1. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.

A. malnutrition
B. physical abnormality
C. low birth weight
D. sudden infant death syndrome

Correct answer: C

Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.

2. 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.

3. According to __________ theory, children learn primarily through modeling.

A. reinforcement
B. operant conditioning
C. social learning
D. classical conditioning

Correct answer: C

Rationale: According to social learning theory, children primarily learn through modeling, observation, and imitation of others. This theory emphasizes the importance of cognitive processes in learning, as opposed to only focusing on direct reinforcement or punishment. Social learning theory was developed by psychologist Albert Bandura and is a key theory in the field of child development. Choice A, reinforcement, is incorrect as it refers to the process of strengthening a behavior through rewards or punishments. Choice B, operant conditioning, is also incorrect as it is a learning process that involves reinforcement and punishment to shape behavior. Choice D, classical conditioning, is not the correct answer as it involves learning through association between stimuli.

4. 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.

5. __________ may heighten the effects of a high-fat diet.

A. Sex hormones
B. Over-the-counter medications
C. Free radicals
D. Low body weight

Correct answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.
