Co-ordination and Control
Biology · 50 practice questions
Nervous coordination (central and peripheral nervous systems, impulse transmission, reflex action); sense organs (skin, nose, tongue, eye, ear); hormonal control (animal endocrine glands and plant hormones); homeostasis (temperature, salt and water regulation).
- Apply knowledge of the central nervous system's structure and function to body coordination.
- Illustrate and differentiate reflex, voluntary and conditioned actions.
- Relate the sense organs to their functions and to detecting/correcting defects.
- State the location of endocrine glands and relate their hormones to functions.
- Examine the effects of phytohormones (auxins, gibberellin, cytokinin, ethylene) on growth, tropism, flowering, fruit ripening and leaf abscission.
- Relate hormone function to homeostasis.
Try a few questions
- Practice question 1
The eye, a mammalian sense organ, specifically is primarily responsible for the sense of
- A.sight
- B.hearing, a sense that is instead primarily associated with the ear
- C.a factor entirely unrelated to the sense of sight of any kind
- D.smell, a sense that is instead primarily associated with the nose
Show the answer
A. sight
The eye, a mammalian sense organ, specifically is primarily responsible for the sense of sight.
- Practice question 2
The iris, part of the mammalian eye, specifically functions mainly to control
- A.the conversion of light into nerve impulses, a role instead of the retina
- B.the amount of light entering the eye
- C.a factor entirely unrelated to controlling the amount of light entering the eye
- D.the focusing of light directly onto the retina, a role instead of the lens
Show the answer
B. the amount of light entering the eye
The iris, part of the mammalian eye, specifically functions mainly to control the amount of light entering the eye.
- Practice question 3
Negative feedback, a mechanism important in coordination and control, specifically functions mainly to
- A.reverse a change and help maintain a stable internal environment
- B.a factor entirely unrelated to reversing a change of any kind
- C.amplify a change continuously, with no actual mechanism to reverse it
- D.permanently alter an organism's own set internal conditions
Show the answer
A. reverse a change and help maintain a stable internal environment
Negative feedback, a mechanism important in coordination and control, specifically functions mainly to reverse a change and maintain stability.
