B. they are both unicellular
There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.
Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.
Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.
chromtids are visible during interphase but for chromosomes its prophase
The glue has long flexible molecules in it called polymers. These polymer molecules slide past each other as a liquid.
Borax in water forms an ion called the borate ion. When the borax solution is added to the glue solution, the borate ions help link the long polymer molecules to each other so they cannot move and flow as easily.
When enough polymer molecules get hooked together in the right way, the glue solution changes from being very liquidy to a rubbery kind of stuff that we call slime!
