Homework Answers
Answer 280: B) Force.
Force generation by the muscles is affected by the speed of contration because force is directly proportional to speed.
Answer 290: B) Tonicity.
Tonicity is the elastic tension of the muscles that depend on the length of the muscle fibre.
Answer 300: B) Central.
Central nervous system include both brain and spinal cord.

Questions 1 pts Humans and many other diurnal animals have three types of cones - one stimulated maximally by blue light, a second maximally stimulated by green light, and a third stimulated maximally by red light. How can human beings see colors such as orange, yellow and purple? When red cones are stimulated, they inhibit blue and green cones. When blue cones are stimulated, they inhibit only green cones. Green cones when stimulated, do not inhibit other cones, but do...
