The reticular activating system's main function is regulating arousal and sleep−wake transitions
Twin Studies-genetic-the answer is true, according to quizlet -> The rationale for twin studies is that both identical and fraternal twins normally develop under similar environmental conditions. However, identical twins share more genetic kinship than fraternal twins. So if pairs of identical twins are more similar in intelligence than fraternal twins, it's presumably because of their greater genetic similarity.
And these studies do show that on average, identical twins are more similar than fraternal twins.
Is there any optional answers?
The correct answer is B. The science of inherited traits
Explanation:
Genetics refers to the field in biology that focuses on studying genes which are the basic units of heredity and therefore the ones that determine inherited traits. Indeed genetic study the way traits are passed through reproduction and also the way genes change over time or express which is closely connected to evolution. Additionally, genetics have been widely studied beginning by the works of Mendel during the 19th century and nowadays the knowledge about genes including the behavior, function, and structure of them is broad. According to this, genetics is defined as the science of inherited traits.
