C. Fungi

The human body is made up of specialized cells that perform different functions. For example, a neuron is a specialized cell of the nervous system that receives and transmits signals throughout the body to perform these tasks, the neuron uniquely possesses branched protoplasmic protrusions, called dendrites and axons, which conduct the signals to and from its cell body. This illustrates which of the five major biological themes?

C. Interrelation of structure and function in biological systems

By definition, an organism that is eukaryotic?

On the scientific expedition into new territory, you discover a previously unknown organism living within the rainforest. This organism has a cell wall, is multicellular and heterotrophic, and has a nucleus. In what kingdom would you most likely place this organism and why?

Concept to Consider: Characteristics of this organism indicate it is a eukaryote; its structure may indicate that it belongs to the kingdom Fungi

Design a new organism that is fit for a swamp habitat. Explain how that organism would communicate with other organisms within that ecosystem and transmit information within itself and between generations.

Concepts to Consider: DNA and genes are involved in between generation communications, hormones and /or neurotransmitters within the organism, and visual or aural communication between organisms
