Human Growth and Development Exam 1

1. During pregnancy, the placenta __________.

Correct answer: D

Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.

2. Max, age 65, learned to play the piano at a local senior center. Max demonstrates that __________.

Correct answer: C

Rationale: Max, age 65, learning to play the piano at a local senior center demonstrates that development is plastic at all ages. This means that individuals have the potential to learn and grow regardless of their age, showing that it is never too late to acquire new skills and experiences. Choice A is incorrect because it presents a negative view of aging, which is not supported by Max's actions. Choice B is incorrect as it implies that learning is restricted to certain age periods, which is contradicted by Max's experience. Choice D is incorrect because Max's learning of the piano at 65 suggests that musical talent can be developed at any age, not necessarily peaking in late adulthood.

3. Although great diversity characterizes the interests and concerns of investigators who study development, they share a single goal: to identify __________.

Correct answer: D

Rationale: The correct answer is D because investigators who study development aim to identify the factors that influence consistencies and transformations in people from conception to death. This goal encompasses various domains such as physical, cognitive, emotional, and social development, highlighting the comprehensive nature of developmental research. Choices A, B, and C are incorrect as they do not align with the overarching goal of developmental researchers, which is to understand the factors influencing individuals throughout their lifespan, rather than focusing solely on genetic factors, environmental factors related to disease, or abnormal development in specific age groups.

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

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.

5. Mothers who __________ have fewer birth complications and shorter labors.

Correct answer: C

Rationale: According to research, mothers who are supported by a trained companion during childbirth have fewer birth complications and shorter labors. This support can reduce stress and anxiety levels, provide comfort and encouragement, and help the mother feel more in control during labor and delivery. Overall, having a trained companion present can contribute to a more positive childbirth experience for the mother. Choices A, B, and D are incorrect because they do not align with the research findings that specifically highlight the benefits of having a trained companion during childbirth.
