Answer:
Omnivore flocks
will eat the most and if we are only taking Herbivores and carnivores as an example than herbivores flocks will eat the more because both seeds and fruits lay in the plant section.
What is the effect of the type of food available on the frequency of different types of bird beaks the lab procedure you just studied should help you address this question will it?
The food type changes in a given environment, then
the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time
. The independent variable of the lab is the type of food that is available to the birds.
Was your conclusion that the frequency of the beak type will change?
Answer: Hypothesis:
If the type of the food available changes
, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
How does nature select phenotypes such as bird beaks check all correct explanations?
How does nature “select” phenotypes, such as bird beaks? Check all correct explanations.
Traits that suit the environment enable an organism to reproduce in greater numbers
. … Traits other than beak type might affect natural selection.
Which flock will be able to eat the most Why?
Answer:
Omnivore flocks will
eat the most and if we are only taking Herbivores and carnivores as an example than herbivores flocks will eat the more because both seeds and fruits lay in the plant section.
Which flock will be able to eat the most the least why ??
Answer:
Omnivore flocks will eat the most
and if we are only taking Herbivores and carnivores as an example than herbivores flocks will eat the more because both seeds and fruits lay in the plant section. Explanation: The Flock are the collection of birds that fly and eat together in a group.
What is the final average beak depth?
The average beak depth of survivors was
9.84 mm
, compared to 9.31 mm in the general population before selection. Nevertheless some of the small birds did survive, and some of the birds with the very largest beaks did not.
What do you think a graph of population size would look like for Year 1 to Year 3?
What do you think a graph of population size would look like for Year 1 to Year 3?
Negative linear line
.
Why is the percentage of food eaten a good number to use?
Answer : The percentage of food gives an
idea about the food availability for the species of organisms
. If the food percentage is high the species is observed to be more successful; on the other hand if the percentage is low the species is found to shrink in numbers.
Why are the birds in this lab called Darwin’s finches?
The finches on the Galápagos Islands are called Darwin’s finches
because of the important role they played in the development of his theory of natural selection and evolution of species
.
What factors affect natural selection?
Four conditions are needed for natural selection to occur:
reproduction, heredity, variation in fitness or organisms
, variation in individual characters among members of the population. If they are met, natural selection automatically results.
What factors affect natural selection select three options?
Natural selection occurs if four conditions are met:
reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual
.
Which beak depth will be best for finding food in a drought?
1. Form hypothesis: What type of beak do you think will be best for finding food in a drought? (0.5 pt)
The middle to larger size beak type
will be best for finding food in a drought because they are able to eat big seeds and little seeds.
Which type of beak would have been best to allow the bird to survive the drought?
Because the drought reduced the number of seeds and finches with
bigger beaks
were able to eat the larger and harder seeds so more of them survived.
How do the bird populations respond to drought?
The change in food source for the birds during the drought—from small, soft seeds to large, hard seeds—may have selected for
birds with larger beak depths
. … Students may also point out that larger birds probably also have larger wings and larger beaks, and are thus more likely to survive.
Are the means in smaller samples different from the means in larger samples?
The means are different because each set of birds
was randomly selected from the larger group
, and since there is significant variation in beak depth in the population it is unlikely that the mean of any smaller sample will match the mean of the larger group.
