Identify the part of speech of themselves in the following sentence.

The children were happy with themselves for successfully building a sandcastle.

  • Pronoun

  • Noun

  • Adverb

  • Adjective

Correct answer: Pronoun

Themselves is a pronoun, as it is being used in the place of “children.” A pronoun is a word used in place of a noun.

An adjective modifies a noun. An adverb modifies a verb, an adjective, or another adverb. A noun names a person, place, thing, or idea.

43.

Which of the following is an example of an ionic bond?

  • NaCl

  • OH-

  • H3O+

  • COO-

Correct answer: NaCl

Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions. These ions represent atoms that have lost one or more electrons (known as cations) and atoms that have gained one or more electrons (known as an anion). NaCl is an example of an ionic bond because it does not have a charge.

  • -fy

  • -cal

  • -cally

  • -fication

Correct answer: -fy

Mystify is the verb form of mystics.

Mystical is the adjective form. Mystically is the adverb form. Mystification is another noun form.

48.

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.

49.

Which type of muscle tissue can be controlled consciously?

  • Skeletal

  • Nervous

  • Cardiac

  • Smooth

Correct answer: Skeletal

The purpose of muscle tissue is to produce movement. This group includes skeletal muscle, cardiac muscle, and smooth muscle.

  • Skeletal muscle is connected to bones and is used for voluntary movement; movements that are consciously controlled.
  • The only cardiac muscle in the body is the heart, and its movement is involuntary, which means it cannot be controlled consciously.
  • Smooth muscle is also controlled involuntarily. This group of muscles are located in the walls of the hollow organs. Some examples of where smooth muscle tissue is found include the bladder, the uterus, blood vessels, and intestines.

50.

If Don weighs 250 pounds, what is his approximate weight in kilograms?

  • 113 kg

  • 250 kg

  • 300 kg

  • 125 kg

Correct answer: 113 kg

Use a unit conversion fraction using the fact that 1 kilogram (kg) is approximately 2.2 pounds (lb):

250 lb × 1 kg / 2.2 lbs = 113 kg

51.

The organelle that transports material from the endoplasmic reticulum (ER) to other parts of the cell is known as which of the following?

  • Golgi apparatus

  • Nucleus

  • Chloroplasts

  • Cellular membrane

Correct answer: Golgi apparatus

The organelle that transports material from the ER to other parts of the cell is known as the Golgi apparatus. The Golgi apparatus is the cell's packaging, processing, and shipping organelle.

The nucleus is the organelle that contains the cell's DNA. Chloroplasts are the organelles that produce a plant cell's energy. Cellular membrane is the organelle that provides the cell with protection, a means of communication, and the passage of substances.

52.

Convert 19/10 to a decimal.

  • 1.9

  • 19.0

  • 190.0

  • 0.19

Correct answer: 1.9

To convert a number divided by 10 to a decimal, move the decimal point of the numerator one place to the left. Thus 19/10 becomes 1.9.

53.

Which of the following is a lipid that is a membrane component and a precursor to significant hormones?

  • Steroids

  • Proteins

  • Carbohydrates

  • Nucleic acids

Correct answer: Steroids

Steroids are lipids that are membrane components and precursors to significant hormones. Lipids are known as fats, and they include steroids, fatty acids, and phospholipids.

Proteins, carbohydrates, and nucleic acids are not classified as lipids, but they are all biologic molecules.

54.

What is the primary function of amino acids?

  • To form proteins

  • To provide energy for the body

  • To regulate metabolism

  • To transport oxygen

Correct answer: To form proteins

55.

If a box has a length of 3 units, a width of 4 units, and a height of 5 units, what is the surface area of the box?

  • 94 square units

  • 60 square units

  • 47 square units

  • 120 square units

Correct answer: 94 square units

The surface area of a box is found by 2(L⋅W + L⋅H + W⋅H) where L = length, W = width, and H = height.  

Substitute the known values.
L = 3 units, W = 4 units, and H = 5 units
2⋅(3⋅4+3⋅5+4⋅5) 
2⋅(12+15+20) 
2⋅47 = 94 square units

56.

Two men joined the military. The first man's height was 72 1/2 inches, and the second man's height was 68 1/6 inches. What was the total height of the two men?

  • 140 2/3 inches

  • 140 1/3 inches

  • 72 2/3 inches

  • 68 1/2 inches

Correct answer: 140 2/3 inches

Add the whole parts of the numbers.
72 + 68 = 140 inches.

Add the fractional parts of the numbers.
1/2 + 1/6
Since 6 is a multiply of 2 and 6, write both fractions with 6 as the denominator, giving
(1×3)/(2×3) + 1/6 = 3/6 + 1/6
Since the denominators are now the same, add the numerators
3/6 + 1/6 = 4/6
Since 4 and 6 share a factor of 2, divide both numerator and denominator by 2 to get 2/3.

Combine the whole and fractional parts.
140 + 2/3 = 140 2/3 inches.

57.

Which type of cell in the collecting duct of the nephron contains channels for the recovery or loss of sodium and potassium?

  • Principal cell

  • Intercalated cell

  • Glomerular cell

  • Peritubular cell

Correct answer: Principal cell

Collecting ducts of the nephrons contain two cell types: principal cells, which contain channels for recovery and loss of sodium and potassium; and intercalated cells, which secrete or absorb acid or bicarbonate.

58.

Hydrophilic hormones pass their messages to their target cells by which process?

  • By activating a second messenger inside the cell

  • By enlisting the help of nearby cells to transmit their message for them

  • By activating nearby nerves to release neurotransmitters

  • By activating a G protein on the cell surface

Correct answer: By activating a second messenger inside the cell

Hydrophilic hormones cannot diffuse through a target cell membrane, which is made of a hydrophobic lipid bilayer. Instead, hydrophilic hormones bind to a receptor on the cell surface, which transfers the message to a molecule on the inside of the cell called a second messenger (the hormone itself is referred to as the first messenger), which initiates a signaling cascade in the cell. 

G protein is an intracellular protein that takes part in the signaling cascade.

59.

3(x - 4) = 18

Divide by 3.
3(x - 4) = 18
x - 4 = 18/3 = 6

Solve for x.
x - 4 = 6
Add 4 to each side
 x = 6 + 4 = 10
