Pregunta 1
Pregunta
THE BIG PICTURE- Comparative anatomy provides evidence
Respuesta
-
That mammals are dissimilar
-
That mammals use their limbs for different purposes
-
That mammals existed in the past
-
That mammals all share a common mammalian ancestor
Pregunta 2
Pregunta
An explanation for the different species of honeycreepers on the Hawaiian islands is
Respuesta
-
The habitats were different on the different islands and selected different traits
-
Each bird was created separately to survive in different environmental conditions
-
Different traits that were needed for survival appeared in the birds so that the birds did not go extinct
-
That all of the birds of Hawaii share a common ancestor
Pregunta 3
Pregunta
An explanation for the difference in a.a between lamprey Hb and human Hb is:
Respuesta
-
Lampreys live in the water and don´t need as much Hb
-
Lamprey Hb and human Hb perform different functions
-
The common ancestor for humans and lampreys is very far in the past
-
Lampreys and humans are not related
Pregunta 4
Pregunta
EVOLUTION IN ACTION- Why is it relevant that the definition of “population” is individuals of the same species in the same area?
Respuesta
-
Because biology is the study of species
-
Because data cannot reliably be collected in more than one place
-
Because only individuals of the same species in the same place can reproduce
-
Because individuals of a population may impact each other´s survival
Pregunta 5
Pregunta
Why do some flies live only 12 hours and others live 30 hours without food?
Respuesta
-
Because some flies ate more food before the food was removed
-
Because there is variation in the population for starvation resistance
-
Because some flies needed to live longer without food
-
Because some flies conserved more energy by flying less
Pregunta 6
Pregunta
Which of the following is the hypothesis for your fruit fly experiment?
Respuesta
-
How long can fruit flies survive before starvation?
-
Evolution is something we can observe
-
Fruit flies will become starvation resistant when they need to survive
-
Fruit flies can be bred to live longer before starvation
Pregunta 7
Pregunta
Why select the 20 % most starvation resistant flies
Respuesta
-
Because you are selecting for a trait than impacts survival and reproduction
-
Because you are selecting flies that can reproduce
-
Because you are selecting flies that have acquired starvation resistance
-
Because you need to have some flies reproduce
Pregunta 8
Pregunta
What happens when a fruit fly fails to reproduce?
Respuesta
-
Its genes must be carried by another individual in the population
-
Only some of its genes will pass into the next generation
-
None of its genes will pass into the next generation
-
Its genes will skip a generation
Pregunta 9
Pregunta
Why are the Generation 60 flies fatter than the Generation 1 flies?
Respuesta
-
Because they needed to evolve the ability to resist starvation
-
Because some had genes that allowed them to survive longer without food
-
Because the flies ate more food in Generation 60 so that they could survive longer without food
-
Because some had traits that they acquired that allowed them to survive without food
Pregunta 10
Pregunta
What does reproductive success for the bacteria mean?
Respuesta
-
That some individuals were able to pass their genes into the next generation
-
That some individuals were able to resist the antibacterial soap
-
That all individuals reproduced successfully
-
That all were able to resist the antibacterial soap
