Sexual reproduction carries with the potential for genetic mutation. Some mutations are destructive as they make an organism less capable of surviving, while other mutations are beneficial, and improve the individual's chance for survival. If an animal has a genetic mutation that allows it to defend itself extremely well, which of the following is most likely to occur?
The characteristic would skip the immediate offspring and appear in a future generation.
The characteristic would disappear from the species in a few generations.
The characteristic would be passed on to every member of the next generation.
The characteristic would be represented in more individuals in successive generation.
Fossils that show the intermediate state of an organisms between an ancestor and later descendant are called transitional forms. Transitional forms would most likely be found:
living as their own species.
in layers of sediment above ancestral forms.
living as modern-day organisms.
in layers of sediment below ancestral forms.
The diagram shows that many generations of genetic changes led to the modern-day giraffe. Based on the diagram, its is plausible the giraffe formed.
a narrower head to reach deep into trees and eat food that is hard to reach.
longer legs to attack predators that approach.
a longer neck to reach food in higher areas when food is scarce.
more spots to attract mates to produce offspring.

F. Organisms that are naturally selected are at the higher risk of extinction.
D. Changes within a population happen immediately when the environment changes.

A. There is a struggle for survival, which results in the production of more offspring than can survive.
B. Differences in traits are determined by an organism's immediate needs.
C. Organisms that are better adapted to their environment will have a greater chance of survival reproduction.
A. There is a struggle for survival, which results in the production of more offspring than can survive.
C. Organisms that are better adapted to their environment will have a greater change of survival and reproduction.
E. There is a natural variation of traits among individuals of a species.
B. Differences in traits are determined by organism's immediate needs.
C. Organisms that are better adapted totheir environment will have a greater chance of survival and reproduction.
D. Changes within a population happen immediately when the environment changes.
The highlighted area on the map shows the location of one of Earth's biomes. Which statement best explains how the location of this biome affects climate?
It is has a hot, dry climate due to its location near the equator.
It has a hot, wet climate due to its location near the equator.
It has a cold, dry climate due to its location near the poles.
It has a cold, wet climate due to its location near the poles.
Bogs, marshes, and swamps are examples of what type of ecosystem?
desert
wetland
intertidal zones
coniferous forest
Which of the following is the largest ocean ecosystem, known for colonies of small, marine animals?
mating zones
barrier islands
coral reefs
volcanic islands
What type of aquatic ecosystem is a mixture of salt and fresh water and affected by tides?
rocky coasts
cypress swamps
oak hammocks
estuaries
Which of the following is NOT a reason why swamps have high levels of humidity?
Swamps contain many pants and animals, and the gases they produce condense in the air.
Swamps are only found in tropical regions, which contain land masses usually below sea level.
Swamps have a large tree canopy, which keeps water vapor- from evaporating into the air.
Swamps contain large amounts of silt, which allows for a high rate of consistent evaporation.
Tachinid flies are parasitic insects. They attach their eggs to hosts such as monarch butterfly caterpillars. Tachinid fly larvae later hatch and eat the hosts. Monarch butterflies are migratory insects. How will the population of tachinid flies in an area be affected if monarch butterflies do not follow their regular migration schedule?
The population of tachinid flies will decrease unless adult tachinid flies can locate other hosts.
The population of tachinid flies will increase unless adult tachinid flies can consume other hosts.
The population of tachinid flies will remain constant unless adult tachinid flies transform into other hosts.
The popuation of tachinid flies will increase, than decrease, unless adult tachinid flies transform into other hosts.
Why do more plant crops grow in grassland ecosystems than in desert ecosystems?
There is more sunlight.
There is more oxygen.
There is more rain.
There is more chlorophyll.
The picture shows a coral reef. Which of the following is correct about the interactions between living and nonliving factors in the reef?
The nonliving hard calcium carbonate of the coral provides a home for many living fish.
The living, hard shells of crabs protect the nonliving soft tissue of the crabs inside of them.
The living sunlight provides energy for the nonliving coral and algae in the reef.
The nonliving extensions of starfish allow them to grip onto the hard, living terrain in the reef.
Charles Darwin's theory that evolution was caused by natural selection explains the sequential nature of groups in the fossil record. The idea that simpler species have been replaced by later, more complex species explains the diversity of fossils. Darwin's theory of evolution.
explains how the adaptations of a species do not lead to its survival during periods of change.
explains how a new species arose separately after the previous species became extinct.
is a scientific explanation of the fossil record and modern biodiversity and has been tested by many scientists.
is a scientific explanation of the fossil record that has not been tested by many scientists.
A wildlife biologist is studying a population of penguins at the South Pole. These penguins are endangered by global warming and the destruction of their habitat. How will natural selection most likely produce change in the penguins?
Natural selection will only act upon the penguins with advantageous traits and produce increasingly disadvantageous changes within two generations.
Natural selection will only act upon the penguins with harmful traits and produce increasingly disadvantageous changes over several generations.
Natural selection will act upon the entire population of penguins to produce advantageous changes over several generations.
Natural selection will act upon each penguin individually to produce advantageous changes within one generation.

A. It has trees with fruits for food.
E. It provides many places to nest and reproduce.

A grassland environment, called a savanna would be able to support the energy needs of carnivores because:
animals that are carnivores are able to hide from predators in the high grass of the grasslands.
grasslands provide grasses and plants for carnivores to eat, which then provides food animals that are not carnivores.
grasslands have grasses and plants to eat for animals that are not carnivores, which then provides animals for the carnivores to eat.
animals that are carnivores can survive by eating leaves and plants that grasslands have.
The picture shows a tropical rain forest with a large tree canopy that lets through very little sunlight. Which of the following is a form o the life survives well in this environment?

mammals that need the ark, moist soil of forest floor in which to lay their eggs
plants that use moonlight to make food and energy for
The picture below shows a freshwater marsh environment. Which of the following is a quality of a freshwater marsh environment that allows groups of low-growing planting, such as sedges, grasses, lily pads, and reeds, to live there?

The marsh has flowing water available for the plants' roots.
The marsh has deep places that hold all of the water plants.
