Select each statement that describes how an animal maintains homeostasis. Select three correct answers.
A.
An animal uses its sensory organs and nervous system to gather information and then responds with the animal's musculoskeletal system.
B.
An animal acquires oxygen with its respiratory system, which then interacts with the circulatory system to transport oxygen throughout the animal's body.
C.
An animal takes in food through the digestive system, and the circulatory system distributes the digested organic molecules to all the cells in the animal's body.
D.
An animal generates carbon dioxide by metabolic processes, and then concentrates this waste product in the kidneys, the primary excretory organ.

MULTIPLE CHOICE QUESTION

Under the microscope you observe the development of an unfamiliar embryo. Over several days, you observe as a cell mass (blastula) forms first, followed by the development of an embryonic stage called a gastrula. Next, the embryo continues to develop into an elongated structure with a tube that runs from one end of the embryo to the other, with only one opening to the outside.
If the mouth of the embryo develops from this opening, could the embryo develop into a starfish? (Note: A starfish is an example of an echinoderm.)
A.
Yes, because echinoderms are invertebrates that develop a mouth first, followed by the anus.
B.
No, because echinoderm embryos develop the anus first, followed by the mouth opening.
C.
No, because echinoderms are radially symmetrical and do not go through the stages of blastula and gastrula.
D.
No, because echinoderms are radially symmetrical and their mouth also serves as the anus.

bilateral symmetry
B.
spherical symmetry
C.
radial symmetry
