Marvin predicts that if marigold flowers are planted around a group of tomato plants, then fewer insects will eat the tomatoes. Which of the following observations would BEST support Marvin's prediction?
A count of 20 insects before marigolds are planted and 20 insects after marigolds are planted.
A count of 20 insects before marigolds are planted and 12 insects after marigolds are planted.
A count of 10 tomato plants before marigolds are planted and 5 tomato plants after marigolds are planted.
A count of 10 tomato plants before marigolds are planted and 15 tomato plants after marigolds are planted.
Jorge and Nancy conducted an experiment together. They caught moths that were attracted to either white light or yellow light and recorded the data. Their results are shown on your test.
captured moths prefer yellow light
only white moths are attracted to white light
the number of moths captured per day using white light decreased each day
the number of moths captured per day using yellow light decreased after day 5
Students are investigating the effect of the number of hours per day of sunlight on plant growth. Four plants of the same species and stage of growth were used in the investigation. The plants were grown in the same amount and type of soil and watered the same amount at the same time of day. The data is shown in the next line.
plants (ABCD) hours of sunlight (1,5,3,7) growth in centimeters (0cm, 3cm,1cm,5cm)
What conclusion can be made about this investigation?
plants do not need sunlight to grow
plants grow more with fewer hours of sunlight
plants receiving more hours of sunlight grow more
plants receiving over seven hours of sunlight will not grow
Arctic foxes grow new fur with different seasons. They grow brown fur in the summer and white fur in the winter. These changes are examples of which survival characteristic?
adaptation
hibernation
metamorphosis
migration
Beetles in a certain population can either be green colored or brown colored. A change in the environment has caused the green colored beetles to become more visible and heavily preyed upon by other animals. Because of this change in the environment, what will MOST LIKELY happen to this beetle population?
the number of brown colored beetles will increase
the green colored beetles will reproduce at a faster rate
the green colored beetles will change their color to brown
the population of green colored and brown colored beetles will become extinct
The life cycle of a mosquito is based on temperature and daylight. With increased global temperatures, one species of mosquito is beginning to reproduce earlier in the year for a longer period of time. Which phrase below BEST describes this change in the life cycle of the mosquito?
a species losing habitat
a species overpopulating
a species adapting to changes in an environment
a species gaining a competitive advantage over predators
Peppered moths are found in two different color varieties a light colored variety and a dark colored variety. Two hundred years ago, light colored moths were more common than dark colored moths. The light colored moths were able to hide better from predators on the trees. As time went by the building of factories resulted in soot covering the trees making trees darker where the moths hide
more larger sized moths survived
more light colored moths survived
more dark colored moths survived
more smaller sized moths survived
Many plants that are found in a tropical rainforest have very large leaves. How would large leaves be MOST helpful for rainforest plants?
by attracting insects for pollination
by hiding the stems from predators
by collecting sunlight for making food
by shading the stems and roots from heat
Scientists studied a population of harvest mice living in a small area. Some mice have dark colored fur and some mice have light colored fur. The graph is not represented below. Which of the following would BEST explain the data in the graph?
an environmental change killed most of the plants that the mice eat
an environmental change allowed an invasive species to be introduced
an environmental change reduced the amount of water available to the mice
an environmental change caused one fur color to be more visible to predators than the other
Chameleons are reptiles that can change the color of their skin. Which of the following examples would not be a benefit of this characteristic?
to help them hunt for food
to help them attract a mate
to help them climb trees better
to help them hide from predators
The apple snail is an unusual organism because it has both gills and a lung. How might a combined respiratory system like this give apple snails an advantage over other snails without this characteristic?
the apple snail could move more rapidly
the apple snail could lay eggs with thicker shells
the apple snail could be more immune to disease
the apple snail could expand its range to find food
Which statement below describes how a specific feature of the bald eagle best helps it to survive in its environment?
its keen eyesight helps it to see prey from the sky
its white and brown feathers help it to hide from predators
its powerful toes and long talons help it to swim after prey
its sharp curved beak helps it to dig for food underground
Manatees are mammals that live in warm shallow waters. They can easily become sick and die when temperatures drop. Which behavior is most important to the survival of a manatee in changing water temperatures?
breathing at a slower rate
swimming to deeper waters
feeding more to increase body fat
migrating to natural springs of warm water
