How is a tendon different from a ligament? a. a tendon joins a bone to a bone; a ligament joins a muscle to a bone. b. a tendon joins a muscle to a bone; a ligament joins a bone to a bone. c. a tendon covers a bone; a ligament supplies nutrients to a bone. d. a tendon supplies nutrients to a bone; a ligament covers a bone.

B is correct. A tendon will join a muscle to a bone, and a ligament joins a bone to another bone. I think of it this way, partly influenced by my biology teacher:

- The achilles tendon, at the back of your foot, clearly joins foot to calf muscle
- The word ligament comes from 'deligare' in Latin, which roughly means to tie           together. A ligament 'ties' two bones together

I hope this helps

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
