Answer:
An isometric training is a static contraction of a muscle.
Explanation:
An isometric training is a type of exercise which involves the static contraction of a muscle where no visible movement in the angle of the joint occur. Isometric exercises helps in maintaining and recovery of strength of our body. They can also build strength, but not very effectively like other exercises. During isometric training, the muscles doesn't change its length and the affected joint doesn't move from its place.
Blood vessels keeps clots from sticking as long as their endothelium is intact and healthy.
Answer:
A. play a role establishing and maintaining membrane lipid asymmetry
Explanation:
Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:
- flipases-move lipids from the exterior to the interior side of the membrane, energy required
- flopases-move lipids in reverse comparing to flipases, energy required
- scramblases-no energy required, bidirectional
Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).
