5 dot points across 5 inquiry questions. Click any dot point for a focused answer with worked past exam questions where available.

How does the body keep its internal conditions steady, and how does feedback make that work?

Explain how organisms maintain homeostasis through feedback mechanisms, and how body systems work together to keep internal conditions stable (NGSSS Reporting Category 3, Organisms, Populations, and Ecosystems).
A benchmark-level answer on homeostasis for the Florida Biology 1 EOC: the meaning of homeostasis, negative feedback (with body-temperature and blood-sugar examples), positive feedback, and how body systems cooperate.

How do the organs and tissues of a plant carry out transport, support, reproduction, and photosynthesis?

Relate the structure of plant organs and tissues to their function, including transport, support, reproduction, and photosynthesis (NGSSS SC.912.L.14.7; Reporting Category 3, Organisms, Populations, and Ecosystems).
A benchmark-level answer on plant structure for the Florida Biology 1 EOC: roots, stems, leaves, and flowers, the transport tissues xylem and phloem, support, reproduction, and the leaf as the site of photosynthesis.

How does the cardiovascular system move blood around the body, and what affects how it flows?

Describe the structure and function of the cardiovascular system and the factors affecting blood flow through it (NGSSS SC.912.L.14.36; Reporting Category 3, Organisms, Populations, and Ecosystems).
A benchmark-level answer on the cardiovascular system for the Florida Biology 1 EOC: the heart, blood vessels, the path of blood, the function of blood, and the factors that affect blood flow.

How does the immune system defend the body, and how do vaccines and antibiotics help?

Explain the basic functions of the human immune system, including specific and nonspecific immune responses, vaccines, and antibiotics (NGSSS SC.912.L.14.52; Reporting Category 3, Organisms, Populations, and Ecosystems).
A benchmark-level answer on the immune system for the Florida Biology 1 EOC: nonspecific and specific defenses, antibodies and white blood cells, immunological memory, how vaccines work, and why antibiotics treat bacteria but not viruses.

How does the nervous system detect and respond to changes, and what do the main parts of the brain do?

Describe the structure and function of the nervous system, including the major parts of the brain, and its role in responding to stimuli and maintaining homeostasis (NGSSS SC.912.L.14.26; Reporting Category 3, Organisms, Populations, and Ecosystems).
A benchmark-level answer on the nervous system for the Florida Biology 1 EOC: neurons and the stimulus-response pathway, the central and peripheral nervous systems, the major parts of the brain (cerebrum, cerebellum, brain stem), and the role in homeostasis.
