Most animals in Animalia have backbones, but not all.
The correct answer would be C, because all organisms in Animalia are heterotrophs which means that they depend on other organisms (like animals and plants) for food.
This is called 'controlled' or 'prescribed' burning. Usually fires in the environment are regarded as undesirable and dangerous, but fires actually fulfil an important ecological role, and animals and plants had adapted to a certain frequency and intensity of fires. The seeds of some trees or grasses germinate after forest or grass fires, as the more open conditions after a fire allows the seedlings to compete and avoid being shaded and smothered by more established trees. Unfortunately, farming and forestry practices have in many cases resulted in a reduction of fires. A reduction in the frequency of fires also allows the build up of dead wood, and when a wild fire does occur, the amount of available fuel results in very hot, large and damaging fires. Therefore, management of forests and other environments such as prairies often use controlled burns to avoid the buildup of dead organic mass and to replicate the natural fire cycle.

Answer:
The correct option is a. "increased cortical mass, increased numbers of neurons, increased synaptic connections, increased neurotransmitter amounts, and increased myelination.
"
Explanation:
Rodents that have been raised in enriched environments were found to have thicker cerebral cortex containing approximately 25% more synapses in a study conducted by Mark Richard Rosenzweig. This increase in <em>synapses</em> implies in an increase in <em>neurons</em> and <em>neurotransmitters</em>, which also indicates an increase in <em>myelination</em>.
