Question 1 of 5

In his research study, Dr. Johnson gives participants false feedback about their performance. Consequently, Dr. Johnson should use __________ after the research session is over.

Debriefing involves explaining the true nature of the study, including any deception that occurred, to the participants in order to protect their well-being and address any lingering concerns or misconceptions they may have. It is an important ethical practice in research to ensure participants are fully informed about the study they were involved in.

Question 3 of 5

The yolk sac __________.

Correct Answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

Question 4 of 5

The other options (B. type of books parents read, C. child's vocabulary score, and D. difficulty of vocabulary words) are not the independent variable in this study as they are either irrelevant or are the outcome being measured.
