Sample Practice Test Questions
What part of the brain is responsible for the major senses (thinking, hearing, seeing)?
cerebrum
The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).
Which of these is not a component of blood?
marrow
Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.
The mechanical advantage of a gear train is its gear ratio. The gear ratio (Vr) is the product of the gear ratios between the pairs of meshed gears. Let N represent the number of teeth for each gear:
Vr = \( \frac{N_1}{N_2} \) \( \frac{N_2}{N_3} \) \( \frac{N_3}{N_4} \) ... \( \frac{N_n}{N_{n+1}} \)
In this problem, we have three gears so the equation becomes:
Vr = \( \frac{N_1}{N_2} \) \( \frac{N_2}{N_3} \) = \( \frac{24}{16} \) \( \frac{16}{4} \) = \( \frac{24}{4} \) = 6
Which of the following describes how a person's genes express themselves in physical characteristics?
phenotype
A person's genotype is their genetic makeup and includes both dominant and recessive alleles. Phenotype is how the genes express themselves in physical characteristics.
Connecting the 8 batteries in series multiplies their voltage while keeping their current the same yielding a 72V 15A configuration. Connecting the 8 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 9V 120A configuration. Using a series-parallel connection, 4 batteries can be connected in series and 4 can be connected in parallel resulting in a 36V 60A configuration.
The Earth's rocks fall into three categories based on how they're formed. Which of the following is formed when existing rock is altered through pressure, temperature, or chemical processes?
metamorphic
The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.
If AD = 29 and BD = 22, AB = ?
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDAB = 29 - 22
AB = 7
This diagram represents two parallel lines with a transversal. If b° = 140, what is the value of x°?
For parallel lines with a transversal, the following relationships apply:
- angles in the same position on different parallel lines equal each other (a° = w°, b° = x°, c° = z°, d° = y°)
- alternate interior angles are equal (a° = z°, b° = y°, c° = w°, d° = x°)
- all acute angles (a° = c° = w° = z°) and all obtuse angles (b° = d° = x° = y°) equal each other
- same-side interior angles are supplementary and add up to 180° (e.g. a° + d° = 180°, d° + c° = 180°)
Applying these relationships starting with b° = 140, the value of x° is 140.
