When Charles Darwin visited the Galapagos Islands in the 1800s, he observed many types of organisms that were simliar but lived on different islands. Four of the species of birds found are shown below. Each one lives on a different island. While these species are very similar, the Hood mockingbird has a longer beak than the other three species. Which of the following could explain this difference?
The Hood mockingbird needs a longer beak for defense against predators.
The Hood mockingbird originated from a different type of bird than the other species.
The Hood mockingbird's longer beak is an adaptation to the food available in the birds habitat.
The Hood mockingbird's beak stretched and grew to reach its food.
What would likely occur after a farm is hit by a tornado?
The land would slowly grow back, demonstrating primary succession.
The land would rapidly return, demonstrating seed dispersal.
The land would slowly grow back, demonstrating secondary succession.
The land would likely be susceptible to an earthquake since it is now weaker than before.
Which statement is true of both natural selection and artificial selection?
Natural selection is controlled by nature and artificial selection is controlled by humans
Natural selection happens quickly while artificial selection takes time
Natural selection is known as selective breeding and artificial selection is known as survival of the fittest
Natural selection breeds offspring with desired traits while artificial selection involves species being better able to survive in their environment
Which of the following can pollute our groundwater by being absorbed by the soil?
Fertilizer
Animal waste
Insecticides
All of the above can contaminate our groundwater.
Selective breeding has been used in farming practices for years and a large majority of the foods you eat are products of selective breeding, or artificial selection.
True
False
The image below shows the parts of a watershed. Which answer below best explains human impact on groundwater?
. The activities shown will replace the groundwater quickly.
The activities get into the soil and eventually reach the groundwater or aquifers.
The activities only pollute the land, not the water.
The activities don't typically cause any runoff.
In the phrase "survival of the fittest", what does the term "fittest" refer to?
The strongest
The best adapted to its environment
The smartest
. The fastest
Galveston Bay is an estuary in Southeast Texas. An estuary is an area that contains a mixture of fresh water and salt water. The amount of salt in the estuary changes based on the tides. Sometimes the water is mostly freshwater and sometimes is it mixed with saltwater. Various plants live in this environment and provide a habitat for other living things.
For a plant to successfully live in an estuary, it must have an adaptation that allows it to
produce a large amount of food
absorb large amounts of water
. store excess carbon dioxide
filter and remove extra salt water before it absorbs into the roots
Which of the following scenarios would be considered weathering?
Soil particles falling into a stream
Rock fragments breaking off from a mountain
Sand being dropped off on the shore
A flowing river moving soil particles
Which of the following is an example of a favorible mutation, or one that is helpful to the organism?
A mutation that turns a squirrels fur hot pink.
A mutation that makes a squirrel run faster.
mutation that makes the squirrel have different color eyes
mutation that gives the squirrel an extra tail.
Which of the following is an example of primary succession?
A forest recovering from a wildfire
. A garden regrowing
A new island emerging from the sea
Corn crops recuperating after a flood
Some dairy farmers want to increase the amount of milk produced by their cows. How can the farmers use selective breeding to increase milk production?
By increasing the age of the cows that are bred
. By choosing cows that are high milk producers to breed new cows
By limiting the number of offspring or babies each cow has
choosing cows that can produce milk after eating the most food
Peppered Moths are normally white with black speckles across the wings, giving it its name. This patterning makes it well camouflaged against lichen-covered tree trunks when it rests on them during the day. However, in the nineteenth century it was noticed that in towns and cities it was actually the black form of the moth that was more common than the pale peppered form. Industrialisation and domestic coal fires had caused sooty air pollution which had killed off lichens and blackened urban tree trunks and walls. This situationa above is an example of which type of selection?
Natural Selection
Artificial Selection
