TEAS Test 7 science Questions

Question 1 of 5

Which form of energy is associated with the motion of an object?

Correct Answer: A

Rationale: Kinetic energy is the form of energy associated with the motion of an object. When an object is in motion, it possesses kinetic energy due to its movement. Potential energy, on the other hand, is stored energy that an object has due to its position or condition. Thermal energy is related to heat, while electrical energy is associated with the flow of electric charge. In this case, the correct answer is kinetic energy as it directly correlates with the motion of an object.

Question 2 of 5

Edema, characterized by swelling due to fluid buildup, can be a sign of:

Correct Answer: D

Rationale: Edema is the swelling caused by fluid retention in the body tissues. It can indicate various underlying conditions. Heart failure can lead to fluid buildup due to the heart's ineffective pumping. Liver disease can cause edema by reducing protein production, leading to fluid leakage into tissues. Dysfunction of the lymphatic system can impair fluid drainage, contributing to edema. Therefore, all of the above conditions can manifest with edema, making the correct answer 'All of the above.' Choices A, B, and C are all valid causes of edema, making them incorrect when considered individually. Selecting 'All of the above' encompasses all the possible causes of edema.

Question 3 of 5

Which of the following is a common property of both acids and bases?

Correct Answer: D

Rationale: The correct answer is D. Both acids and bases can conduct electricity when dissolved in water. Acids ionize in water to produce H+ ions, which can carry an electric current, while bases ionize to produce OH- ions, which also conduct electricity. The other options are not common properties of both acids and bases. Reacting with metals to produce hydrogen gas is characteristic of acids, tasting sour is a property of acids, and turning blue litmus paper red is a property of bases, not a common property shared by both.

Question 4 of 5

Which property of matter refers to the force of gravity acting on an object?

Correct Answer: B

Rationale: Weight is the property of matter that refers to the force of gravity acting on an object. Mass is the amount of matter in an object, not affected by gravity. Density is the mass per unit volume of a substance, not directly related to gravity. Volume is the amount of space that an object occupies, not a measure of gravity's force.

Question 5 of 5

What is the process of copying DNA called?

Correct Answer: C

Rationale: The correct answer is C, Replication. Replication is the process of making an identical copy of DNA. During replication, the DNA double helix unwinds, and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules. Transcription (choice A) involves the synthesis of mRNA from a DNA template, not the direct copying of DNA. Translation (choice B) is the process of converting mRNA into a sequence of amino acids to form a protein, not copying DNA. Mutation (choice D) refers to changes in the DNA sequence, which can occur during replication but is not the process of copying DNA itself.
