How many different species of birds belong to the animal kingdom
Why the honeycreeper when extinct
the Adaptive radiation observed by Darwin
how scientists have altered the genetic code of birds
Which of the following choices might be a threat to biodiversity?
A new species of snake is introduced to an ecosystem
Scientists work to restore a habitat and save native species
All of the choices are correct
A study program monitors the levels of pollutants in local rivers
Over a thousand year period, a new species of bird slowly evolves that is more aerodynamic and needs less water to adapt to an arid, windy environment. This is an example of:
Adaptive radiation
punctuated equilibrium
coevolution
gradualism
The Endangered Species Act
was passed in 2010
made it illegal to transport endangered species and their products
prevented zoos from breeding endangered anumals
is enforced globally
Which of the following statements about mammals and reproduction is correct
mammals produce offspring through asexual reproduction and regular cell division
mammal offspring have a greater chance of survival than fish offspring
Most mammals lay eggs
Mammals produce more offspring than fish and amphibians
One advantage that sexual reproduction has over asexual reproduction is that
produces greater genetic diversity
prevents the species from becoming extinct
protects a species from natural disasters
all of the above
The organism in this image
frightens predators with the owl eyes on its wings
has no adaptations to survive
is from the plant kingdom
is a predator
A person who does not believe in Evolution might argue
homologous structures exist across all species
the early stages of embryo development are similar in many species
the fossil record is incomplete and has many gaps
all of the above
the organism here uses its coloration to
attract a mate
warm predators that it is poisonous
all of the choices are correct
hide from predators
The Endangered Species Act
protects animals, but not plants
only applies to marine life
requires federal agencies to ensure that their actions are not likely to jeopardize the existence of any endangered species
is overseen by a global task force
The loss of a single species of plants in an ecosystem
will not cause any significant changes
is always the result of inbreeding
may start a chain of events that negatively affects every organism in the ecosystem
none of these are correct
Which of the following choices is an example of an inherited trait
eye color
all of these
hair color
height
How does meiosis differ from regular cell division
meiosis uses less energy
In meiosis DNA copies itself
meiosis only happens in spinal cells
Meiosis produces carbon dioxide while regular cell division produces oxygen
Bats and birds developing structures for flight desperately is an example of
genetic diversity
artificial selection
artificial evolution
convergent evolution
Angiosperms
do not have vascular tissue
are found in the ocean
produce flowers and seeds
are evergreens
