TEAS Test 7 science Questions

Question 1 of 5

When baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), what type of reaction occurs?

Correct Answer: B

Rationale: When baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), a double displacement reaction occurs. In this reaction, the positive ions in baking soda switch places with the positive ions in vinegar to form water, carbon dioxide, and a salt. Combustion involves a reaction with oxygen to produce heat and light energy. Decomposition is the breakdown of a compound into simpler substances, which is not the case in the given reaction. Synthesis is the combination of substances to form a more complex compound, which is also not the type of reaction observed when baking soda and vinegar react.

Question 2 of 5

What is the purpose of genetic counseling?

Correct Answer: C

Rationale: The purpose of genetic counseling is to provide information and support to individuals and families with genetic risks. Genetic counselors aim to explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support to help individuals make informed decisions regarding their genetic health. Choice A is incorrect because genetic counseling is not focused on treatment but rather on providing information and support. Choice B is incorrect as genetic counselors do not primarily diagnose genetic diseases in newborns but rather provide guidance and support based on existing diagnoses. Choice D is not the purpose of genetic counseling; genetic counselors do not collect DNA samples for research purposes but instead focus on assisting individuals and families in understanding and managing their genetic risks.

Question 3 of 5

Which element shares the same group (family) on the periodic table with helium (He)?

Correct Answer: A

Rationale: Neon (Ne) shares the same group (family) on the periodic table with helium (He). Both helium and neon belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells, making them chemically inert. Boron (B), Carbon (C), and Oxygen (O) are not in the same group as helium. Boron is in Group 13, Carbon is in Group 14, and Oxygen is in Group 16 on the periodic table.

Question 4 of 5

When two cars with different masses collide head-on, which car experiences a greater change in momentum?

Correct Answer: C

Rationale: In a head-on collision between two cars, the law of conservation of momentum states that the total momentum of the isolated system remains constant before and after the collision. The change in momentum of one car is equal in magnitude but opposite in direction to the change in momentum of the other car. As a result, both cars experience the same change in momentum during the collision. Choice A is incorrect because the change in momentum is the same for both cars due to the conservation of momentum principle. Choice B is incorrect as the smaller mass car does not experience a greater change in momentum. Choice D is incorrect as the initial velocities of the cars do not determine which car experiences a greater change in momentum; it is solely dependent on the masses of the colliding cars.

Question 5 of 5

Which condition is commonly associated with frequent, painful urination?

Correct Answer: D

Rationale: Frequent, painful urination can be indicative of various conditions. Diabetes may cause increased urination due to high blood sugar levels, UTIs can lead to pain and frequent urination, and kidney stones can also result in painful urination. Therefore, all of the options (A, B, and C) are correct in this scenario, making option D, 'All of the above,' the correct answer. Option D encompasses all the conditions commonly associated with frequent, painful urination, making it the most comprehensive and accurate choice.
