TEAS Test 7 science quizlet

1. What is a characteristic property of acids?

Correct answer: B

Rationale: The correct characteristic property of acids is a sour taste. Acids release hydrogen ions when dissolved in water, giving them a sour taste. Bitter taste is a property associated with bases, not acids. Slippery feel is a characteristic property of bases, due to their soap-like nature. Sweet taste does not accurately describe the characteristic property of acids, as they are known for their sour taste.

2. Based on the results that were stated, what would be a logical reason for some of the plants dying with the salt solution?

Correct answer: A

Rationale: The most logical reason for some of the plants dying with the salt solution could be that salt caused the plants to begin to dry up, leading to their death. Excessive salt can disrupt the osmotic balance within plants, causing dehydration and ultimately death. Salt can create a hypertonic environment, drawing water out of plant cells and causing wilting and damage. Therefore, it is reasonable to assume that the presence of salt could have dried out some of the plants and caused them to die. Choices B and C are incorrect as the scenario presented indicates that the salt had a negative impact on the plants, causing some to die. Choice D is also incorrect as there is a valid reason provided for the plants dying due to the salt solution.

3. Which organ produces bile to aid in digestion?

Correct answer: B

Rationale: The correct answer is B: Liver. The liver produces bile, which is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The pancreas secretes digestive enzymes, not bile. The gallbladder stores bile but does not produce it. The stomach produces gastric juices, not bile, to aid in digestion.

4. Which type of waves travel by causing particles in the medium to vibrate parallel to the direction of wave travel?

Correct answer: B

Rationale: Longitudinal waves are waves in which particles of the medium vibrate parallel to the direction of wave travel. These waves are characterized by compressions and rarefactions in the medium, where particles move back and forth in the same direction as the wave. Transverse waves, on the other hand, cause particles to vibrate perpendicular to the direction of wave travel. Surface waves combine both longitudinal and transverse motion, making them different from pure longitudinal waves. Electromagnetic waves, unlike longitudinal and transverse waves, do not require a medium and can travel through a vacuum.

5. What does half-life refer to?

Correct answer: D

Rationale: Half-life refers to the time it takes for half of the radioactive atoms in a sample to decay. This means that after one half-life, half of the initial quantity of the radioactive substance will have decayed. Choice A is incorrect because radioactive intensity doesn't completely disappear during half-life. Choice B is incorrect as half-life doesn't refer to the number of neutrons doubling. Choice C is incorrect as half-life doesn't relate to the number of protons changing.
