TEAS Practice Questions

The correct answer is D (Sofia's observations of Ruby and Oscar's interactions with their chicks and their feeding habits).

The passage describes Sofia's discovery of a family of birds nesting on her balcony and her subsequent observations of their activities. Sofia's documentation of the birds caring for their young and feeding on seeds indicates that the upcoming paragraphs will likely detail her observations of Ruby and Oscar's interactions with their chicks and their feeding habits. Option D is correct because it aligns with the information provided and is a reasonable prediction based on the passage content.

The correct answer is B (To entertain readers with thrilling tales of adventure and daring).

Answer (B) is correct because the passage introduces Captain Redbeard in the context of thrilling tales of adventure and daring. The description of Redbeard as a notorious pirate who terrorized the high seas suggests that the author's purpose is to entertain readers with exciting and adventurous stories.

Answer (A) is incorrect because while the challenges of life as a pirate are implied, they are not the primary focus of the passage.

Answer (C) is incorrect because although the passage mentions maritime trade, it does not delve into the historical context in detail.

Answer (D) is incorrect because while the economic impact of piracy is mentioned (Redbeard amassing a vast fortune), it is not the main purpose of introducing Captain Redbeard in the passage.

The correct answer is C (Rising global temperatures contribute to the vulnerability of coral reefs).

The passage discusses how rising global temperatures contribute to coral bleaching and the vulnerability of coral reefs. It explains that warmer ocean waters cause coral bleaching, which weakens coral reefs. Therefore, option C, which states that rising global temperatures contribute to the vulnerability of coral reefs, is the correct conclusion drawn from the passage.

Answer (A) is incorrect because, according to the passage, coral bleaching is not primarily caused by disease outbreaks.

Answer (B) is incorrect because ocean acidification inhibits, rather than enhances, coral growth and reproduction, as mentioned in the passage.

Answer (D) is incorrect because the passage suggests that coral reefs are vulnerable rather than resilient to changes in their environment caused by climate change.

The correct answer is C (480).

To solve this problem, we can break it down into calculating points from judges' compliments and family compliments separately, then summing them up.

Judges' Compliments:
Elena received 9 compliments from the judges. For every 3 compliments from the judges, she earns 150 points. To find out how many sets of 3 compliments fit into 9, divide 9 by 3:
9 / 3 = 3 sets
Now, multiply the number of sets by the points per set:
3 sets * 150 points/set = 450 points

Family Compliments:
Elena received 18 compliments from her family. For every 45 compliments from family members, she earns 30 points. To find out how many sets of 45 compliments fit into 18, divide 18 by 45:
18 / 45 = 0.4 sets (since 18 is less than 45, she only gets 30 points)
Now, multiply the number of sets by the points per set:
0.4 sets * 30 points/set = 12 points

Total Points:
Add the points from judges' compliments and family compliments together:
450 points + 30 points = 480 points

Therefore, Elena Starlight obtained 480 points in total.

The correct answer is D (The house never lost value over the ten years).

Each point on the graph is either equal to or greater than the previous point. Therefore, the house never reduced in value over the ten years.

Answer (A) is incorrect because there is a positive relationship in the graph. The points are going upwards.

Answer (B) is incorrect because eight years after purchase, the value of the house was $500,000 and not $500.

Answer (C) is incorrect because the house's value began at $350,000. Doubling in value would mean the house would be worth $700,000 after 10 years. In fact, it is worth less than $600,000.

The correct answer is A ( Patella).

A sesamoid bone is a type of bone that develops within a tendon, often near joints. The patella, commonly known as the kneecap, is a prominent example of a sesamoid bone located in the tendon of the quadriceps femoris muscle. It functions to protect the knee joint and improve the mechanical advantage of the muscle by increasing the angle of pull. Options B, C, and D are incorrect as they are not classified as sesamoid bones: the scapula is a shoulder blade (flat bone), the radius is a forearm bone (long bone), and the mandible is the jawbone (irregular bone).

The correct answer is C (Duplication of chromosomal material).

Duplication of chromosomal material, or DNA replication, is a process that occurs in both mitosis and meiosis. Before cells divide, whether in mitosis or meiosis, the DNA within the cell must replicate to ensure that each daughter cell receives a full set of genetic information. This process occurs during the interphase preceding both mitosis and meiosis.

Option (A) Crossing over between homologous chromosomes is a process unique to meiosis, where homologous chromosomes exchange genetic material during prophase I.

Option (B) Division of a diploid cell into two haploid daughter cells occurs specifically in meiosis II, where haploid cells resulting from meiosis I divide to form four haploid daughter cells.

Option (D) Formation of gametes specifically refers to meiosis, where diploid cells undergo two divisions to produce haploid gametes (sperm or eggs).

Therefore, option (C) Duplication of chromosomal material is the correct answer as it is a process common to both mitosis and meiosis, ensuring genetic fidelity in daughter cells.

The correct answer is D (There are two intermediates and three transition states in the overall reaction).

The graph depicts the reaction pathway from reactant A to product D. Reactant A is less stable than product D, as indicated by its lower position on the y-axis. The peaks represent activated complexes, which are less stable than both the reactants and products. Points B and C denote transition states, which have lower energy than the activated complexes but are less stable than the products in terms of energy expenditure.

Specifically, an activated complex forms transiently during collisions and is entirely unstable, capable of either dissociating back into reactants or forming products. Transition states are characterized by the highest energies along the reaction profile, while intermediates are relatively stable species involved in the reaction mechanism but are neither reactants nor appear in the reaction rate law. According to the profile, the reaction mechanism involves three transition states (points of maximum energy) and two intermediates (points B and C).

Thus, option (D) is correct. Activation energy represents the minimum collision energy required for a chemical reaction to initiate, acting as a barrier separating reactants from products. Only a fraction of colliding molecules possess adequate kinetic energy to surmount this barrier. In a reaction profile, the activation energy for a forward reaction equals the energy difference between an activated complex and a reactant.

Option (A) is incorrect because the enthalpy change (ΔH) of the reaction reflects the energy difference between products and reactants, indicating an exothermic reaction (ΔH < 0) due to lower product energy. Option (B) is incorrect because the fastest step in the reaction pathway is C → D, not B → C, owing to its lower activation energy. Option (C) is incorrect because the rate-determining step in the overall reaction is A → B, not B → C, due to its higher activation energy.

The correct answer is A (Graduated cylinder).

A graduated cylinder is suitable for measuring and transferring larger volumes of liquids with reasonable accuracy. It allows the student to measure out exactly 5 milliliters of the solution from the original test tube containing 50 milliliters. This tool is appropriate for this task because it provides graduated markings that indicate various volumes.

Answer B) Beaker is incorrect because while it can hold liquids, it does not provide the precise measurements needed for transferring exactly 5 milliliters.

Answer C) Volumetric pipette is incorrect because it is more suitable for transferring very precise, small volumes of liquids, typically less than 5 milliliters.

Answer D) Stopwatch is incorrect because it is used to measure time and is not relevant to liquid measurement or transfer tasks in the laboratory.

The correct answer is B ("Where are you going?" she asked, "without your coat?").

When a dialogue sentence ends with a question mark, the question mark should be placed inside the quotation marks. A comma must follow the quotation marks before the dialogue tag. The continuation of the dialogue starts with a lowercase letter if it is part of the same sentence. The only answer that follows these rules is answer (B).

The correct answer is A (obedient).

The word “recalcitrant” means “resisting authority or control; not obedient or compliant.” The word “obedient” means “complying or willing to comply with orders or requests; submissive to another's will.” Therefore, the words “recalcitrant” and “obedient” have opposite meanings, which makes them antonyms, and answer A is correct.

Answers B, C, and D are incorrect because the words “defiant,” “stubborn,” and “unyielding” all have similar meanings to the word “recalcitrant” and not opposite meanings.

The correct answer is B (whom).

The pronoun functions as the object of the sentence and should, therefore, be "whom."

Answer (A) is incorrect because the pronoun "who" functions as the subject of the sentence, i.e., who performs the action. "Whom," on the other hand, should be used as an object and not a subject. Note that in the relevant clause, "we" perform the action on Mr. Johnson and not the other way around. Therefore, Mr. Johnson is the object and not the subject, and thus, the correct pronoun is "whom" and not "who."

Answer (C) is incorrect because the pronoun "which" refers to things rather than people.

Answer (D) is incorrect because the pronoun "that" refers to things rather than people.
