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. Which term refers to events that typically happen to everyone at certain times of life?

A. Normative age-graded influence
B. Social clock
C. Sensitive period
D. Normative history-graded influences

Correct answer: A

Rationale: The correct answer is A: Normative age-graded influence. Normative age-graded influences are events that typically happen to everyone at certain life stages, such as marriage, parenthood, puberty, and menopause. Choice B, 'Social clock,' refers to the culturally preferred timing of social events. Choice C, 'Sensitive period,' represents a time when a particular development occurs most easily. Choice D, 'Normative history-graded influences,' are common to people of a particular generation due to historical circumstances.

3. Michael, age 16, has recently gained a considerable amount of weight but has not grown any taller. His father experienced a similar pattern of growth when he was a teenager. Theorists who suggest that Michael’s growth pattern was inherited from his father emphasize the ________ side of the nature-nurture debate?

A. Nature
B. Nurture
C. Environmental
D. Experiential

Correct answer: A

Rationale: The correct answer is 'A: Nature.' In this scenario, the emphasis is on the genetic inheritance of the growth pattern from father to son, highlighting the role of nature in determining physical characteristics. Choice B, 'Nurture,' focuses on environmental influences, which are not the primary factor in this case. Choice C, 'Environmental,' is similar to 'Nurture' and does not address the genetic aspect mentioned. Choice D, 'Experiential,' pertains more to the learning and experiential aspects rather than genetic inheritance, making it an incorrect choice.

4. How do defense mechanisms contribute to psychopathology?

A. They do not contribute to psychopathology as they are healthy coping mechanisms.
B. They contribute to psychopathology by allowing individuals to avoid confronting painful realities.
C. Defense mechanisms have no connection to psychopathology.
D. Defense mechanisms are unconscious strategies that can lead to the development of psychopathology.

Correct answer: B

Rationale: The correct answer is B. Defense mechanisms contribute to psychopathology by allowing individuals to avoid confronting painful realities. This avoidance can prevent individuals from dealing with underlying issues, leading to the development or exacerbation of psychopathological conditions. Choice A is incorrect because while defense mechanisms may serve as coping mechanisms, they can also contribute to psychopathology when used excessively or inappropriately. Choice C is incorrect as defense mechanisms are indeed connected to psychopathology. Choice D is incorrect because defense mechanisms, when maladaptive, can contribute to psychopathology rather than being considered healthy coping strategies.

5. 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.
