Examine the physical characteristics of the frog and determine if it is a vertebrate or an invertebrate. be sure to justify your answer.

A vertebrate is an animal which has a series of nerves running down from its brain to its back and are covered by special bones. These bones are called as vertebrae make up the spine which protects the nerves and provides the animals a wide range of motion.

Frogs are classified as amphibians and live in forest areas near water bodies and are different from reptiles as they lay eggs in water and not on land.

The physical characteristics of frogs classify them as vertebrates as they possess a full skeletal structure including the spinal cord.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
