TEAS 7 science practice questions

1. When a person pushes a box across the floor, which of the following forces is NOT doing work?

Correct answer: B

Rationale: The normal force from the floor is perpendicular to the direction of motion of the box, so it does not contribute to the work being done. Work is only done by forces acting in the direction of motion of an object. In this case, the normal force is acting at a right angle to the motion, hence it does not perform any work on the box. The person's pushing force, the gravitational force, and the frictional force are all acting in the direction of motion of the box, so they contribute to the work being done in moving the box across the floor.

2. What are the components of the male external genitalia and their functions?

Correct answer: C

Rationale: The correct answer is C. The penis is responsible for delivering sperm to the female reproductive tract during sexual intercourse. The scrotum is not involved in producing sperm but rather protects and regulates the temperature of the testes, which is essential for sperm production. The prostate gland is involved in producing seminal fluid, not sperm. The urethra serves the purpose of conducting urine out of the body and also acts as a passage for semen during ejaculation.

3. What is the role of the spindle apparatus in cell division?

Correct answer: B

Rationale: The spindle apparatus, composed of microtubules, plays a crucial role in cell division (mitosis and meiosis) by ensuring proper chromosome separation and distribution to opposite poles of the cell. This segregation is vital for creating two genetically identical daughter cells in mitosis or four haploid daughter cells in meiosis. Choice A is incorrect because the separation of sister chromatids is specifically carried out by kinetochore fibers within the spindle apparatus. Choice C is inaccurate as the formation of a new nuclear envelope occurs post chromosome segregation. Choice D is incorrect as DNA synthesis does not occur within the spindle apparatus; it takes place during the S phase of the cell cycle.

4. If a doctor diagnoses a patient with an impaired posterior pituitary gland, which of the following symptoms related to kidney function does the patient display?

Correct answer: D

Rationale: When the posterior pituitary gland is impaired, there is decreased secretion of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water reabsorption by the kidneys. A deficiency of ADH leads to the inability of the kidneys to concentrate urine, resulting in the production of dilute urine. Therefore, 'Concentrated urine' is the correct symptom associated with impaired posterior pituitary gland. Choices A, B, and C are incorrect. Thirst is more commonly associated with diabetes insipidus, tiredness could be a general symptom but not specifically related to kidney function, and weight gain is not a typical symptom of impaired posterior pituitary gland affecting kidney function.

5. What characteristic unites all organisms in the kingdom Animalia?

Correct answer: A

Rationale: A) Multicellularity and heterotrophy: This is the correct answer because all organisms in the kingdom Animalia are multicellular (composed of multiple cells) and exhibit heterotrophy (obtain nutrients by consuming other organisms). B) Unicellular nature: This is incorrect because organisms in the kingdom Animalia are multicellular, not unicellular. C) Photosynthesis: This is incorrect because organisms in the kingdom Animalia do not perform photosynthesis; they are heterotrophs that obtain nutrients by consuming other organisms. D) Cell walls made of chitin: This is incorrect because organisms in the kingdom Animalia do not have cell walls made of chitin. Chitin is a structural polysaccharide found in the cell walls of fungi, not animals.
