Glycolysis, Krebs cycles and electron transport chain are the three steps of cellular respiration, for converting glucose into energy.
Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
B) glucose (get it glycolysis?) it starts with glucose and ends with 2 pyruvic acids
The cell transport process that is opposite of the three pictured is call C. exocytosis.
