Answer:
The embryonic stage.
Explanation:
The prenatal development goes through three different stages:
- The germinal stage: Begins at conception and it takes place during the next 2 weeks.
- The embryonic stage: It takes place from week two to eight weeks after conception. During this stage, the embryo begins to differentiate itself into three layers that will become different systems of the body. By week eight, the basic structures of the brain and central nervous system have been established and the organs start to appear.
- The fetus stage: It takes place from week 9 until birth. The systems formed in the previous stage continue to form until they are ready for birth.
Therefore, the period of prenatal development that occurs two to eight weeks after conception. During this period, the rate of cell differentiation intensifies, support systems for the cells form, and organs appear is called the embryonic stage.
I believe the answer is: Reference group
Reference group refers to the group that become subjects of comparison to another group of individual.
Most people use this reference group to measure our own worth (for example, if you want to know whether you a bad or good guitar player, the reference group that you would most likely use would be famous band member) , and this might influence the formation of our identity in the future.
Answer:
Ecological Validity
Explanation:
According to my research on different research methodology, I can say that based on the information provided within the question this study is lacking in Ecological Validity. This refers to to the extent to which the findings of a research study are able to be generalized to real-life settings. This is because like mentioned in the question this study is addressing a situation that does not happen in everyday life therefore it cannot be generalized to a real-life settings.
