1. In which regions of the digestive system is amylase produced?

• A. pancreas and salivary glands
• B. gall bladder and salivary glands
• C. gall bladder and liver
• D. pancreas and liver

Correct answer: A

Rationale: Amylase is an enzyme that breaks down carbohydrates into smaller sugars. It is produced in the pancreas and salivary glands. The salivary glands release amylase into the mouth during chewing, where it initiates the breakdown of carbohydrates. The pancreas also secretes amylase into the small intestine to further assist in carbohydrate digestion. Choices B, C, and D are incorrect as the gall bladder does not produce amylase, and the liver's primary function is not the production of amylase for carbohydrate breakdown.

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. Which of the following is NOT part of the circulatory system?

• A. Kidneys
• B. Heart
• C. Blood
• D. Blood vessels

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are part of the urinary system, responsible for filtering waste and maintaining fluid balance in the body. In the circulatory system, the heart pumps blood, blood carries oxygen and nutrients, and blood vessels transport blood throughout the body. Choices B, C, and D are all components of the circulatory system, making the kidneys the correct choice as it belongs to the urinary system.

4. Which part of the neuron is responsible for transmitting signals away from the cell body and toward other neurons or muscles?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Myelin sheath

Correct answer: A

Rationale: The axon is the part of the neuron responsible for transmitting signals away from the cell body and toward other neurons or muscles. It is a long, slender projection covered by the myelin sheath, which speeds up signal transmission. Dendrites, on the other hand, receive signals from other neurons and transmit them toward the cell body. The synapse is the junction between two neurons where communication occurs, but it is not responsible for transmitting signals away from the cell body.

5. What step of the scientific method must come before generating a hypothesis?

• A. Collecting and organizing data.
• B. Communicating the results in a scientific journal.
• C. Conducting an experiment.
• D. Researching previous studies for background.

Correct answer: D

Rationale: The correct answer is D, 'Researching previous studies for background.' Before formulating a hypothesis, it is essential to review existing literature, studies, and information related to the topic to understand the context and identify gaps in knowledge. This step helps researchers build on existing knowledge and formulate a clear hypothesis based on the information gathered. Choices A, B, and C are incorrect because they come after the step of researching previous studies and developing a hypothesis. Collecting and organizing data, conducting an experiment, and communicating results typically follow the hypothesis generation step in the scientific method.
