TEAS Test of Essential Academic Skills TEAS-SECTION-2 Questions & Answers

• Question 71:

  For a given mass and constant temperature, an inverse relationship exists between the volume and pressure of a gas.

  Which of the answer choices provided best defines the following statement?

  A. Stefan-Boltzmann Law

  B. Ideal Gas Law

  C. Boyle's Law

  D. Charles' Law

  Correct Answer: C

  Boyle's law states that for a constant mass and temperature, pressure and volume are related inversely to

  one another:

  PV = c, where c = constant.

• Question 72:

  The rate of a chemical reaction depends on all of the following except __________.

  A. amount of mass lost

  B. presence of catalysts

  C. temperature

  D. surface area

  Correct Answer: A

  The rate at which a chemical reaction occurs does not depend on the amount of mass lost, since the law of conservation of mass (or matter) states that in a chemical reaction there is no loss of mass.

• Question 73:

  When does the nuclear division of somatic cells take place during cellular reproduction?

  A. mitosis

  B. meiosis

  C. cytokinesis

  D. interphase

  Correct Answer: A

  The nuclear division of somatic cells takes place during mitosis.

• Question 74:

  Which group of major parts and organs make up the immune system?

  A. nose, trachea, bronchial tubes, lungs, alveolus, and diaphragm

  B. heart, veins, arteries, and capillaries

  C. brain, spinal cord, and nerve cells

  D. lymphatic system, spleen, tonsils, thymus, and bone marrow

  Correct Answer: D

  The immune system consists of the lymphatic system, spleen, tonsils, thymus and bone marrow.

• Question 75:

  What are groups of cells that perform the same function called?

  A. molecules

  B. organs

  C. plastids

  D. tissues

  Correct Answer: D

  Groups of cells that perform the same function are called tissues.

• Question 76:

  

  What is the possibility that the offspring produced will have brown eyes? B = alleles for brown eyes; g = alleles for green eyes

  A. 100%

  B. 75%

  C. 50%

  D. 25%

  Correct Answer: B

  Dominant genes are always expressed when both alleles are dominant (BB) or when one is dominant and

  one is recessive (Bg).

  In this case, 3/4 or 75% will have brown eyes.

• Question 77:

  

  Which word describes the allele for green eyes?

  B = alleles for brown eyes; g = alleles for green eyes

  A. homozygous

  B. dominant

  C. heterozygous

  D. recessive

  Correct Answer: D

  Recessive alleles are represented by lower case letters, while dominant alleles are represented by upper case letters.

• Question 78:

  What is the longest phase of the cell cycle?

  A. mitosis

  B. cytokinesis

  C. interphase

  D. metaphase

  Correct Answer: C

  Interphase is the period when the DNA is replicated (or when the chromosomes are replicated) and is the longest part of the cell cycle.

• Question 79:

  If a cell is placed in a hypertonic solution, what will happen to the cell?

  A. It will swell.

  B. It will shrink.

  C. It does not affect the cell.

  D. It will stay the same.

  Correct Answer: B

  A hypertonic solution is a solution with a higher particle concentration than in the cell, and consequently lower water content than in the cell. Water moves from the cell to the solution, causing the cell to experience water loss and shrink.

• Question 80:

  Which of the following correctly lists the cellular hierarchy from the simplest to the most complex structure?

  A. organ system, organism, organ, tissue, cell

  B. cell, tissue, organ, organ system, organism

  C. tissue, cell, organ, organ system, organism

  D. organism, organ system, organ, tissue, cell

  Correct Answer: B

  The cellular hierarchy starts with the cell, the simplest structure, and progresses to organisms, the most complex structures.
