Nervous system involves transmission of impulses from the receptors to the effector cells. it involves the detection of the stimuli by the receptor cells (includes the skin,eyes,mouth), then the stimuli is carried by the sensory neurone (joins the receptor cells and the spinal cord) to the central nervous system (the spinal cord), then the impulse is picked by the relay neurone and taken to the brain for processing, where the brain interprates the stimuli and sends a response. then the relay neurone from the brain joins to the motor neurone which connects the brain and the effector cells. The motor neurone carries the message to the effector cells (muscles and the glands), and finally a response is experienced in the specific place of the body by either movement of body muscles or secretions by the glands.
Oxygen and nutrients are transported around an animal's body by the circulatory system.
<span>Circulatory system or cardiovascular system includes the circulating blood with the role in the transport of nutrients oxygen, carbon dioxide, hormones, and blood cells. Besides the transport function, it also stabilizes temperature and pH, and maintain homeostasis. The circulatory system is divided into <span>a systemic circulation and a pulmonary circulation.</span></span>

Answer:
PROTIST, FUNGI, PLANTS
Explanation:
The Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi. Characteristics of Protists: mostly unicellular, few multicellular, eukaryotic, can be heterotrophic or autotrophic. Ex: algae, Paramecium, kelp (multicellular).
