Which option appropriately follows the rules of capitalization?

  • Alexander the Great

  • the Rocky mountains

  • Sequoia national park

  • North to Alaska

Correct answer: Alexander the Great

The only option that appropriately follows the rules of capitalization is “Alexander the Great.” Formal epithets (term used to characterize a person) are capitalized.

The proper capitalization for the other options are: the Rocky Mountains (the full name of landforms are capitalized), Sequoia National Park (the names of public areas are capitalized), and north to Alaska (since north is providing direction, it is not capitalized).

104.

Which type of solution combines readily separate matter?

  • Emulsions

  • Compounds

  • Alloys

  • Amalgams

Correct answer: Emulsions

Emulsions are solutions that combine readily separate matter. An example of an emulsion is water and oil, as these two types of matter readily separate.

Compounds are solutions that create a single matter by mixing different elements. Alloys are solutions that make a new type of metal by combining solid solutions of other metals. Amalgams are solutions that use mercury to dissolve another metal type.

The rate of gravity (g) on Earth has a value of ______.

  • 9.81 m/s²

  • 9.87 m/s

  • 90.8 m/s²

  • 3.14 m/s

Correct answer: 9.81 m/s²

The rate of gravity (g) on Earth has a value of 9.81 m/s². Because it is a measurement of acceleration, its unit of measure is meters per second squared, or "meters per second per second."

106.

The luteinizing hormone (LH, also known as lutropin and sometimes lutrophin) is produced by the pituitary gland. What does the luteinizing hormone help the body do?

  • Regulate estrogen and testosterone

  • Cause birthing contractions to start at the appropriate time

  • Regulate the body's water balance

  • Develop a healthy immune system

Correct answer: Regulate estrogen and testosterone

The endocrine system is a set of organs that secrete hormones directly into the circulatory system. Its principal functions are hormone production and internal communication and coordination. The major glands in the endocrine system are the pineal, hypothalamus, pituitary, thyroid and parathyroid, thymus, adrenal, pancreas, and ovaries or testes. These glands send hormones through the blood to other organs and tissues in the body to control the function of that organ.

The luteinizing hormone (LH, also known as lutropin and sometimes lutrophin) helps the body regulate estrogen and testosterone.

The oxytocin hormone causes birthing contractions to start at the appropriate time. The antidiuretic hormone regulates the body's water balance. The thymus helps the body develop a healthy immune system.

107.

A wave moves through its medium at 40 m/s with a wavelength of 5 m. What is the frequency of the wave?

  • 8 s-1

  • 0.13 s-1

  • 15 s-1

  • 0.76 s-1

Correct answer: 8 s-1

To find the frequency of the wave, convert the equation v = fl to solve for frequency: f = v/l. Where v = velocity and l = wavelength.

f = v/l

f = 40 m/s / 5 m

f = 8 s-1

John adopted his dog exactly 5 years and 12 days ago. At this instant, how many minutes has John had his dog? (Ignore leap years.)

  • 2,645,280 minutes

  • 2,217,116 minutes

  • 3,098,732 minutes

  • 1,872,234 minutes

Correct answer: 2,645,280 minutes

Start by finding the number of days in 5 years.

1 year = 365 days

1 year x 5 = 365 days x 5 = 1,825 days

Add the 12 days.

1,825 days + 12 days = 1,837 days

Convert the number of days to hours.

1 day = 24 hours

1 day x 1,837 = 24 hours x 1,837 = 44,088 hours

Convert the number of hours to minutes.

1 hour = 60 minutes

1 hour x 44,088 = 60 minutes x 44,088 = 2,645,280 minutes

How many bones make up the adult skeletal system?

  • 206

  • 120

  • 314

  • 194

Correct answer: 206

The skeletal system has three main functions: movement, protection, and metabolism. The skeletal system is composed of bone, which is an organ that is constantly being reorganized. Bones synthesize blood and immune cells, as well as store calcium, phosphate, and lipids. Bone is a dynamic tissue that is made and broken down according to need. It also functions to provide structural, protective, and metabolic needs.

The skeletal system in an adult body is made up of 206 individual bones. These bones are arranged into two major divisions: the axial skeleton and the appendicular skeleton.

  • The axial skeleton runs along the body’s midline axis and is made up of 80 bones in the following regions: Skull, hyoid, auditory ossicles, ribs, sternum, vertebral column
  • The appendicular skeleton is made up of 126 bones in the following regions: Upper limbs, lower limbs, pelvic girdle, pectoral (shoulder) girdle

112.

Which of the following punctuation marks is used for words and figures in order to clarify something?

  • Parentheses

  • Periods

  • Commas

  • Quotation marks

Correct answer: Parentheses

Parentheses are used for words and figures to clarify something.

For example: "For the last five years (some say longer), the house on the hill has been haunted."

113.

Which of the following is used to predict the possible genotype and phenotype of offspring in sexual reproduction?

  • Punnett square

  • Mendel triangle

  • Calvin cycle

  • Darwin circle

Correct answer: Punnett square

A Punnett square is comprised of two columns and two rows. The two parent genotypes are placed on the rows and columns, and the potential phenotypes are in the boxes of the squares.

5/9 + 2/7 =

  • 53/63

  • 7/9

  • 7/16

  • 1/3

Correct answer: 53/63

1. Find the Least Common Denominator (LCD) of 5/9,2/7

Method 1: By Listing Multiples List out all multiples of each denominator, and find the first common one.

9 : 9,18,27,36,45,54,63

7 : 7,14,21,28,35,42,49,56,63

Therefore, the LCD is 63.

Method 2: By Prime Factors List all prime factors of each denominator, and find the union of these primes.

9 : 3,3

7 : 7

Therefore, the LCD is 3×3×7=63

2. Make the denominators the same as the LCD

(5×7)/(9×7) + (2×9)/(7×9)

3. Simplify - Denominators are now the same

35/63 + 18/63

4. Join the denominators

(35+18)/63

What is the meaning of the word “glimmer” as it is used in the passage?

  • A small amount

  • A dim glow

  • A faint flashing light

  • A sparkle

Correct answer: A small amount of something

The word “glimmer” is used in the passage to mean a small amount of hope. The word “glimmer” is located in the passage’s second paragraph: “A recent study in mice has given a glimmer of hope for people who have lost their hair…” Using the context, the reader can determine that people, who have lost their hair, have a small amount of hope in using stem cells to restore their hair.

The other options are incorrect because they would not correctly fit into the context of the passage, as people would not have a dim glow of hope, a faint flashing light of hope, or a sparkle of hope.

116.

Which of the following bones is an example of a long bone?

  • Ulna

  • Patella

  • Sternum

  • Ribs

Correct answer: Ulna

There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.

  • Flat: Flat bones primarily protect internal organs. Examples are the scapula, ribs, and sternum. There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and pubis). Their function is to protect internal organs such as the brain, heart, and pelvic organs.
  • Long: Long bones support weight and facilitate movement. They are longer than they are wide. Long bones include the femur (the longest bone in the body) as well as relatively small bones in the fingers. They function to support the body's weight and facilitate movement. Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).
  • Short: Located in the wrist and ankle joints, short bones provide stability and some movement and are about as long as they are wide. The carpals in the wrist (scaphoid, lunate, triquetral, hamate, pisiform, capitate, trapezoid, and trapezium) and the tarsals in the ankles (calcaneus, talus, navicular, cuboid, lateral cuneiform, intermediate cuneiform, and medial cuneiform) are examples of short bones.
  • Irregular: Irregular bones vary in shape and structure and therefore do not fit into any other category (flat, short, long, or sesamoid). They often have a fairly complex shape, which helps protect internal organs. For example, the vertebrae, irregular bones of the vertebral column, protect the spinal cord. The irregular bones of the pelvis (pubis, ilium, and ischium) protect organs in the pelvic cavity.
  • Sesamoid: Sesamoid bones are embedded in tendons. These small, round bones are commonly found in the tendons of the hands, knees, and feet. Sesamoid bones function to protect tendons from stress and wear. The patella (kneecap) is an example of a sesamoid bone.

If during the revision stage of writing you find that you did not maintain the proper voice throughout the writing process, what should you do?

  • Rework the material

  • Delete information

  • Move material

  • Add information

Correct answer: Rework the material

If during the revision stage of writing you find that you did not maintain the proper voice throughout the writing process, you should rework the material. You should also rework the material if it is confusing or unclear and if it needs to be simplified.

Information should be deleted if it doesn’t support the writing or if it is redundant. Material should be moved around to create a clear flow, to present points in order, or to make a dramatic impact. Information should be added in order to share more details, to clarify an idea, or to link sentences or paragraphs to improve flow.

Determine the momentum of a 75-kg football player who is running southward at 2 m/s.

  • 150 kg × m/s south

  • 37.5 kg × m/s south

  • 300 kg × m/s south

  • 18.75 kg × m/s south

Correct answer: 150 kg × m/s south

The football player’s momentum is 150 kg × m/s south. The formula for momentum is:

Mass × Velocity

Thus, 75 kg × 2 m/s = 150 kg × m/s south.

119.

If a box with a mass of 1.2 kg is held 2.4 m above the ground, what would the box’s gravitational potential energy be?

  • 28.22 J

  • 2.88 J

  • 6.91 J

  • 32.18 J

Correct answer: 28.22 J

To determine the box’s gravitational potential energy, use the following equation: PE = mgh where m equals mass, g equals gravitational constant (9.8 m/sec2), and h equals height.

PE = mgh

PE = (1.2 kg)(9.8 m/sec2)(2.4 m)

PE = 28.22 J
