1 answer:

5 0

During contraction, the filaments slide past he thick filaments, shortening the sarcomere. The thick and thin filaments do the actual work of a muscle, and the way they do this is pretty cool. Thick filaments are made of a protein called myosin. At the molecular level, a thick filament is a shaft of myosin molecules arranged in a cylinder. Thin filaments are made of another protein called actin. The thin filaments look like two strands of pearls twisted around each other.

i have a freind thats a girl and she has been being mean i need to move on but i dont know how or who to move o to what do i do

IceJOKER [234]

I would say that if she is being mean you can first try to talk it out with her (because relationships may take work sometimes and if she is really important both of you will be willing to put in the work), but if that doesn't go well and you really don't think it is going to work you should go to your other friends or family for support especially if she was a very important part of your life.
