Some component had been transferred from the heat-killed smooth-strain bacteria to the live rough-strain bacteria, transforming them into the virulent smooth-strain bacteria. This process later became known as transformation. Griffith believed the protein from the dead smooth-strain bacteria was the active transforming agent.

2.A colony of smooth strain bacteria is grown on a culture containing an experimental drug that cleaves nucleic acid base sequences wherever adenine is paired with uracil. Which of the following processes will be directly affected?
Transcription
Translation
Transformation

I only
I and II only
I and III only
I, II and III


3.If Griffith had injected a fifth group of mice with a combination of heat-killed rough strain and heat-killed smooth strain, would the mice have died?
No, because the heat-killed rough strain cannot infect mice.
No, because the heat-killed smooth strain cannot transform mice cells.
Yes, because the heat-killed rough strain is transformed into the smooth strain.
Yes, because the mice do not have acquired immunity to pneumococcus bacteria.



Physics Sample Question
4. In which of the following cases will the normal force on a box be the greatest?
When the box is placed in a stationary elevator
When the box is placed in an elevator moving upwards at constant velocity
When the box is placed in an elevator accelerating downward
When the box is placed in an elevator accelerating upward


Organic Chemistry Sample Question
5. Which of the following addition reactions occurs the fastest?

I, because a primary cation is formed in the rate-determining step
II, because the cation formed in the rate-determining step is stabilized through an inductive effect
III, because a secondary cation which is resonance-stabilized is formed in the rate-determining step
II, because a secondary cation which is resonance-stabilized is formed in the rate-determining step

Physical Science

6. A hockey puck of mass 0.16 kg is slapped so that its velocity is 50 m/sec. It slides 40 meters across the ice before coming to rest. How much work is done by friction on the puck?

(A) +4 J
(B) –60 J
(C) –200 J
(D) –340 J

Biological Science

A variety of staining techniques are routinely used in the microbiology laboratory to identify bacteria. Some stains are simple stains while others are differential. Many of the basic dyes used bind to the bacterial cell due to its negatively charged surface. Other dyes may be repelled by the cell, and can be used to produce a negative stain. The choice of technique depends on the type of information needed. The information is routinely used to help identify microorganisms, and it also helps determine appropriate therapeutic treatment.

7. The most widely-used differential stain for bacteria is:

(A) the capsule stain.
(B) the Gram stain.
(C) the endospore stain.
(D) the flagella stain.

8. All of the following are true statements about the brain EXCEPT:

(A) The pons functions to link the cerebellum with the higher conscious centers.
(B) The limbic system alerts the cortex of incoming stimuli.
(C) The limbic system is associated with emotional responses.
(D) The nuclei of cranial nerves 5, 6, 7, and 8 are located in the pons.

Writing Sample (sample only)

A popular fear of Americans is that our nation will be "one large, paved parking lot with border-to-border interstate highways connecting it."

Write an essay in which you perform the following tasks: explain what you think the statement means; describe specific situations in which there is evidence of a growing change in the countryside of this nation; discuss ways that the statement may not be necessarily true; provide evidence of what this means to today's society; conclude with a justification of the positive or negative implications.
