Practice English TEAS TEST

1. Who is probably the oldest person in my family?

A. My Uncle Johan
B. The oldest person
C. The oldest person in my family
D. Family

Correct answer: C

Rationale: The correct answer is 'C: The oldest person in my family.' The complete subject of the sentence is 'The oldest person in my family,' which includes all the words that describe who or what the sentence is about. Choices A, B, and D are incorrect because they do not form a complete subject that accurately represents who the sentence is referring to in the context of the family relationship.

2. What are the four main types of macromolecules that are essential for life?

A. Carbohydrates, lipids, proteins, and nucleic acids
B. Carbohydrates, proteins, fats, and vitamins
C. Minerals, vitamins, proteins, and fats
D. Carbohydrates, lipids, proteins, and hormones

Correct answer: A

Rationale: The correct answer is A: Carbohydrates, lipids, proteins, and nucleic acids. These four types of macromolecules are essential for life as they serve crucial roles in various cellular processes. Carbohydrates are the primary energy source for cells and provide structural support. Lipids function as energy storage molecules and are essential components of cell membranes. Proteins have diverse functions in cellular processes, acting as enzymes, structural components, and more. Nucleic acids, like DNA and RNA, carry genetic information and are crucial for protein synthesis. Choices B, C, and D are incorrect because they include elements like fats, vitamins, minerals, and hormones, which are not the main types of macromolecules essential for life.

3. Which of the following punctuation marks is used incorrectly in the sentence? "Otto, somewhat abruptly, got up out of his chair, and just like that, headed into the next room."

A. The comma after "somewhat"
B. The comma after "Otto"
C. The semicolon after "that"
D. The comma after "chair"

Correct answer: C

Rationale: The semicolon after "that" is used incorrectly; a comma should be used instead. Semicolons are typically used to join two independent clauses without a conjunction. In this sentence, the phrase "just like that" is not an independent clause, so a comma is more appropriate for separating it from the rest of the sentence. Choices A, B, and D all use commas correctly within the sentence.

4. How do killer T cells recognize infected cells?

A. The B cells flag the infected cells with amino acids.
B. Tiny bits of the virus's RNA are left around the cell.
C. Macrophages show up to help consume the infected cell.
D. The T cells have receptors that recognize the proteins the virus leaves on the surface of the cell.

Correct answer: D

Rationale: Killer T cells recognize infected cells by detecting viral proteins displayed on the surface of these cells. The T cells possess receptors specifically designed to identify these viral proteins, allowing them to target and eliminate the infected cells. Choice A is incorrect because B cells are not directly involved in the recognition process of infected cells by killer T cells. Choice B is incorrect because tiny bits of the virus's RNA being left around the cell is not how killer T cells primarily recognize infected cells. Choice C is incorrect because while macrophages play a role in immune responses, they do not directly assist in the recognition of infected cells by killer T cells.

5. What are the components of the male internal genitalia and their functions?

A. Prostate gland: produces hormones
B. Testes: produce sperm and testosterone
C. Epididymis: stores and matures sperm
D. Urethra: conducts urine and semen out of the body

Correct answer: B

Rationale: The testes play a crucial role in male reproduction by producing sperm and testosterone. Sperm production is essential for fertility, while testosterone is responsible for the development of secondary sexual characteristics. The epididymis functions to store and mature sperm, allowing them to become motile. The prostate gland, not listed among the choices, secretes fluid that nourishes and protects sperm. The urethra serves the purpose of conducting both urine and semen out of the body, enabling the excretion of waste and reproductive fluids.
