1. The site of chemical communication in the brain is the ________.

• A. neuron
• B. synapse
• C. axon
• D. dendrite

Correct answer: B

Rationale: The synapse is the correct answer. It is the site where communication between neurons occurs through the release and reception of neurotransmitters. Choice A, neuron, is incorrect as it is the cell itself rather than a specific site of communication. Choice C, axon, is also incorrect as it is a part of the neuron that transmits signals away from the cell body. Choice D, dendrite, is not the correct answer either, as dendrites receive signals from other neurons but do not release neurotransmitters for communication.

2. The ____ believed that consciousness developed in humans because it serves a useful purpose?

• A. Behaviorists
• B. Humanists
• C. Functionalists
• D. Structuralists

Correct answer: C

Rationale: Functionalists believed that consciousness evolved because it serves a useful purpose in helping humans adapt to their environment. Choice A, Behaviorists, focused on observable behaviors rather than consciousness. Choice B, Humanists, emphasized human potential and self-actualization. Choice D, Structuralists, studied the basic elements of consciousness rather than its function and purpose.

3. The process of ________ is used to increase the probability that a behavior will occur.

• A. operant conditioning
• B. reinforcement
• C. classical conditioning
• D. punishment

Correct answer: B

Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.

4. Deferred imitation of a caregiver's behavior shows that toddlers have the capacity to form?

• A. Short-term memory
• B. Working memory
• C. Core memories
• D. Long-term memory

Correct answer: D

Rationale: Deferred imitation refers to the ability of toddlers to observe and replicate behaviors after a period of time, indicating the formation of long-term memories. This process involves storing information for an extended period and recalling it at a later time. This capacity is not attributed to short-term memory (choice A), which is more temporary in nature and has limited storage capacity. Working memory (choice B) involves the temporary storage and manipulation of information for cognitive tasks, not necessarily the long-term retention of behaviors. Core memories (choice C) are typically associated with emotional or significant events rather than the replication of observed behaviors. Therefore, the correct answer is choice D, as deferred imitation demonstrates toddlers' capability to form long-term memories by replicating behaviors observed earlier.

5. During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?

• A. Embryo
• B. DNA
• C. Fetus
• D. Zygote

Correct answer: D

Rationale: The correct answer is D, Zygote. A zygote is formed when the 23 chromosomes from the ovum and sperm combine during conception. It is the initial cell formed and marks the beginning of a new organism. Choice A, Embryo, is incorrect as an embryo is formed later in the development process. Choice B, DNA, is incorrect as DNA is the genetic material within the chromosomes but is not the name of the new cell formed after fertilization. Choice C, Fetus, is incorrect as a fetus is the stage of prenatal development that occurs well after the zygote stage.
