what do genes consist of

ATI RN

Psychology 101 Exam 3 Test

1. What are genes made of?

A. Trisomes
B. Chromosomes
C. DNA
D. Proteins

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

2. The ______________ perspective in psychology takes into account biological, sociological, and psychological factors associated with a person's behaviors.

A. Behavioral
B. Cognitive-behavioral
C. Psychodynamic
D. Biopsychosocial

Correct answer: D

Rationale: The biopsychosocial perspective is the correct answer as it considers biological, sociological, and psychological factors associated with a person's behaviors. This perspective emphasizes the interconnection between these factors in understanding human behavior. Choice A, Behavioral perspective, focuses primarily on observable behaviors and how they are influenced by the environment. Choice B, Cognitive-behavioral perspective, combines elements of cognitive and behavioral theories to understand behavior but does not encompass sociological factors. Choice C, Psychodynamic perspective, emphasizes unconscious processes and early childhood experiences as determinants of behavior, neglecting the sociological aspect.

3. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

A. Amnion
B. Placenta
C. Umbilical cord
D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.

4. Scientific research has demonstrated the __________ parenting style is most likely to lead to healthy psychological development in children.

A. Authoritarian
B. Permissive
C. Authoritative
D. Neglectful

Correct answer: C

Rationale: Scientific research has demonstrated that the authoritative parenting style is most likely to lead to healthy psychological development in children. Authoritative parents are responsive to their children's emotional needs, set clear boundaries, and encourage independence. This balance fosters a positive environment for children to thrive emotionally and psychologically. Authoritarian parenting (choice A) focuses on strict rules without much warmth, which can lead to obedience but may hinder emotional development. Permissive parenting (choice B) lacks structure and rules, potentially resulting in children feeling insecure. Neglectful parenting (choice D) is characterized by a lack of responsiveness and involvement, leading to various negative outcomes for the child's development.

5. Michael, age 16, has recently gained a considerable amount of weight but has not grown any taller. His father experienced a similar pattern of growth when he was a teenager. Theorists who suggest that Michael’s growth pattern was inherited from his father emphasize the ________ side of the nature-nurture debate?

A. Nature
B. Nurture
C. Environmental
D. Experiential

Correct answer: A

Rationale: The correct answer is 'A: Nature.' In this scenario, the emphasis is on the genetic inheritance of the growth pattern from father to son, highlighting the role of nature in determining physical characteristics. Choice B, 'Nurture,' focuses on environmental influences, which are not the primary factor in this case. Choice C, 'Environmental,' is similar to 'Nurture' and does not address the genetic aspect mentioned. Choice D, 'Experiential,' pertains more to the learning and experiential aspects rather than genetic inheritance, making it an incorrect choice.
