Frogs are amphibians. Like all amphibians, frogs are cold-blooded, meaning that their body temperatures change with the temperature of their surroundings. When temperatures drop, some frogs dig burrows in the mud at the bottom of ponds. They hibernate in these burrows until spring, perfectly still and barely breathing. Frogs can be found just about anywhere there's fresh water, on all continents except Antarctica. Though they thrive in warm, moist tropical climates, frogs also live in deserts and high on 15,000 foot mountain slopes. The Australian water-holding frog is a desert dweller that can wait for seven years for rain. It burrows underground and surrounds itself in a transparent cocoon made of its own skin. Frogs' skin is critical to their survival. Through it, they drink and breathe. Frogs don't swallow water; they get the moisture they need through their skin. And although frogs have lungs, they rely on the oxygen they absorb through their skin, especially when they're underwater. Frogs must keep their skin moist. Otherwise, oxygen does not easily pass through it and the frog suffocates. Even though frog skin secretes a mucus that helps keep it moist, their skin tends to dry out easily, which is why they usually stay near bodies of water.
Consider the bar graph comparing the number of frogs in four different habitats. Based on the information above about frogs, what is the MOST LIKELY factor limiting the frog population?
A) competition
B) food
C) space
D) water

Extinction is a natural part of life on Earth. During the history of life on Earth most of the species that ever existed have evolved and then gradually went extinct. Species go extinct because of natural shifts in the environment that take place over long periods of time, such as climate change due to an ice age. Today, species are going extinct at an accelerated and dangerous rate, because of non-natural environmental changes caused by human activities.
Which would not be considered a human activity contributing to the loss of biodiversity on Earth?
A) habitat loss
B) asteroid impact
C) over exploitation
D) impact of non-native species

Lichens are among the slowest-growing organisms, but their tolerance of environmental extremes enables them to colonize habitats where few other macroscopic organisms can grow. They grow where neither the fungal partner (mycobiont) or the photosynthetic partner (photobiont) could survive alone, because they benefit from their unique symbiotic association.
What mutualistic behaviors aid in the survival of both organisms?
A) The photobiont processes and provides nitrogen and carbon products to the mycobiont.
B) The photobionts are protected and able to grow in conditions in which they could not grow alone and in return release glucose in some form to the mycobiont.
C) The photobionts absorb mineral nutrients from the underlying surface or from minute traces of atmospheric contaminants while the mycobionts synthesize organic nutrients from carbon dioxide.
D) The photobionts produce ammonium and organic sodium compounds from N2 gas by sodium fixation; that in turn, aids the mycobionts in producing enzymes to decompose the substrate on which they live.
