Which of the following statements is incorrect? The slow step in a mechanism generally involves a three-body collision. After the addition of a catalyst, the collision rate between molecules is still the same. Most collisions between reactant molecules do not lead to a product Chemical reactions involve collisions between the participating molecules. A three-body collision is less likely than a two-body collision.

QUESTION 2 Which of the following is TRUE regarding the possible interbreeding between the human and Neanderthal species? a. A limited amount of variation has been passed from Homo neanderthalensis to Eurasian populations of Homo sapiens as a result of interbreeding that probably took place in the Near East at some point within the past 100,000 years. b. There is no evidence of hybridization between Neanderthals and modern humans. Both bone mtDNA and genomics studies ruled out such interbreeding. C....

The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...
