Science TEAS Practice Test Questions
Question 1 of 5
Which of the following best describes the statement: 'This flower is dead; someone must have forgotten to water it'?
Correct Answer: C
Rationale: The correct answer is C: An inference. This is because the statement "someone must have forgotten to water it" is not a direct observation but a conclusion drawn based on the observed condition of the dead flower. In making this statement, the speaker is connecting the lack of water to the flower being dead, which requires logical reasoning. A: A classification - This choice does not apply as the statement does not categorize or group anything. B: An observation - While the initial part of the statement is an observation (the flower is dead), the second part goes beyond just stating what is observed to drawing a conclusion based on that observation. D: A collection - This choice does not make sense in this context as the statement does not involve gathering or assembling items.
Question 2 of 5
Which type of cell secretes antibodies?
Correct Answer: D
Rationale: The correct answer is D: Plasma cells. Plasma cells are a type of white blood cell that produces and secretes antibodies, which are essential for the immune response. Plasma cells are specifically designed to produce antibodies to fight off infections. Bacterial cells (choice A) and viral cells (choice B) do not secrete antibodies as they are pathogens. Lymph cells (choice C) are a general term for various types of white blood cells, including plasma cells, but not all lymph cells secrete antibodies. Plasma cells, on the other hand, are specialized for antibody production, making choice D the correct answer.
Question 3 of 5
When a biologist describes the physical and visible expression of a genetic trait, which of the following is being referred to?
Correct Answer: A
Rationale: The correct answer is A: Phenotype. Phenotype refers to the physical and visible expression of a genetic trait. It includes observable characteristics like eye color, height, and hair texture. This is different from genotype, which represents the genetic makeup of an organism. Allele refers to different forms of a gene, and gamete is a reproductive cell. Thus, in this context, phenotype best describes the physical manifestation of a genetic trait, making it the correct answer.
Question 4 of 5
Which of the following organs functions as both an endocrine and exocrine gland?
Correct Answer: C
Rationale: The correct answer is C: The pancreas. The pancreas functions as both an endocrine and exocrine gland. It secretes digestive enzymes (exocrine function) into the small intestine and produces hormones such as insulin and glucagon (endocrine function). This dual role allows the pancreas to regulate both digestion and blood sugar levels. Incorrect Answers: A: The kidney - Functions mainly in filtration and regulation of fluid balance, not as an endocrine/exocrine gland. B: The spleen - Primarily involved in immune function and blood filtration, not as an endocrine/exocrine gland. D: The stomach - Secretes digestive enzymes, but does not have a significant endocrine function like the pancreas.
Question 5 of 5
Which of the following is not a type of muscle tissue?
Correct Answer: D
Rationale: The correct answer is D: Adipose. Adipose tissue is a type of connective tissue that stores fat, not a type of muscle tissue. Skeletal, smooth, and cardiac tissues are the three main types of muscle tissue. Skeletal muscles are attached to bones, smooth muscles are found in organs and blood vessels, and cardiac muscles are specific to the heart. Adipose tissue does not have the contractile properties of muscle tissue, making it the correct choice.
