Asmall amount of muscle tension and muscle definition (the appearance of muscle beneath the skin) is present even in a relaxed muscle. a person who is physically fit due to regular exercise, will have more of this characteristic of muscle tissue than someone who is not fit. what is this characteristic?

   Muscle tone

Explanation:  Muscle tone is actually a muscle tension. This tension (muscle tone) maintains the body in its position as it is, or in a particular desired position. Or, for example, during movement, when the body changes its position, these changes of position are regulated by muscle tone. When the body is at rest, some muscle tension exists, and depending on the general fitness of the body, that tension under the skin is more visible or less visible, that is, my muscles will be tighter or floppy.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
