1. Which statement about a blastocyst is true?

• A. It consists of a single cell.
• B. It is a structure that feeds the developing organism.
• C. Between the seventh and ninth days, it burrows deep into the uterine lining.
• D. It is a membrane that helps to keep the temperature of the prenatal world constant.

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.

2. Alfred Binet and Theodore Simon __________.

• A. wrote the first book of its time on aging
• B. were among the first to make child development knowledge meaningful to parents
• C. regarded development as a maturational process
• D. constructed the first successful intelligence test Answer: D Page Ref: 14 Skill Level: Remember Topic: Scientific Beginnings Difficulty Level: Moderate

Correct answer: D

Rationale: Alfred Binet and Theodore Simon constructed the first successful intelligence test, known as the Binet-Simon scale, in an effort to measure a child's intelligence level. This test was groundbreaking at the time and laid the foundation for the development of future intelligence tests.

3. The term teratogen refers to __________.

• A. any environmental agent that causes damage during the prenatal period
• B. a limited time span during which a part of the body is biologically prepared to develop rapidly
• C. a rapid period of prenatal neurological development
• D. a synthetic hormone used to prevent miscarriage

Correct answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.

4. The lifespan perspective on human development assumes that development is __________.

• A. static and stable
• B. multidimensional and multidirectional
• C. continuous, rather than discontinuous
• D. largely the result of heredity

Correct answer: B

Rationale: The lifespan perspective on human development assumes that development is multidimensional and multidirectional. This means that development occurs in various domains (such as physical, cognitive, and psychosocial) and can involve gains and losses as individuals age. This perspective recognizes that human development is complex and dynamic, involving various factors and pathways over the course of a person's life. Choices A, C, and D are incorrect because human development is not static and stable (A), can involve both continuous and discontinuous changes (C), and is influenced by a combination of heredity and environment rather than solely by heredity (D).

5. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?

• A. The death of a spouse causes a decline in the surviving partner's physical health.
• B. The death of a spouse is related to a decline in the surviving partner's physical health.
• C. A decline in a surviving partner's physical health can cause the death of a spouse.
• D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.

Correct answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.
