Question

determine if the following statements are true or false. if false rewrite the statement to make it true. 1. homeostasis refers to maintain the constancy of the external environment around the body. 2. through negative feedback, constancy of a characteristic is maintained without slight fluctuations of its value. 3. few body systems contribute to homeostasis. make a flow map of the levels of organization of the body. atoms → molecules → macro molecules → organells → cell → tissue → organ → organ system → organism

Explanation:

1. The statement is false. Homeostasis refers to maintaining the constancy of the internal environment around the body, not the external one.
2. The statement is false. Through negative - feedback, constancy of a characteristic is maintained with slight fluctuations around a set - point.
3. The statement is false. Many body systems contribute to homeostasis, not few. The flow - map of the levels of organization of the body is correct. It goes from atoms to molecules, macromolecules, organelles, cells, tissues, organs, organ systems, and organisms.

Answer:

1. False. Homeostasis refers to maintaining the constancy of the internal environment around the body.
2. False. Through negative feedback, constancy of a characteristic is maintained with slight fluctuations of its value around a set - point.
3. False. Many body systems contribute to homeostasis.

Flow - map of body organization: Atoms → Molecules → Macromolecules → Organelles → Cells → Tissues → Organs → Organ Systems → Organism
