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
Image:

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:
Image:

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?
Image:
8ec0d96f-de89-4667-8064-5f63d62e0117 (image/jpg)
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?
Image:
2f19050f-64cd-45d2-bb68-796fa4ec31b3.gif (image/gif)
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?
Image:
7ab99cc0-b7fd-4ea3-ad17-c5ec33065e5f.gif (image/gif)
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
Image:
9e4e7428-9f9c-4146-a6db-500310c625b5.gif (image/gif)
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?
Image:
55d99382-82b3-4583-915d-d132a23047e5.gif (image/gif)
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?
Image:
635fca27-59cf-4983-9434-10e1b352fc42 (image/jpg)
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?
Image:
a752ba8a-fb7b-4722-8aff-9cc3f4793551 (image/png)
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
