In an ecosystem with flys, frogs, birds and alligators.
the fly is eaten by the frog, the frog is eaten by the bird and the bird is eaten by the alligator, what will happen when the alligator population dies or when the frog population dies1) all prey species will increase in population
2) all predator species of the frog will decrease and the fly population will flourish.

What did Charles Darwin discover as a result of his experiments with breeding pigeons?
Desirable traits can be selected for and bred in offspring.
Humans can create new species through selective breeding.
Dogs and plants can be bred the in same way as pigeons.
The pigeons had distinctive traits that were passed on to offspring.
Desirable traits can be selected for and bred in offspring.
What did ms.c teach before science?
math
Which would least likely be a cause of natural selection?
adaptation
evolution
overpopulation
variation
Evolution
Define Natural Selection
a process that selects variations that help with survival and that spreads the variations to more offspring
Which statement would least likely be used to describe variation?
Variations are inherited differences between individuals of the same species.
Variations that decrease reproductive success are more likely to be passed on.
Variations may result in changes to an entire population after many generations.
Variations provide some individuals with an advantage.
Variations that decrease reproductive success are more likely to be passed on.
A population of white rabbits and brown rabbits both live in a temperate deciduous forest where the summers are mild and average about 50°F. The winters are often below freezing.
If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to happen to the population of each color of rabbit?
The brown rabbit population will slowly die out, and the white rabbit population will thrive and reproduce.
The brown rabbit population will thrive and reproduce, and the white rabbit population will slowly die out.
Both the white and brown rabbit populations will slowly die out.
Both the white and brown rabbit populations will thrive and reproduce.
The brown rabbit population will thrive and reproduce, and the white rabbit population will slowly die out.
What college did ms.c graduate from?

dark-colored hares living in a snowy area
mosquitoes that transmit disease to humans
giraffes having increasingly longer necks over time
giraffes having increasingly longer necks over time
DOUBLE JEOPARDY
what are the 3 types of diversities?
Define them
Genetic diversity: different genes within a population
species diversity: variety of organisms in an ecosystem
regional diversity: a variety of landscapes
Which was Charles Darwin’s contribution to the study of biology?
He was the first person to recognize that organisms change over time.
He believed that organisms adapted through the inheritance of acquired traits.
He explained how traits are passed from parents to offspring.
He proposed that natural selection is the primary mechanism of evolution.
He proposed that natural selection is the primary mechanism of evolution.
Variations within a species are an important part of Charles Darwin's theory of evolution. Which example can be explained by individual variation?
The food source in a lake is not enough to support the bass population, but it can support the trout.
A population of brown bears has doubled in the past 10 years.
Owls and foxes compete fiercely against each other for small rodents in their habitat.
Brightly colored cardinals are better able to survive and to reproduce than darker cardinals.
Brightly colored cardinals are better able to survive and to reproduce than darker cardinals.
What is Ms. C's wedding flower?
Sunflowers
Charles Darwin hypothesized that some individuals would be better equipped for survival than others, and that those that were less equipped would not survive. Darwin formulated this hypothesis based on the work of which scholar?
John Gould, who compared mainland and island finches
Thomas Malthus, who studied population growth
Sir Isaac Newton, who formulated the laws of motion
Gregor Mendel, who determined genetic inheritance of traits
Thomas Malthus, who studied population growth
define the difference between Macro and Micro Evolution
micro: evolution of the organism
macro: evolution of the population
According to the concept of “survival of the fittest," if a population of birds eats worms that they find deep under ground by using their beaks, which members of the bird population would be more fit?
birds that have flatter beaks
birds that have longer beaks
birds that have wider beaks
birds that have brighter beaks
Birds that have longer beaks
Populations of organisms that exhibit a high degree of variation have a greater chance for survival than populations of organisms that show little variation. This statement is
always true.
usually true.
rarely true.
never true.
Usually true
What is the name of Ms. C's fiance?
Bonus if you guess how many years we have been together
8 years
An example of natural selection is the red color of a male cardinal. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
increased variation in the shades of red because the selection pressure has been relieved
increased variation in the shades of red because the cardinals try different ways to impress the females
decreased variation in the shades of red because no form of the trait is advantageous
decreased variation in the shades of red because the only reason for variation was selection pressure
increased variation in the shades of red because the selection pressure has been relieved
