Examine the following scenario:

a population of small fish lives in a lake (lake a). the dark-colored fish are the ancestral phenotype and represent the usual coloration of the species. the bright-colored fish, however, arose over time.

there is a steady rise in the population of bright-colored fish. both populations thrive.

suppose that a short land barrier separates lake a from another small lake with a population of only the normal dark-colored fish (lake b). after torrential rains lasting for days, the lakes overflow and a few of the bright-colored fish from lake a are washed into lake b.

list the sequence of evolutionary mechanisms which have come into effect in each event.

a. genetic drift, mutation, natural selection
b. mutation, founder principle, bottleneck effect
c. mutation, natural selection, migration (gene flow)

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i. e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
