1. Recent evidence suggests that paternal alcohol use around the time of conception __________.

• A. can alter gene expression
• B. can cause fetal alcohol syndrome
• C. is linked to blood vessel abnormalities
• D. has no negative effect on the developing organism

Correct answer: A

Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.

2. Ethnographies reveal that immigrant parents view __________ as the surest way to improve life chances.

• A. learning English
• B. education
• C. close ties to an ethnic community
• D. moving into an urban area

Correct answer: B

Rationale: Ethnographies reveal that immigrant parents prioritize education as the surest way to improve life chances for their children. While learning English is important for integration, education is considered the key for better opportunities and success in the long term. Close ties to an ethnic community can provide support but may not directly lead to improved life chances. Moving into an urban area is not highlighted in the context of immigrant parents' views on improving life chances through their children's development.

3. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.

• A. long-lived predatory fish; mercury
• B. freshwater fish; lead
• C. long-lived predatory fish; polychlorinated biphenyls
• D. freshwater fish; radiation

Correct answer: A

Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.

4. An ovum bursts from one of a woman's two __________ and is drawn into one of two __________.

• A. ovaries; testes
• B. fallopian tubes; ovaries
• C. corpus luteum; fallopian tubes
• D. ovaries; fallopian tubes Answer: D Page Ref: 76 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Easy

Correct answer: D

Rationale: An ovum bursts from one of a woman's two ovaries and is drawn into one of two fallopian tubes. This is a correct description of the process of ovulation and fertilization in human reproductive anatomy. The ovaries are responsible for producing and releasing eggs, while the fallopian tubes provide a pathway for the egg to travel to the uterus for potential fertilization.

5. It is difficult to isolate the precise damage caused by illegal drugs during pregnancy because __________.

• A. most drug-using mothers refuse to participate in teratology research
• B. the majority of babies born to drug-using mothers do not survive for more than a few days
• C. most drug-using mothers quit using illegal drugs during the first trimester of pregnancy
• D. drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses

Correct answer: D

Rationale: The difficulty in isolating the precise damage caused by illegal drugs during pregnancy is due to the fact that drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses. This makes it challenging to identify the specific impact of each individual factor on prenatal development. Choices A, B, and C are incorrect because they do not address the complexity of the situation involving drug users during pregnancy. Most drug-using mothers refusing to participate in teratology research, the majority of babies not surviving, or drug-using mothers quitting during the first trimester do not directly explain the difficulty in isolating the precise damage caused by illegal drugs during pregnancy.
