42.

Which punctuation mark best completes the sentence?

I wanted to scream out his name__ but I couldn’t find my voice.

  • ,

  • ;

  • .

  • :

Correct answer: ,

A comma (,) is the punctuation mark that best completes the sentence. I wanted to scream out his name, but I couldn’t find my voice. A comma is used between two independent clauses joined by a coordinating conjunction (i.e., but).

A period (.) would cause the sentence to become two separate sentences, which would not signify that the second clause clarifies the first clause. A semicolon (;) would be used to join the two independent clauses when a transitional phrase or a conjunctive adverb is used, not when a coordinating conjunction is used. A colon (:) is not used to join two independent clauses together.

43.

A 1.5-kg block on a rafter is given a push so that it slides along the rafter. If the block is accelerated at 5 m/s2, what is the force applied to the block?

  • 7.5 N

  • 6.5 N

  • 3.3 N

  • 0.3 N

Correct answer: 7.5 N

To determine the force applied to the block, use Newton’s second law: F = ma. Where m = the mass of the block and a = the block’s acceleration.

F = ma

F = 1.5 kg x 5 m/s2

F = 7.5 N

44.

The cost of advertising an item for one minute on the radio is $242. If this includes 7.5% sales tax, what is the cost of advertising before tax?

  • $225

  • $425

  • $260

  • $240

Correct answer: $225

The cost of the advertising before tax is 100% of the advertising price, and tax is 7.5%.

Therefore, the total price of the advertising plus tax is 100% + 7.5% = 107.5%.

We can set up a ratio to determine the price without tax:

 100   =  x 
107.5   242

Cross-multiply to solve: (100 × 242) = (107.5)(x)

(100 × 242) = 24,200

24,200 = 107.5x

x = (24,200/107.5)

x = ~$225

45.

How is an ion created?

  • By the addition or subtraction of electrons

  • By the addition or subtraction of protons

  • By the equalization of electrons and protons

  • By the equalization of electrons, protons, and neutrons

Correct answer: By the addition or subtraction of electrons

An ion is created by the addition or subtraction of electrons. If an ion has fewer electrons providing a positive charge, it is called a cation. If an ion has extra electrons providing a negative charge, it is called an anion.

By the addition or subtraction of protons is incorrect because the number of protons in an atom remains constant. The equalization of electrons and protons is incorrect because this factor would cause an atom to be neutrally charged. The equalization of electrons, protons, and neutrons is incorrect because this action would not create an ion.

46.

Dividing a number by 10 is the same as multiplying that number by what?

  • 1/10

  • 1/5

  • 5

  • 10

Correct answer: 1/10 

Is x represents a number, then that number divided by 10 is x/10. Multiply x by each answer to find one that equals x/10.

x × 1/5 = x/5, so 1/5 is not the correct answer.

x × 5 = 5x, so 5 is not the correct answer.

x × 10 = 10x, so 10 is not the correct answer.

x × 1/10 = x/10, so 1/10 is the correct answer.

47.

Which of the following are large biological molecules consisting of one or more chains of amino acids?

  • Proteins

  • Chromosomes

  • Genes

  • Protons

Correct answer: Proteins

Proteins are large biological molecules consisting of one or more chains of amino acids.

Chromosomes are organized structures of DNA and protein found in cells. Genes are molecular units of heredity of a living organism. Protons are stable subatomic particles that have a positive charge.

48.

Which of the following words is spelled correctly?

  • Lighted

  • Lightted

  • Lighttid

  • None of these

Correct answer: Lighted

When adding a suffix (-ed) to a root word that ends in a single consonant, double the consonant if a single vowel directly precedes the consonant and the consonant ends with an accented syllable or one-syllable word. In this case, light ends with a single consonant (t) and a single vowel does not directly precede this consonant; instead, a consonant (h) precedes it. Therefore, you would not double the final consonant (t) and the proper spelling would be lighted.

To summarize, this rule is applied when four things are true:

  1. Does the word end in a single consonant?
  2. Does the word have only one directly preceding vowel?
  3. Does the suffix you are going to add begin with a vowel?
  4. Is the last syllable accented?

In some cases, there isn't a definitive spelling for a word when it comes to this double the consonant rule. Examples include traveling/travelling, canceled/cancelled, profitable, worshiped.

49.

Which bone in a human body is the longest and the strongest?

  • Femur

  • Patella

  • Tibia

  • Fibula

Correct answer: Femur

The femur is the longest and the strongest bone in a human body. The femur bone has a hemispherical head that articulates with the acetabulum of the pelvis, forming a ball-and-socket joint.

The patella is the kneecap. The tibia is a leg bone that is the only weight-bearing bone in the crural region. The fibula is a bone that helps to stabilize the ankle.

50.

Which of the following endocrine system glands is primarily responsible for regulating an individual's metabolism and energy?

  • Thyroid gland

  • Adrenal glands

  • Parathyroid gland

  • Pineal gland

Correct answer: Thyroid gland

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 thyroid is responsible for regulating an individual's metabolism and energy. The thyroid is found in the front of an individual's neck.

The parathyroid gland helps control an individual's calcium and phosphorous levels. The pineal gland informs the body when it is time to sleep. The adrenal glands produce a variety of hormones which regulate blood sugar, help the body utilize carbohydrates and fats, distribute stored fat, and promote cardiovascular and gastrointestinal functions. While the adrenal glands help regulate metabolism, it is not their primary function.

51.

In regard to an atom’s structure, which of the following statements is true?

The noun written in the correct plural form is jalopies. When a noun ends in “y” and is preceded by a consonant, the “y” is changed to an “i” and “es” is added to form a plural.

The plural form of fly is flies. The plural form of lunch is lunches. The plural form of wife is wives.

57.

How would 1.05 be displayed as a fraction?

  • 21/20

  • 105/10

  • 20/21

  • 15/100

Correct answer: 21/20

To convert 1.05 into a fraction, first change it into an improper fraction.

1 5/100 = (100 × 1 + 5)/100 = 105/100

Reduce the fraction by dividing both numerator and denominator by 5.

105/100 ÷ 5/5 = 21/20
