1. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?

• A. Gravitational force
• B. Normal force from the ground
• C. Air resistance
• D. The force of throwing

Correct answer: C

Rationale: During the flight of the object, the only force that acts horizontally on the object is air resistance. Air resistance opposes the motion of the object through the air and acts in the direction opposite to the object's velocity. Gravitational force acts vertically downward, influencing the object's weight and vertical motion. The normal force from the ground acts perpendicular to the ground to support the object's weight. The force of throwing initially imparts velocity to the object at an angle, but it does not act horizontally throughout the flight.

2. Which type of reasoning has the FBI agent used?

• A. Deductive Reasoning
• B. Conductive Reasoning
• C. Quantitative Reasoning
• D. Inductive Reasoning

Correct answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing general conclusions from specific observations or instances. In this case, the FBI agent is creating a theory based on observations of specific cases rather than applying a general rule to a specific situation (which would be deductive reasoning). Conductive reasoning is not a recognized type of reasoning, and quantitative reasoning involves interpreting and analyzing quantitative information.

3. How are genetic markers utilized in paternity testing?

• A. They identify unique sequences in the father's DNA present in the child.
• B. They analyze the presence or absence of specific alleles for certain genes.
• C. They compare the child's blood type to the parents' blood types.
• D. They measure the child's physical resemblance to the father.

Correct answer: B

Rationale: Genetic markers are specific DNA sequences that can vary among individuals. In paternity testing, genetic markers are used to compare the DNA of the child with that of the alleged father. By analyzing the presence or absence of specific alleles (different forms of a gene) at these genetic markers, scientists can determine the likelihood of paternity. This method is more accurate and reliable than comparing blood types (choice C) or physical resemblance (choice D) as genetic markers provide a direct comparison of DNA sequences between individuals. Therefore, option B is the correct choice as it accurately describes the use of genetic markers in paternity testing.

4. Which is the correct order of formed elements in blood from smallest to largest cell size?

• A. Erythrocytes, thrombocytes, and leukocytes
• B. Thrombocytes, leukocytes, and erythrocytes
• C. Thrombocytes, erythrocytes, and leukocytes
• D. Leukocytes, erythrocytes, and thrombocytes

Correct answer: C

Rationale: The correct order of formed elements in blood from smallest to largest cell size is thrombocytes (platelets), erythrocytes (red blood cells), and leukocytes (white blood cells), making choice C the correct answer. Thrombocytes are the smallest, followed by erythrocytes, and then leukocytes. Choices A, B, and D are incorrect because they do not follow the correct order of cell size in blood formed elements.

5. Which of the following best describes the statement 'This flower is dead; someone must have forgotten to water it'?

• A. A classification
• B. An observation
• C. An inference
• D. A collection

Correct answer: C

Rationale: The correct answer is 'C: An inference.' An inference is a conclusion reached based on evidence and reasoning. In this statement, the conclusion that someone must have forgotten to water the flower is drawn from the evidence that the flower is dead. Choice A, 'A classification,' is incorrect because the statement does not involve categorizing or grouping. Choice B, 'An observation,' is incorrect as the statement goes beyond just stating a fact and makes a conclusion. Choice D, 'A collection,' is unrelated to the process of drawing a conclusion based on the given evidence.
