- Q2Plants use energy from sunlight, water, and carbon dioxide to produce sugar. Which structure is found only in plant cells and helps plants capture energy from sunlight?NucleusVacuoleChloroplastCell membrane45s
- Q3Certain species of whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual reproduction for these lizards?They are smaller than lizards that reproduce sexually.A new population can be established by a single individual in a relatively short period of time.They are more likely to develop a variety of tail lengths.All the members of a population are genetically very similar and less able to survive environmental changes.45s
- Q4Which organisms in the food web shown above compete for the same food source in this environment?Grasshoppers and snakesHawks and frogsDecomposers and grassesFrogs and snakes45s
- Q5Which of these human activities is most likely to cause the excessive growth of phytoplankton in the world’s oceans?The use of chemical fertilizers that are carried by runoff into riversThe spraying of chemical herbicides that reduce carbon dioxide in the airThe mining of fossil fuels, which requires digging underground tunnelsThe logging of old-growth forests, which results in erosion45s
- Q6Many Texas caves provide a habitat for animals that live in total darkness. The caves are damp and cool, and most of the caves are rich in the mineral calcite. The diagram below shows the relationships of some organisms involved in a cave ecosystem. Based on the diagram, which of the following statements is valid?Beetles compete with bats and cave spiders.Owls are predators of bats, and bats are predators of mothsNone of the aboveSnakes prey on bats and owls.45s
- Q7A partial food web is shown. The mourning dove is a bird that is often part of this food web. Which of these describes the mourning dove when it is part of the food web shown?It has a parasite–host relationship with the robin because it uses the robin’s nest.It has a producer–consumer relationship with sugar maple trees because it gets food from the trees.It has a producer–consumer relationship with its young because it feeds its young regurgitated food.It has a predator–prey relationship with tent caterpillars because they both use the same resources from the sugar-maple tree.45s
- Q8The white-tailed ptarmigan lives at high elevations on mountains that receive a lot of snow in the winter. During the summer, the ptarmigans’ feathers are mottled brown. The birds lose the brown feathers and grow a new set of white feathers during the winter. Scientists are concerned that rising global temperatures will affect the white-tailed ptarmigan. If global climate change leads to the elimination of snow in the habitat of white-tailed ptarmigans, which adaptation is most likely to occur over many generations?Birds with white feathers will be easier to see on the ground in the summer. Over time this could lead to white-tailed ptarmigans that have white feathers throughout the year.Birds with brown feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have white feathers throughout the year.Birds with white feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year.Birds with brown feathers will be easier to see on the ground in the winter. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year.45s
- Q9The types of small organisms that live on the bottom of streams can be good indicators of water pollution. The table below groups some organisms by their tolerance of pollution. A certain stream that was historically clear and clean has become increasingly polluted with fertilizer waste over the years. Which of these describes a likely result of this pollution?Stone flies and midges thrive and compete for the same food source.Large numbers of crayfish have suddenly died.Riffle beetles have become more abundant in the stream.Mayflies that were previously abundant are no longer present in the stream.45s
