1. 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.

2. Alicia, 5 years old, knows that she will take a bath at 6:05, change clothes at 6:15, eat breakfast at 6:20, commute to school at 6:40, and join the assembly at 7:00. A child's awareness of his or her scripts or daily routine is classified under which type of memory?

• A. Semantic memory
• B. Nondeclarative memory
• C. Generic memory
• D. Autobiographical memory

Correct answer: D

Rationale: The correct answer is D, Autobiographical memory. Autobiographical memory refers to the memory of a person's life events, such as daily routines and personal experiences. In this scenario, Alicia's awareness of her daily routine falls under autobiographical memory as she remembers specific events related to her own life. Choices A, B, and C are incorrect. Semantic memory is related to general knowledge about the world, nondeclarative memory involves memories that are not consciously recalled, and generic memory is not a recognized memory classification.

3. In order to develop chicken pox, one must be exposed to the virus that causes chicken pox. Note, however, that not everyone who is exposed to the virus is affected. In other words, the virus is a ________

• A. risk factor.
• B. necessary cause.
• C. sufficient cause.
• D. contributory cause.

Correct answer: B

Rationale: The correct answer is B: 'necessary cause.' A necessary cause must be present for a disorder to occur. In the context of developing chicken pox, being exposed to the virus is a necessary condition for contracting the disease. Choices A, C, and D are incorrect. A 'risk factor' increases the probability of developing a disease but is not essential for its occurrence. A 'sufficient cause' can produce the outcome on its own, which is not the case with exposure to the chicken pox virus. A 'contributory cause' adds to other causes to produce an effect, but in this scenario, exposure to the virus is crucial by itself.

4. Children raised in orphanages tend to have ________.

• A. more cortical gray matter than those raised by their parents.
• B. less cortical gray matter than those raised by their parents.
• C. more friendships than those raised by their parents.
• D. fewer friendships than those raised by their parents.

Correct answer: B

Rationale: The correct answer is B: 'less cortical gray matter than those raised by their parents.' Studies have shown that children raised in orphanages tend to have less cortical gray matter compared to those raised by their parents. This is due to the lack of individualized care, attention, and stimulation that can negatively impact brain development. Choices A, C, and D are incorrect because there is no direct correlation between cortical gray matter and the number of friendships when comparing children raised in orphanages and those raised by their parents.

5. Freud's psychosexual stage that occurs between the ages of 3 and 5 and includes the Oedipal period is the _________ stage.

• A. Oral
• B. Anal
• C. Phallic
• D. Genital

Correct answer: C

Rationale: The correct answer is C: Phallic. Freud's psychosexual stage that occurs between ages 3 and 5 and includes the Oedipal period is the phallic stage. This stage is characterized by the Oedipus complex for boys and the Electra complex for girls. Choices A, B, and D are incorrect because the oral stage typically occurs during the first year of life, the anal stage occurs around ages 2 to 3, and the genital stage is the final stage in Freud's theory of psychosexual development.
