- Q1The diagram shows a food web in an ocean ecosystem. The food web contains seven species of diatoms, the producers in this ecosystem. Predict how the sustainability of the ecosystem would change if the number of species of producers increased from seven to fourteen.The sustainability would increase because the lower the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.The sustainability would increase because the greater the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.The sustainability would decrease because the lower the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.The sustainability would decrease because the greater the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.120s
- Q2Different ecosystems support different levels of biodiversity. Which ecosystem would you expect to be the most sustainable after a major environmental disturbance, such as a flood?tundratropical rain forestdesertgrassland120s
- Q3The food web below represents a desert ecosystem with a high amount of biodiversity. If the population of sagebrush lizards in this ecosystem is decreased due to a disease, which best describes how the ecosystem will remain sustainable?The coyotes will consume more golden-mantled squirrels and pronghorns.The population of ants will decrease due to the decrease in the sagebrush lizard population.The golden-mantled squirrels will eat more prickly pear cactus.The badgers will no longer have any food sources and their population will decrease.120s
- Q4Pet breeders carefully choose mates for their animals to increase the chance of obtaining offspring with the desired traits. Which is not an example of a trait a pet breeder is likely to want?Snakes that are more likely to get diseases.Birds with brighter and more beautifully colored feathers.Dogs that have stronger backs so they can avoid injury.Cats with better personalities that get along well with children.120s
- Q5In most bird species, the colors on the feathers of males are bright and the colors on the feathers of the females are duller in comparison. Bright colors on males help them to attract female birds for mating. Dull colors on females help to hide them from predators as they sit on their nests to hatch eggs. Which statement does not correctly explain the variation in color between male and female birds?Bright colors help most female birds attract male birds for mating.Bright colors help most male birds attract female birds for mating.Male and female birds of the same species have different roles, so their coloration is different to help them survive.Dull colors help camouflage female birds and hide them from predators.120s
- Q6Maria’s teacher showed the class these two drawings of birds. These birds are the same species, but they have slightly different features. The teacher asked the students to compare the two birds. Each student hypothesized how a variation might help one bird survive better than the other. Which is not a reasonable explanation of how a feature might help one bird survive longer than the other?Bird A is a darker color. This might help camouflage it.Bird B has a larger beak. This might help it eat seeds or insects with hard shells.Bird A is smaller. This might make it look more beautifulBird B has larger feet. These might help it hold onto tree branches more firmly.120s
- Q7Jordan researched the five species of wild finches shown below for a science project. He hypothesized that the five species all came from the same ancestor. Through natural selection, different finch populations developed different traits. Which statement identifies a trait that differs for these finch species and explains how the change was caused by natural selection?The trait is that they have feathers. Feathers keep birds warm and lightweight and enable most to fly.The trait is that they are birds. These finches started out with just one mated pair. As the pair had offspring, more and more birds were hatched.The trait is beak shape. Bird breeders bred these different shapes of beak as experiments to see if they could make finches eat different foods.The trait is beak shape. Over time, some finches survived better than others depending on how well their beaks worked to eat available food or use tools. They passed on their beak shapes to their offspring.120s
- Q8Thousands of vegetable plants are bred by gardeners, including carrots, lettuce, and green beans. Which is the most unlikely trait to be chosen by a gardener during selective breeding of a carrot plant?resists insects and plant diseasesproduces carrots with a sweet tasteproduces carrots that do not stay fresh for very longproduces large carrots120s
- Q9The diagram shows living things in their natural habitat. Which is not an example of an external physical adaptation that enables an organism to live in this environment?spines of cactus that discourage animals from eating the plantmuscles of snake that enable it to movelarge ears of hare that help keep it coolcolor of lizard that allows it to blend in with rocks120s
- Q10Pedro made this drawing of an insect on a field trip. He compared it with the dichotomous key his class made of the different insects they saw that day. Examine the drawing. Fill in the blanks in the labels and use the dichotomous key to identify the insect.four wings, wings shaped like fingers, it is a dragonflytwo wings, wings shaped like fingers, it is a mosquitotwo wings, wings shaped like fingers, it is a dragonflyfour wings, wings shaped like triangles, it is a butterfly120s
