Practice Science TEAS Test

1. Which cavity is primarily lined by the peritoneum?

Correct answer: A

Rationale: The correct answer is 'Abdominal.' The peritoneum primarily lines the abdominal cavity, providing support and protection to abdominal organs. It is a serous membrane that covers the abdominal organs and the abdominal wall, aiding in their function and protection. Choice B, 'Dorsal,' is incorrect because the peritoneum does not primarily line the dorsal cavity. Choice C, 'Ventral,' is incorrect as the peritoneum is not primarily associated with the ventral cavity. Choice D, 'Thoracic,' is incorrect because the peritoneum primarily lines the abdominal cavity and is not primarily found in the thoracic cavity.

2. What is the process by which a solid changes directly into a liquid?

Correct answer: A

Rationale: The correct answer is A: Melting. Melting is the process through which a solid substance changes directly into a liquid. Choice B, Condensation, is the transition from gas to liquid. Choice C, Sublimation, refers to the direct change from solid to gas. Choice D, Deposition, is the direct transition from gas to solid, not from solid to liquid as in the question.

3. Which property of a substance refers to its ability to undergo a chemical change and form new substances?

Correct answer: C

Rationale: Reactivity is the property of a substance that describes its ability to undergo a chemical change and form new substances through chemical reactions. Density, mass, and volume are physical properties of a substance and do not directly relate to its ability to undergo chemical changes. Density is the mass of a substance per unit volume, mass is the amount of matter present, and volume is the amount of space occupied by the substance. Reactivity specifically deals with how likely a substance is to engage in chemical reactions. Therefore, the correct answer is C - Reactivity.

4. Which of the following best describes eosinophils?

Correct answer: C

Rationale: Eosinophils are best described as a type of granulocyte found under mucous membranes that defends against multicellular parasites. They release toxic substances to combat parasitic infections and play a significant role in allergic reactions and asthma. Histamine secretion to stimulate inflammation is more characteristic of basophils, while high phagocytic activity and aggressiveness are features of neutrophils, not eosinophils. Describing eosinophils as the most abundant type of white blood cell that secretes toxic substances to pathogens is inaccurate since eosinophils specifically target multicellular parasites, not a broad range of pathogens.

5. What is one feature that both prokaryotes and eukaryotes have in common?

Correct answer: A

Rationale: The correct answer is A: A plasma membrane. Both prokaryotes and eukaryotes share the characteristic of having a plasma membrane that surrounds the cell. While eukaryotes also possess a nucleus enclosed by a membrane and various organelles, prokaryotes lack a nucleus and membrane-bound organelles. The plasma membrane, however, is a universal feature found in all cells, regardless of their classification as prokaryotic or eukaryotic. Choice B is incorrect because only eukaryotes have a nucleus enclosed by a membrane. Choice C is incorrect because prokaryotes have limited organelles compared to eukaryotes. Choice D is incorrect as a nucleoid is a region in prokaryotic cells where the genetic material is located, not a common feature shared with eukaryotes.
