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. Genes ________

• A. determine how a person will behave.
• B. cause people to develop mental disorders.
• C. determine what characteristics a person will have.
• D. determine the range of characteristics a person has.

Correct answer: D

Rationale: Genes determine the range of characteristics a person has. Choice A is incorrect because genes do not solely determine behavior, as behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because while genes can contribute to the risk of developing mental disorders, they do not directly cause them. Choice C is incorrect as genes contribute to but do not solely determine all characteristics a person will have.

3. In a breech presentation, how is the infant positioned for delivery?

• A. Is too large to be delivered vaginally.
• B. Is delivered feet or bottom first.
• C. Is delivered head first.
• D. Appears face down.

Correct answer: B

Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.

4. In order for one to be diagnosed with panic disorder, the panic attacks must?

• A. Suddenly; unexpectedly
• B. Suddenly; gradually
• C. Gradually; unexpectedly
• D. Unexpectedly; suddenly

Correct answer: A

Rationale: The correct answer is A: 'Suddenly; unexpectedly.' Panic disorder is diagnosed when panic attacks occur unexpectedly, not gradually. Panic attacks are characterized by their sudden onset and are unpredictable. Choice B is incorrect because panic attacks do not manifest gradually. Choice C is incorrect because panic attacks are not expected or predicted. Choice D is incorrect as well because the unexpected nature of panic attacks is a key criterion for diagnosing panic disorder.

5. What does the diathesis-stress model entail?

• A. The diathesis-stress model suggests that stress alone is sufficient to cause a mental disorder.
• B. The diathesis-stress model involves a combination of genetic vulnerability and environmental stressors.
• C. The diathesis-stress model suggests that genetic factors alone cause mental disorders.
• D. The diathesis-stress model suggests that stressors in the environment do not affect the onset of mental disorders.

Correct answer: B

Rationale: The diathesis-stress model proposes that mental disorders develop from a combination of genetic vulnerability (the diathesis) and environmental stressors. Choice A is incorrect because it states that stress alone can cause mental disorders, which is not in line with the model. Choice C is incorrect as it simplifies the model to genetic factors alone causing mental disorders. Choice D is incorrect as it suggests that environmental stressors do not play a role in the onset of mental disorders, which contradicts the essence of the diathesis-stress model.
