Geographic isolation caused the separation of rainforest frog populations into a population in the north and a population in the south. The separated populations later reconnected because the climate got wetter and warmer, causing the rainforest to expand. When males from the north mated with females from the south, the offspring failed to develop past the tadpole stage. When males from the south mated with females from the north the offspring developed more slowly than the offspring of pairs of northern frogs. These data support that which event occurred while the two populations of frogs were separated?
A)The two populations mated with other species of frogs.
B)The two populations developed into new species.
C)The two populations began a new method of reproduction.
D)The two populations had fewer offspring than before the separation.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
