Question
1-How is extinction related to speciation? too many species increase the chance of extinction when a species is fit for an unique environment, if that environment changes, it can go extinct a successful species will drive all others to extinction 2-What are the five agents of microevolution? gamete production; mating; fertilization; caring for offspring; formation of herds photosynthesis; respiration; mitosis; meiosis; fertilization mutation; gene flow; nonrandom mating; genetic drift; natural selection 3-After a drought, what happened to the average beak size of medium ground finches? they decreased in size they remained the same they increased in size 4-What is Circadian rhythm? the cell cycle animal behavior that follows the daily cycle the life cycle of a species 5-Can we see evolution in progress? What is a good example? no; evolution takes too long to observe yes; the presence of human genetic disorders yes; an increase in black moths following accumulation of soot in London 6-What is altruism? behavior that benefits the individual despite potential risk to the population behavior that benefits the population despite potential risk to the individual behavior that equally benefits the individual and the population 1-How is extinction related to speciation? too many species increase the chance of extinction when a species is fit for an unique environment, if that environment changes, it can go extinct a successful species will drive all others to extinction 2-What are the five agents of microevolution? gamete production; mating; fertilization; caring for offspring; formation of herds photosynthesis; respiration; mitosis; meiosis; fertilization mutation; gene flow; nonrandom mating; genetic drift; natural selection 3-After a drought, what happened to the average beak size of medium ground finches? they decreased in size they remained the same they increased in size 4-What is Circadian rhythm? the cell cycle animal behavior that follows the daily cycle the life cycle of a species 5-Can we see evolution in progress?

1.ANS: C (a successful species will drive all others to extinction).
Speciation: It is a process of a evolution, in which changes takes placed in gene flow of a populations from their ancestral species.
Extinction: It is a process in which the species losses permanently.
The most common phenomenon between speciation and extinction is both will change species. Only successful species will drive and remaining all other will die.
2.ANS: C (mutation; gene flow; nonrandom mating; genetic drift; natural selection).
3.ANS: C (they increased in size).
Changes in food supply created selection pressure that caused finch population to evolve. So after a drought the average beak size of medium ground finches is increased in size.
4.ANS: B (animal behavior that follows the daily cycle).
Circadian rhythm is the regular recurrence of action of certain phenomena in cycles of approximately 24 hours.
5.ANS: C (yes; an increase in black moths following accumulation of soot in London).
In Industrial revolution 19th century at England, the color of moth population is shifted from light to dark.
6.ANS: B (behavior that benefits the population despite potential risk to the individual).
Altruistic behavior reduces individual fitness but increase fitness of recipient.
