Fragen in diesem Quiz (10)
1THE BIG PICTURE- Comparative anatomy provides evidence
- AThat mammals are dissimilar
- BThat mammals use their limbs for different purposes
- CThat mammals existed in the past
- DThat mammals all share a common mammalian ancestor
2An explanation for the different species of honeycreepers on the Hawaiian islands is
- AThe habitats were different on the different islands and selected different traits
- BEach bird was created separately to survive in different environmental conditions
- CDifferent traits that were needed for survival appeared in the birds so that the birds did not go extinct
- DThat all of the birds of Hawaii share a common ancestor
3An explanation for the difference in a.a between lamprey Hb and human Hb is:
- ALampreys live in the water and don´t need as much Hb
- BLamprey Hb and human Hb perform different functions
- CThe common ancestor for humans and lampreys is very far in the past
- DLampreys and humans are not related
4EVOLUTION IN ACTION- Why is it relevant that the definition of “population” is individuals of the same species in the same area?
- ABecause biology is the study of species
- BBecause data cannot reliably be collected in more than one place
- CBecause only individuals of the same species in the same place can reproduce
- DBecause individuals of a population may impact each other´s survival
5Why do some flies live only 12 hours and others live 30 hours without food?
- ABecause some flies ate more food before the food was removed
- BBecause there is variation in the population for starvation resistance
- CBecause some flies needed to live longer without food
- DBecause some flies conserved more energy by flying less
6Which of the following is the hypothesis for your fruit fly experiment?
- AHow long can fruit flies survive before starvation?
- BEvolution is something we can observe
- CFruit flies will become starvation resistant when they need to survive
- DFruit flies can be bred to live longer before starvation
7Why select the 20 % most starvation resistant flies
- ABecause you are selecting for a trait than impacts survival and reproduction
- BBecause you are selecting flies that can reproduce
- CBecause you are selecting flies that have acquired starvation resistance
- DBecause you need to have some flies reproduce
8What happens when a fruit fly fails to reproduce?
- AIts genes must be carried by another individual in the population
- BOnly some of its genes will pass into the next generation
- CNone of its genes will pass into the next generation
- DIts genes will skip a generation
9Why are the Generation 60 flies fatter than the Generation 1 flies?
- ABecause they needed to evolve the ability to resist starvation
- BBecause some had genes that allowed them to survive longer without food
- CBecause the flies ate more food in Generation 60 so that they could survive longer without food
- DBecause some had traits that they acquired that allowed them to survive without food
10What does reproductive success for the bacteria mean?
- AThat some individuals were able to pass their genes into the next generation
- BThat some individuals were able to resist the antibacterial soap
- CThat all individuals reproduced successfully
- DThat all were able to resist the antibacterial soap
