John, Jack, and Jim are splitting the cost of a new Jeep evenly. If the Jeep costs $37,461, how much does Jack pay?

  • $12,487

  • $18,730.50

  • $9.365.25

  • $14,821

Correct answer: $12,487

There are three people splitting the cost, so each pays 1/3 of the total. Multiply the total by 1/3, giving 1/3×$37,461 = $12,487.

142.

Which of these consists largely of specialized lipids called phospholipids?

  • Plasma membrane

  • Cytoplasm

  • Nucleus

  • Nuclear envelope

Correct answer: Plasma membrane

The human cell is made up of three main parts:

  1. Plasma membrane: A double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
  2. Cytoplasm: Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.
  3. Nucleus: The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell.

The nuclear envelope is a double-layered membrane that encloses the contents of the nucleus during most of the cell's lifecycle. There are small holes in the nuclear membrane called nuclear pores, and these pores allow content to move in and out of the nucleus. They also connect the inner membrane with the outer membrane.

143.

In which of the following phases of matter do molecules exert little or no attraction to one another because they move at high speeds?

  • Gas

  • Solid

  • Plasma

  • Liquid

Correct answer: Gas

Gas is the phase of matter in which molecules exert little or no attraction to one another because they move at high speeds. Solid is the phase of matter in which molecules exert a strong attraction to one another, as they move slowly relative to one another. Plasma is the phase of matter that is made up of electrons and positive ions. Liquid is the phase of matter in which molecules exert moderate attractions to one another, as they move at moderate speeds.

144.

Which type of tissue does myelin work to protect?

  • Nervous

  • Cardiac

  • Muscle

  • Connective

Correct answer: Nervous

Nervous tissue makes up the structure of the brain, nerves, and spinal cord. Neurons make up the nerves and send electrical signals throughout the body. Certain specialized support cells, such as myelin, work to protect nervous tissue.

145.

Of the following choices, which is an organ of the respiratory system?

  • Larynx

  • Heart

  • Pancreas

  • Brain

Correct answer: Larynx

The respiratory system’s main function are the critical tasks of transporting oxygen into the body’s cells and moving carbon dioxide out of the body. The respiratory system includes the lungs, trachea, larynx, bronchioles, bronchi, and alveoli.

The heart is an organ of the cardiovascular (circulatory) system. The pancreas is an organ of the endocrine system. The brain is an organ of the neuromuscular system.

146.

Which option identifies a substance that would be considered an acid?

  • A substance with a pH of 4.1

  • A substance with a pH of 7.0

  • A substance with a pH of 11.9

  • A substance with a pH of 8.2

Correct answer: A substance with a pH of 4.1

A substance with a pH of 4.1 would be considered an acid, as any substance with a pH less than 7.0 is considered an acid.

A substance with a pH of 8.2 or 11.9 would be considered a base, as any substance with a pH greater than 7.0 is considered a base. A substance with a pH of 7.0 is considered neutral.

147.

Which of the following is not a principal function of the genitourinary system?

  • Nutrient absorption

  • Stabilizing water balance

  • Creating urine

  • Filtering blood

Correct answer: Nutrient absorption

Nutrient absorption is a principal function of the gastrointestinal (digestive) system, not the genitourinary system.

The genitourinary system is responsible for the excretory process. Organs in the genitourinary system include the kidneys, ureters, urinary bladder, and urethra. Excretion is a necessary function for salt and water homeostasis and getting rid of wastes.

Kidneys manufacture urine, which travels through the ureters to the urinary bladder where it is stored until excretion through the urethra. Kidneys are primarily responsible for filtering blood, creating urine, stabilizing water balance, maintaining blood pressure, and producing the active form of vitamin D. Kidneys play a vital role in maintaining blood and blood pressure.

All of the following statements are opinions except:

  • The high school football team beat their rival by ten points last year.

  • Andrea plays the flute better than Kristen does.

  • The math club has the smartest people in school.

  • She must like hamburgers because she eats them all the time.

Correct answer: The high school football team beat their rival by ten points last year.

The sentence that is not an opinion is: The high school football team beat their rival by ten points last year. Facts can be supported by specific, verifiable details. Opinions are based on assumptions and people's perception of an incident. Also, look closely at the word choices to help you determine if a statement is a fact or an opinion.

The other three statements are considered opinions, as they cannot be supported by verifiable details. Opinion-based statements generally have judgment words such as best, worst etc., within them.

Eukaryotic cells are cells that have which of the following?

  • A defined nucleus and a series of membrane-bound organelles

  • No defined nucleus and no membrane-bound organelles

  • No defined nucleus and a series of membrane-bound organelles

  • A defined nucleus and no membrane-bound organelles

Correct answer: A defined nucleus and a series of membrane-bound organelles

There are two types of cells, which are known as prokaryotic and eukaryotic.

  • Prokaryotic cells are cells that have no defined nucleus and no membrane-bound organelles. 
  • Eukaryotic cells have a defined nucleus and a series of membrane-bound organelles.

150.

Which body system integrates muscles and nerves?

  • Neuromuscular system

  • Integumentary system

  • Skeletal system

  • Cardiovascular system

Correct answer: Neuromuscular system

The neuromuscular system integrates muscles and nerves. This system affects every part of the body and is vital in controlling involuntary and voluntary movement.

The integumentary system contains organs and glands that are vital to protecting the body and regulating temperature. It refers to the largest organ: the skin. The integumentary system consists of skin, hair, nails, sebaceous glands, sudoriferous glands, and ceruminous glands.

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 cardiovascular (circulatory) system is responsible for the movement of blood and lymph around the body. This allows for nutrient distribution, waste removal, communication, and protection. The cardiovascular system includes the heart, arteries, veins, plasma, lymph, lymphocytes, leukocytes, hemoglobin, and capillaries.

151.

Which of the following are Y- or T-shaped cells that originate in bone marrow and make proteins known as antibodies?

  • B-lymphocytes

  • T-lymphocytes

  • Natural killer cells

  • Y-lymphocytes

Correct answer: B-lymphocytes

B-lymphocytes are Y- or T-shaped cells that originate in bone marrow and make proteins known as antibodies. B-lymphocytes are also known as B-cells.

T-lymphocytes, or T-cells, mature in the thymus, and they directly engulf and destroy pathogens. Natural killer cells, or NK cells, directly attack virus-infected cells. Y-lymphocytes is incorrect, because it is not a type of lymphocyte.

152.

A chemical bond in which electrons are shared in a way that stabilizes both atoms is called a/n:

  • Covalent bond

  • Ionic bond

  • Hydrogen bond

  • Electrostatic bond

Correct answer: Covalent bond

An ionic bond is formed when an atom donates or accepts one or more electrons and remains in close association with the other atom, forming two atoms with opposite charges held together by electrostatic attraction. The atom that loses an electron becomes positively charged and is called a cation. The atom that gains an electron becomes negatively charged and is called an anion. A covalent bond creates a molecule in which electrons are mutually shared between two atoms, creating a highly stable molecule. 

A hydrogen bond occurs when a hydrogen atom from one molecule is attracted to a negatively charged atom of another molecule. Hydrogen atoms are weakly positive, so the chemical bonds they create are weak bonds.

153.

Which of the following prefixes indicates hate?

  • miso-

  • mal-

  • deca-

  • circ-

Correct answer: miso-

The prefix miso- is added to a word to indicate hate. For example, misogyny means hatred of women, and misogamy means hatred of marriage.

The prefix mal- is added to a word to indicate poorly or badly. The prefix deca- is added to a word to indicate ten. The prefix circ- is added to a word to indicate around.

154.

Which of the following words is spelled correctly?

  • Derangement

  • Derangment

  • Derangeament

  • Derangmint

Correct answer: Derangement

Derangement is spelled correctly.

When adding a suffix (-ment) to a root word that ends in -e (derange), do not drop the -e if the suffix begins with a consonant. In this case, the suffix begins with the letter -m, a consonant, so the -e in the root word derange should stay. The proper spelling of the word is derangement.

155.

Rebecca can make two loaves of bread in 80 minutes. How long will it take her to make nine loaves of bread?

  • 6 hours

  • 9 hours

  • 7 hours

  • 8 hours

Correct answer: 6 hours

Write a proportion.
Since the ratio of loves to minutes must be constant, the proportion must be 2:80 = 9:x.

Convert the proportion to a fraction equation.
The above proportion is equivalent to 2/80 = 9/x.

Cross-multiply and solve for x.
Cross-multiplying eliminates the denominators and gives the equation 2x = 80⋅9 = 720, so x =720/2 = 360 minutes.

Conver x to hours.
Use a unit conversion fraction.
360 minutes × 1 hour/60 minutes = 6 hours.

156.

Which of the following correctly defines aberration as used in this passage?

  • deviation especially from moral standard or normal state

  • improperly forward or bold 

  • depart from or evade the truth 

  • extravagant exaggeration 

Correct answer: deviation especially from moral standard or normal state

Aberration is deviation especially from moral standard or normal state.

Improperly forward or bold is impudent. Depart from or evade the truth is prevaricate. Extravagant exaggeration is hyperbole.

Preeclampsia, a high blood pressure condition in pregnancy, is found to be associated with rapid weight gain. As a result, doctors begin to advise their patients to restrict their weight gain. However, it is later discovered that preeclampsia is the cause, not the effect, of rapid weight gain. This cause-effect relationship is an example of: 

  • Reverse causation

  • Concurrent causes

  • Probable causality

  • Chain reaction

Correct answer: Reverse causation

Reverse causation is an invalid form of reasoning that reverses cause and effect. In this example, the doctors incorrectly concluded that the effect (rapid weight gain) was the cause (preeclampsia).

Concurrent causes describes a situation in which there may be more than one significant cause for an effect. Probability causality estimates the chances that a specific effect is due to a specific cause. A chain reaction describes a series of causes and effects.

158.

Which of the following has correct pronoun-antecedent agreement?

  • Over yonder there are pastures with a lot of green grass. The cows love it.

  • The girl and his mother liked going to the theater, as the escape from reality for a few moments was always welcome.

  • Marisa loved water sports and ice sports. Their favorite was surfing.

  • We spoke with our professor for hours, but they didn’t give us the information we actually needed.

Correct answer: Over yonder there are pastures with a lot of green grass. The cows love it.

Over yonder there are pastures with a lot of green grass. The cows love it. has a couple of possible antecedents: pastures (plural), green grass (singular), or the concept pastures with a lot of green grass (singular). The singular pronoun it correctly refers to the singular antecedent green grass or pastures with a lot of green grass.

The girl and his mother liked going to the theater, as the escape from reality for a few moments was always welcome has a feminine antecedent the girl incorrectly followed by a masculine possessive pronoun his. Marisa loved water sports and ice sports. Their favorite was surfing has a singular antecedent Marisa incorrectly followed by a plural possessive pronoun their. We spoke with our professor for hours, but they didn’t give us the information we actually needed has a singular antecedent professor incorrectly followed by a plural pronoun they.

159.

Find the value of x by solving the following proportion.

21:63 = 24:x

  • 72

  • 56

  • 48

  • 12

Correct answer: 72

Convert proportion to a fraction

21/63 = 24/x

Simplify 21/63 to 1/3

1/3 = 24/x

Multiply both sides by x

1/3⋅x = 24

Simplify 1/3⋅x to x/3

x/3 = 24

Multiply both sides by 3

x = 72
