A few years went by with little rainfall, and the only tree species that survived had large seeds. After many generations, almost all the birds had larger beaks. How is this change best explained?
The birds with larger beaks were better at eating large seeds than those with smaller beaks, so only the birds with larger beaks got enough food to survive, reproduce, and pass the trait of large beaks to the next generation.
The birds with smaller beaks had to work harder than those with larger beaks to crack open the large seeds. The more they used their beaks, the larger their beaks became, so they were able to get enough food to survive, reproduce, and pass the traits of large beaks to the next generation.
The birds with smaller beaks grew their beaks so that they would be better able to eat the large seeds and get enough food to survive, reproduce, and pass the trait of larger beaks to the next generation.
It was a chance occurrence that all the individual birds’ beaks in the next generation were larger. They were therefore able to eat the large seeds and get enough food to survive, reproduce, and pass the trait of large beaks to the next generation.

Their new habitats have many predators that limit their population growth.
Their new habitats may not have the same predators found in their previous environment that can limit their population growth.
Capuchin monkeys live in the Amazon rainforest in the canopy of the trees, eating mostly leaves. Many acres of the Amazon forest are being destroyed for farmers to plant soybeans for crops. What will most likely happen to the capuchin monkeys?
They will become endangered.
They will start eating soybeans.
They will begin hunting humans.
They will evolve to live on the forest floor.
Which best explains how the greenhouse effect has caused a rise in global warming?
Increased production of carbon dioxide holds in heat and prevents it from escaping Earth’s atmosphere.
CFCs used in aerosol sprays have decreased the levels of radiation that enter Earth’s atmosphere.
The thickening of the ozone layer has decreased the levels of UV radiation that reach Earth’s atmosphere.
The use of heating and cooling have produced increased levels of moisture in the air, which holds in heat.
What will most likely be the result of destroying the rain forest for timber and farmland?
an increase in the populations of underpopulated areas of Earth, which should ease overcrowding in more populated areas of the planet
a permanent improvement of local economies created by the sale of the vast forest resources and the expansion of productive farmland
a marked decrease in the number of species on Earth caused by loss of habitat and increased global warming
an improvement of local water supplies as the soil is stabilized and decaying vegetation from the trees disappears
Which human activity most likely causes acid rain?
using chlorofluorocarbons (CFCs)
generating nuclear energy
burning fossil fuels
using pesticides
